The National Snow and Ice Data Center (NSIDC) in Boulder, Colorado houses thousands of photographic prints of glaciers taken from the ground, the air, and from space. These photographs constitute an important historical record, as well as a data collection of interest to those studying the response of glaciers to climate change. A portion of the analog photographs have been scanned and made available in digital form, along with a large number of additional photographs that came to NSIDC in digital form. Most of the photographs are of glaciers in the Rocky Mountains, the Pacific Northwest, Alaska, and Greenland. However, the collection does include a smaller number of photos of glaciers in Europe, South America, the Himalayas, and Antarctica. Updates to the Glacier Photograph Collection are ongoing but occur at irregular intervals. The collection includes a number of sub-collections or Special Collections that are distinguished in some way, as described in the documentation. For example, there is special collection of Repeat Photography of Glaciers that provides a unique look at changes in glaciers over time. The photos are available online via a searchable interface and are retrievable by glacier name, photographer name, date, country, state, and geographic coordinates.
Glaciers are sensitive to the temperature and precipitation fluctuations accompanying climate change. Many of the world's glaciers are retreating in response to warmer temperatures. This retreat is often marked by an obvious change in glacier terminus location. For an example, see Mountain Glaciers on the NSIDC State of the Cryosphere Web page. Because of this sensitivity to climate change, historical photographic collections of glaciers are important to the study of the climate record.
NSIDC's Analog Archives Collection houses more than 20,000 glacier photograph prints as well as approximately 100,000 imaged on microfilm. This collection of prints is fragile; and to view the collection, users must travel to NSIDC; or NSIDC staff may search the print collection for users. Because of this, the climatologically and historically significant analog collection has relatively few users. To help rectify this situation, NSIDC partnered with the NOAA Climate Database Modernization Program (CDMP) to digitize a large portion of the photographic prints and make them available through a searchable interface. NSIDC released the first iteration of the digital Glacier Photograph Collection in December 2002.
CDMP was a partnership between NOAA and private industry to image and key paper and microfilm records and then make them available online to members of the climate and environmental research community, as well as the public at large. In partnership with NOAA and the CDMP program, additional glacier photographs, numbering in the thousands, were scanned and added to the online collection at NSIDC. The CDMP program ended in 2011. As of 2016, we are planning to digitize the remaining photographic prints in the analog collection in partnership with the Digital Library at the University of Colorado at Boulder (CU). This partnership is made possible by a grant from the Council on Library and Information Resources (CLIR).
The digital Glacier Photograph Collection began with a little over 1,000 photographs in 2002 but has grown to over 16,600 as of August 2016. Through the years, it has also grown to encompass special collections of glacier photographs that include Repeat Photography of Glaciers, the Antarctica Dry Valleys Glacier Photographs, NASA Astronaut Glacier Photographs, DAHLI IGY Glacier Photographs, National Park Service Glacier Surveys Report, and photographs from the World Glacier Monitoring Service. For more information on these, see the Special Collections section of this document.
The Glacier Photograph Collection is one component of the Global Terrestrial Network for Glaciers (GTN-G). GTN-G is the framework for the internationally coordinated monitoring of glaciers and ice caps in support of the United Nations Framework Convention on Climate Change.

This section explains the file naming convention used for this product with examples. The filenames of all of the photographs were created with the Photo ID followed by the image format extension. Most Glacier Photograph Collection Photo IDs are assigned at NSIDC based on the name of the glacier, the year/month/day of the photograph, and an index number; however, there are exceptions to this rule that are noted below. Note that all three sizes of the image of a particular glacier photo (thumbnail, reference, and archive) have the same base file name but may have a different extension (.jpg or .tif) depending on the format. The associated ASCII text metadata file also has the same filename as the photograph but with a .txt file extension.
Example File Name: agassiz1913081501.tif
Generic File Name: glacier_nameYYYYMMDDXX.ext
|glacier_name||The name of the glacier|
|YYYY||4-digit year that the photo was taken. If the year is not known 9999 is the fill value.|
|MM||2-digit month of the year the photo was taken. If the month is not known 99 is the fill value.|
|DD||2-digit day of month that the photo was taken. If the day is not known 99 is the fill value.|
|XX||2-digit photo index number|
|.ext||File extension: .jpg, .tif or .txt|
Users should note that photographs without glaciers have a Photo ID starting with noglacier and a glacier name of NoGlacier. Images without glaciers are provided as a reference for historical context. For example, some of the NoGlacier images are photographs of the surrounding area of the glacier. Unidentified images where the name of the glacier is not known are given a Photo ID starting with unknown and given a glacier name of Unknown in the database.
