Data set update: IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles

The IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles, Version 2 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include data for the Spring 2018 Greenland campaign. This data set contains radar echograms taken over Greenland and Antarctica using the Center for Remote Sensing of Ice Sheets (CReSIS) Accumulation Radar instrument. The data were collected as part of Operation IceBridge funded campaigns.

Upcoming Earthdata Webinar – NASA Operation IceBridge: Come Discover a Decade of Polar Data

NASA’s Operation IceBridge airborne mission has flown over 700 flights through some of the most stunning regions of the Arctic and Antarctic. Join us to learn how to discover and access data that “bridges” the gap between the ICESat and ICESat-2 missions.

When: Wednesday, July 25, 2018 at 2pm EDT (UTC/GMT-4).

Zoom In: Geolocating IceBridge Data

In 2009, NASA initiated Operation IceBridge, flying airborne missions to pinch hit for the ICESat satellites’ expected gap from 2009 to 2016. The airborne platform and the broad suite of instrumentation allow for the collection of high resolution snow and ice data from targeted areas of scientific interest. The downside is that the total area covered is not nearly as vast as what a satellite typically covers.

The resources listed below allow you to zoom in on the specific areas of the Earth where IceBridge data were collected. Many of these resources also provide a handy way to access the IceBridge data of your choice.

IceBridge Data Portal

* Download simplified flight lines and view them in Google Earth or your favorite Earth browser

* Note: While these represent the majority of IceBridge flights, they will not include campaigns flown without the ATM instrument

Earthdata Search

The new Earthdata Search


NASA Reverb or the new Earthdata Search tool

* See the locations of flight segments associated with each data file on a map

* Search for and download just the data files that meet your criteria

* Note: Many but not all IceBridge data sets are available for visualization and download with these tools

Geolocation coordinates in the data files

* Those who have already selected and downloaded data files may start analyzing the individual measurements based on the Latitude and Longitude coordinates contained therein

* To the right is an example of a data table taken from the IceBridge MCoRDS L2 Ice Thickness data set

Instrument position data

* Some researchers may need instrument position information, which may include altitude, velocity, roll, and pitch in addition to coordinates

* Separate data sets with this information are available for the DMS Camera and the LVIS Instrument

* For some other instruments, this information is included within the Level 0 data set for the instrument. To easily browse the holdings of IceBridge data sets, see the NSIDC Data Search tool

Those of you interested in NASA Operation IceBridge data may benefit from taking a moment to sit back and watch this video recording of a webinar overviewing the IceBridge mission and how to use the data portal. Steve Tanner, manager of the IceBridge data archive at NSIDC, guides us through a brief introduction to the IceBridge airborne mission and takes us, step by step, through the process of searching for and downloading IceBridge data. The video is from a live webinar hosted by NASA EOSDIS.

NASA Operation IceBridge data is of particular interest to researchers looking for remote sensing measurements over the polar regions from 2009 to the present. This airborne mission is designed to work in conjunction with satellite missions such as ICESat-1, CryoSat, and the upcoming ICESat-2.

Recent enhancements to the NASA IceBridge Data Portal

The NASA IceBridge Project is comprised of airborne data over the most dynamic areas of the Arctic, Greenland, Alaska and Antarctica. The data gathered by this project are unique in that they are spatially referenced by flight lines, flights are flown during approximately 3-month campaigns, and data are collected by a wide variety of instrumentation.

The NASA IceBridge Data Portal provides a single location from which one can get an overview of all the IceBridge data sets. It allows for map-based visualization of the flight paths via polar views of the Northern and Southern Hemispheres.  Using a variety of filters and image overlays, one can visualize, search and download IceBridge data campaigns. NSIDC recently added some new capabilities to the IceBridge Data Portal. These new features include:

– A simpler display which allows users to hide and move informational windows

– The ability to filter results by selecting one or more instruments

– A tar-on-the-fly option for downloading complete directories of data at once

– New map layers for enhanced visualization including:

  • Mosaic of Greenland (MOG)
  • Shaded Relief DEM
  • MEaSUREs Velocity Map
  • Mosaic of Antarctica (MOA)
  • Antarctic Bedrock DEM
  • Radarsat Antarctic Mapping Project (RAMP)