For the Reid collection, the Photo IDs are similar to charpentier1892_353, which refers to the glacier name, the 4-digit year the photograph was taken, and the 3-digit number assigned to the photograph by Reid. See the Analog Collection for more information about these photographs.
For the Greenland collection, the Photo IDs are based on the glacier name, followed by the characters GI, then a 2-digit box number, and finally a 2-digit slide number within each box. For example, the glacier identifier of hayesGI01_02 refers to Hayes Glacier in Box 1 and it is the second slide from that box. See the Analog Collection for more information about these photographs.
The Photo IDs for the National Park Service (NPS) Rocky Mountain National Park (RMNP) Glacier Survey Reports are assigned based on the 4-character park code, the 4-digit year of the RMNP report, the name of the glacier, the 4-digit year of the glacier photograph, and a 2-digit unique identifier used with every photograph. The first eight characters of the Photo ID are coded to match the photographs in the original report. For example, the Photo ID of rmnp1939_andrews190901 refers to the RMNP report from 1939 of Andrews Glacier which was taken in 1909 and it was the first in the series. See the Special Collections section for more information on these photographs.
The Photo IDs for the Austin Post and USGS ICP aerial photographs are assigned based on the original photograph print number beginning with USGS, the 2-digit year the photograph was taken, camera angle (V: vertical, H: horizontal), 1-digit roll number, and 3-digit image number. For example, the Photo ID of USGS92V1_053 references that USGS was the supporting project, that the photograph was taken in 1992, that the image was a vertical camera angle, and that it was Image 53 on Roll 1. See the Analog Collection for more information about these photographs.
The Photo IDs for the Dry Valleys photographs were created by the Data Conservancy group at Johns Hopkins University. They begin with McDV_FieldPhoto referencing the McMurdo Dry Valleys, followed by the 4-digit year the photo was taken, and then a 5-digit photo counter number. For example, McDV_FieldPhoto_1993_00311 is photo 311 of the 1993 season. See the Special Collections section for more information on these photographs.
The Photo IDs for the Lake Clark National Park photographs all begin with lacl_. The rest of the ID is a differing combination of the image number, with or without the glacier name and the photograph date. For example, lacl_1987_ahoglacier_870817_diff8, lacl_dsc00195, and lacl_img_0034. See the Special Collections section for more information on these photographs.

The photographs are primarily of glaciers in Alaska, Greenland, the Pacific Northwest (U.S. and Canada), and the Rocky Mountains, along with some from Europe and South America. The latitude and longitude reported for each photograph is the location of the glacier, not the point from which the photograph was taken. The Glacier Photograph Collection refers to glaciers in the mountain ranges along the Alaskan/Canadian border as occurring in both Alaska and Canada. Figure 1 shows a map with the location of glaciers in this data set.
The earliest glacier photograph in the Glacier Photograph Collection is from 1857, and the most recent is from 2015. Some photographs are of the same glacier and comprise a special Repeat Photograph Collection that provides a unique look at changes in glaciers over time.

NSIDC worked with the CDMP contractor to check the quality of image files during the initial digitization project in 2002. Most image files of digitized photographs were checked for correct file name, proper digitization, and proper image size at NSIDC and were digitized again by the contractor if deemed necessary.
A variable degree of uncertainty surrounds the metadata for each image. See The Digital Collection section of this document for more information.
Most latitudes and longitudes were determined in 1981 when NSIDC staff created an Index of Metadata for some of the NSIDC analog glacier photograph collection. When creating the online database, if no location information existed for the individual photos, NSIDC staff researched published literature or referred to the Geographic Names Information System (GNIS) for latitudes and longitudes.
Some photographs have more than one glacier and some degree of subjective judgment was necessary to document metadata for these photographs. In these cases, NSIDC staff referred to the original labels associated with the photographs.
In 2015, in order to facilitate the addition of more photos from crowd sourced photographic web sites like Flickr Creative Commons and Wikimedia Commons, the requirements for digital photos have been loosened, thus some high-resolution photos are suitable for digital applications but are not suitable for print.
NSIDC houses thousands of glacier photographs as prints and on microfiche. The largest single collection of print images at NSIDC, comprised of roughly 5000, is the American Geophysical Union/American Geographical Society (AGU/AGS) Collection, donated to NSIDC/World Data Center (WDC) for Glaciology by William O. Field in the late 1950's. Field was the head of the Department of Exploration and Field Research at the AGS from 1947 until he retired in 1969. Field took many of the photographs and assembled them for the AGU research committee. It was because of this collection, that in 1957, the International Geophysical Year (IGY) committee awarded the WDC for Glaciology to Field and named him as the first director. He maintained the collection until the WDC was moved to the United States Geological Survey (USGS) in Tacoma, WA in 1970 and ultimately to Boulder, CO in 1976.
The photographs in the AGU/AGS Collection are primarily of Alaskan glaciers but also include the Pacific Northwest (U.S. and Canada), the Rocky Mountains, and Europe. Field indexed the photos by region and drainage system. For example, he indexed Alaskan glacier photos starting in the southeast corner of the state, continuing north and west, following each drainage basin in a counterclockwise direction. This method enables photos of neighboring glaciers to be filed next to each other. This filing system is used for the entire collection and subsequent donations are filed into this system as well. It is from this collection that the first photographs were selected for the CDMP digitization project.
The AGU/AGS Collection that Field donated to NSIDC/WDC for Glaciology also included the Harry F. Reid collection. Reid, America’s first geophysicist (Gillispie 1975), traveled to Glacier Bay, Alaska, in 1890 and 1892 in order to photograph and map the area. Collected by Field after Reid’s death in 1945, the materials include approximately 600 glass plate negatives and prints, 22 expedition notebooks, and approximately one cubic foot of manuscript materials that include drafts of Reid’s map of Glacier Bay. Also included are photographs taken during Reid’s trips to the Alps from 1894 through 1901. Users should note that some of the photographs taken by Reid were of the local area and not of an actual glacier. The Reid photographs without glaciers were given a glacier name of NoGlacier in the database.
Copies of the Austin Post aerial photograph collection became a part of the WDC for Glaciology collection when the WDC was transferred to the USGS in Tacoma in 1970. This collection of photographs, the Post-Mayo-Krimmel (PMK) Collection, comprises approximately 100,000 photographs, almost all of which are only available on microfilm at NSIDC.
The Greenland photograph collection was donated to the WDC for Glaciology in the mid 1980s by Captain Ron Kollmeyer of the U.S. Coast Guard (USCG). Captain Kollmeyer was the lead for the Greenland Glacier Survey. More than 1,200 color slides have been digitized and are available via the online Search & Order interface. The photographs of western Greenland glaciers were taken between 1969 and 1980 from ground observation stations and from USCG helicopters at an altitude of between 100 and 1,000 feet.
The WDC for Glaciology program was retired in the mid 2000's; the analog collection is now supported solely by the NOAA@NSIDC program. Unfortunately, NOAA@NSIDC does not have resources for storing all analog glacier photographs under archival quality conditions. As a consequence, some are in danger of deterioration. This gives urgency to our digitization work. Allowing researchers to access high-quality digital reproductions of these fragile and rare photographs limits the need to use the original archival image and aids in the preservation of the originals.
Figure 4. A Selection of Glacier Photograph Prints Prepared for Shipment to the CDMP Contractor for Digitizing. Click image for larger version.
The NOAA Climate Database Modernization Program (CDMP) ran for 12 years from 2000 to 2011. In partnership with NOAA NGDC and SourceHOV, a CDMP corporate partner, NSIDC digitized selected analog photographs for online distribution. The goals of the CDMP Glacier Photograph Digitization Project were the following:
NSIDC selected images for digitizing that were held by NSIDC with no copyright restrictions that were of good quality and that show substantial portions of glaciers. The original black-and-white photographic prints range in size from 2 x 3 inches to 8.5 x 11 inches. Figure 4 shows a picture of some of our analog archive holdings.
The following requirements were provided to the CDMP contractor for digitizing the photographs:
Metadata for the digitized images are compiled at NSIDC in an Excel spreadsheet that is uploaded to a Postgres database. Metadata for the initial release of about 1,000 glaciers in 2002 was derived primarily from the Glacier Photograph Collection Index, a project started in the late 1970s by NSIDC staff. This index, or inventory of glacier names with metadata for some of NSIDC's analog glacier photograph collection, is housed at NSIDC on paper and on microfiche. The metadata covers many aspects of the individual photos, including the altitude at which a photograph was taken, date, photograph number, latitude/longitude, mountain range, and drainage system. Not all of the aspects were included in the metadata for the digitized images.
The keyword headings used for the Index project were Terminus, Medial moraine, Terminal moraine, Lateral moraine, Firn line, All of glacier, Rock glacier, and Other. Transcribing the Index information was too labor intensive to be sustained, so NSIDC assigned keyword terms by looking at the photographs. Only glaciers in the first release of about 1,000 photographs have keywords assigned. The keyword heading for glaciers in all subsequent releases are blank.
NSIDC used the USGS GNIS to look up geographic coordinates of most glaciers. For those glaciers that did not appear in the GNIS or when more than one entry for the same title appeared, NSIDC determined approximate coordinates by either referring to the original photos (for hand-written information from the photographer), or by doing Web-based research, including Topozone or Terraserver, to estimate coordinates near the middle of the glacier.
In 2015, in order to facilitate the addition of more photos from crowd sourced photographic web sites like Flickr Creative Commons and Wikimedia Commons, the requirements for digital photos have been loosened, thus some high-resolution photos are suitable for digital applications but are not suitable for print.
As the Glacier Photograph Collection has progressed over the years, a need to identify special collections within the main collection arose based on type of images, the region, or the entity that compiled them. It began with the Repeat Photography of Glaciers collection in 2006 with five other special collections added as of 2015.
Figure 5. Muir Glacier Pair
On the left is a photograph of Muir Glacier taken on August 13, 1941, by glaciologist William O. Field; on the right, a photograph taken from the same vantage on August 31, 2004, by USGS geologist Bruce F. Molnia. According to Molnia, between 1941 and 2004 the glacier retreated more than twelve kilometers (seven miles) and thinned by more than 800 meters (875 yards). Ocean water has filled the valley, replacing the ice of Muir Glacier; the end of the glacier has retreated out of the field of view. The glacier's absence reveals scars where glacier ice once scraped high up against the hillside. In 2004, trees and shrubs grow thickly in the foreground, where in 1941 there was only bare rock.

As Harrison wrote in 1960, "The glacier story is always changing, but it can be caught and preserved with the proper use of a camera" (pp 1). Glacier photographs taken from the same vantage point but years apart in time often show changes in the glacier terminus position that may be indicative of climate forcing. Tidewater glaciers may exhibit shorter term cycles of terminus advance and retreat as well. These repeat photographs are of special interest to glaciologists. The Glacier Photograph Collection contains many photographs of the same glaciers, but relatively few repeat photographs.
This special collection displays photographs of the same glacier, taken from the same vantage point, at the same time of year, but taken many years apart. These photographs can show evidence of glacier and climate changes over time. Repeat photography can reveal dramatic changes in the glacier terminus position, as a glacier either advances or retreats. Most glaciers around the world have retreated at unprecedented rates over the last century. These pairs of photographs can provide striking visual evidence of climate change.
In March 2006, Dr. Bruce F. Molnia, a glaciologist with USGS, collected and contributed repeat glacier photographs. He had taken many of the later ones himself and had digitized the earlier ones from data collections. These are identified in the Source metadata field as U.S. Geological Survey (distinguished from USGS Photo Library, which refers to USGS historic collections). Notes and Keyword metadata fields are based on information from Dr. Molnia. In June of 2006, Matt Nolan donated repeat photographs to this collection; and Lonnie G. Thompson contributed repeat photographs in July of 2007. Figure 5 shows an example of the glacier pairs found in this special collection of 110 photographs. To access this subset, see the Search & Order interface; the Choose a Collection drop-down list will already have Repeat Glacier Photographs selected.
RMNP began conducting glacier surveys at the request of Francois E. Matthes in 1932. The National Park Service donated copies of the glacier survey reports to Matthes for the International Committee on Glaciers (now called the International Association of Cryospheric Sciences). For a history of the committee from 1894 to 1994 and its subsequent transformations, see the The International Commission on Snow and Ice (ICSI) and its Precursors, 1894-1994 PDF document (Radok 1997). Matthes later donated his collection to NSIDC/WDC for Glaciology. NSIDC holds reports from the years 1932-1952; these reports include 265 glacier photographs. Several of the reports combine more than one year into one report, and not all of the reports contain photographs. The 265 images in the reports were digitized and added as the National Park Service Glacier Photographs special collection in January 2008.
Note: Metadata in the Notes field were taken from the captions associated with the photographs in the reports. To view the photographs in context, see the associated PDF file on the Rocky Mountain National Park Glacier Survey Reports Web page. To obtain high-resolution versions of the photographs from the park reports, see the Search & Order interface; the Choose a Collection drop-down list will already have National Park Service Glacier Photographs selected.

This special collection is from Alaskan glacier surveys led by William O. Field during IGY, 1957-1958 that was a follow on to the first two International Polar Years (IPY) 1882-83 and 1932-33. Glaciology was one of the primary research areas studied during IGY. Discovery and Access of Historic Literature from the IPYs (DAHLI) program (now called the International Polar Year Historical Data and Literature collection) sought to locate, identify, preserve, catalog, and digitize data, literature, photographs and other materials from the first three IPY events: 1882-1883, 1932-1933, and 1957-1958 (IGY).
These photos, taken between 1957 and 1959, represent an attempt to systematically study glacier change in Alaska. These 2154 images comprise the DAHLI IGY Glacier Photograph collection and were added to the broader Glacier Photograph Collection in March 2008. To access this collection, see the Search & Order interface; the Choose a Collection drop-down list will already have DAHLI IGY Glacier Photographs selected.
Added in June 2010, this special collection of 500 photographs was taken by NASA astronauts on the International Space Station and the Space Shuttle Endeavor. These photos were taken between 1994 and early 2010. The photos were collected in collaboration with the NASA Gateway to Astronaut Photography of Earth project. The goal is to make these photos more widely available and discoverable. To see the photos, go to the Search & Order Interface; the Choose a Collection drop-down list will already have NASA Astronaut Glacier Photographs selected.
This special collection of 24 photos, added in March 2011, consists of field photographs from the McMurdo Dry Valleys region of Antarctica. While the valleys themselves are notably ice-free, a number of glaciers terminate in the valleys, some acting as outlets to the East Antarctic Ice Sheet. Studies show that the majority of the glaciers in this area are receding. Glaciers were photographed in the course of geologic studies and help document the conditions of the glaciers and how they may have changed. These photos were originally made available through a pilot project of the Data Conservancy at Johns Hopkins University (JHU). Prior to December 2014, the high-resolution digital images were archived at JHU. After that, the collection of 24 images was moved to the archive at NSIDC when the pilot instance of the Data Conservancy was decommissioned. To see the photos, go to the Search & Order Interface; the Choose a Collection drop-down list will already have Antarctica Dry Valleys Glacier Photographs selected.
The World Glacier Monitoring Service (WGMS) compiles and disseminates standardized observations on glacier fluctuations such as length, area, volume, and mass. This special collection of 1192 photos, added in May 2015, focuses on photographs of glaciers for which long fluctuation series are available, some of them dating back to the 19th century. The photos were assembled from the WGMS archive, from contributions from WGMS principal investigators, and from various other sources that provide freely available data. The main sources include the WGMS Fluctuations of Glaciers (FoG) database, the archive of Bavarian Glaciers, the Glaciers Online collection prepared by Jürg Alean and Michael Hambrey, photos from the Interactive Repeat Photo Comparisons of Various Swiss Glaciers project conducted by Simon Oberli, the Swiss Glacier Monitoring Network, and work shared by researchers and students associated with the WGMS. Additionally, photographers who freely share their work on platforms such as Flickr Creative Commons and Wikimedia Commons contributed significantly to this collection.
Most photographs in this collection were born digital. In some instances, photographer names are Wikimedia or Flickr usernames under which the photographers published their work. Image size and resolution vary widely; while some images may be of print quality, others offer resolutions limited to digital applications. The collection was assembled by WGMS/NSIDC graduate interns Rebecca Navarro, Julien Bodart, and Mylène Jacquemart in late 2014 and early 2015. For more details on the development of this special collection, see the WGMS Internship Report: Growing the Glacier Photograph Collection (Jacquemart 2015). To see the photos, go to the Search & Order Interface; the Choose a Collection drop-down list will already have WGMS Glacier Photographs selected.
This collection of 1173 photographs of glaciers in and around the Lake Clark National Park and Preserve in Alaska was compiled by Jacob Zanon while he was a Natural Resource Specialist Intern in the GeoSpatial Services Department at Saint Mary's University, MN. The collection is comprised of many images of glaciers inside the park and preserve taken from both the air and the ground from 1987 through 1990 and in 2004 and 2007. J. Zanon collected all of the digital images and created the metadata for them. Once the images and metadata were transferred to NSIDC, they were reviewed for quality and accuracy by Ladina Gaus while she was interning at NSIDC as a graduate student in the Geography Department at the University of Zurich, Switzerland. She checked that all photographs, which show the same glacier, have the same coordinates because the coordinates in the metadata describes the location of the glacier and not the position where the photographer stood. Google Earth was very helpful for this analysis. Because most of the photos did not provide a glacier name, she attempted to determine them. To this end, she uploaded a Microsoft Excel file with the photo IDs and the corresponding coordinates as a shape file into QGIS and then merged it, by location, with the corresponding outlines from the GLIMS database. Additionally, she consulted maps and a satellite image atlas of Alaska by Williams and Ferrigno (2008). She was able to determine some glacier names, however, most glaciers in Alaska are unnamed.
The Glacier Photograph Collection was initially created in 2002 with a little over 1,000 photographs. It has since grown to comprise over 16,600 images as of August 2016. Table 4 provides a brief history of the development of the collection.

Waldrop collected photographs of Arapaho Glacier taken in the early 1900s by Junius Henderson, first curator of the CU Boulder Museum. Using repeat photography techniques, Waldrop recreated Henderson's photographs for his thesis research completed in 1962.|
|June 2008||Also in June 2008, the first batch of aerial photographs taken by Austin Post and members of the USGS Ice and Climate Project (ICP) were added to the collection. This collection was digitized from a 35 mm roll of microfilm and consists of approximately 13,600 images. The vast majority of the images were taken by Post and are thus described but others were taken by members of the ICP for USGS. For more information about the ICP collection contact the GeoData Center of the Geophysical Institute at the University of Alaska, Fairbanks where the original negatives are housed.|
|June 2010||NASA Astronaut Glacier Photographs special collection created with 500 photos.|
|March 2011||Antarctica Dry Valleys Glacier Photographs special collection created with 24 photos.|
|May 2015||WGMS Glacier Photographs special collection added with 1192 photos.|
|August 2016||Lake Clark National Park and Preserve Collection added with 1173 photos.|
The photographs that make up this collection were taken with a range of cameras from mid-1800's box cameras to 21st century digital SLRs depending on the age of the photo. The cameras were located on the ground, on aircraft, on the U.S. Space Shuttle Endeavor, and on the International Space Station.

The NOAA Climate Database Modernization Program (CDPM) provided funding and programmatic oversight for digitizing many of the photos in the Glacier Photograph Collection. NOAA’s Joseph Elms managed the program. The photos were digitized at CDMP Corporate Partner LASON Corporation, Beltsville, MD, under the direction of John Jacobs. Teresa Mullins, NSIDC Librarian from October 1999 through June 2004, initiated the digitization project, wrote the statement of work with imaging requirements for digitizing prints, and compiled metadata for the first set of images digitized. She also researched NSIDC's analog collection to provide background on W. O. Field's contribution of glacier photograph prints to the WDC for Glaciology, Boulder.
Allaina Wallace, NSIDC Data Archivist and Librarian from 2004 to 2014, curated the collection, overseeing the addition of thousands of scanned photographs through further work with the CDMP program and with the aid of a series of interns and student volunteers.
NSIDC glaciologist Dr. Richard Armstrong assisted in documenting the collection and with selecting photographs of greatest scientific interest for digitization. USGS glaciologist Dr. Bruce F. Molnia serves as an advisor to the project and assisted with the evaluation and documentation of our analog glacier photograph collection. Dr. Molnia also contributed repeat photographs.
Sincere thanks go to Mylène Jacquemart and Michael Zemp of WGMS for initiating and leading the 2015 update work. Ann Windnagel, Jon Davis, and Daniel Crumly carried out the work at NSIDC.
The NOAA@NSIDC team maintains this product at NSIDC. This work is supported by funding from NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) and NOAA National Centers for Environmental Information (NCEI).
