Filter by:
Airborne Snow Observatory (ASO)
Snow depth and snow water equivalent (SWE) data, and lidar point cloud terrain models derived from airborne remote sensing campaigns conducted over the western United States from 2013 to 2019.
AMSR Unified
Passive microwave data products on snow, sea ice, soil moisture, vegetation water content, and brightness temperature. Data have a global coverage and are derived from NASA's AMSR2 and AMSR-E satellite instruments.
Passive microwave data products from June 2002 through early October 2011 related to sea ice concentration, sea ice motion, sea surface temperature, snow depth, snow water equivalent, soil moisture, wind speed, water vapor, precipitation, and other parameters.
Passive microwave measurements from early 2003 through October 24, 2003. The data include sensor counts and brightness temperature.
Global gridded soil moisture data and additional polar gridded products spanning August 2011 to June 2015.
Arctic Ice Dynamics Joint Experiment (AIDJEX)
Meteorological, oceanographic, and sea ice data products related to the 1970s' AIDJEX program
Cold Land Processes Field Experiment (CLPX)
Brightness temperature, albedo, visible and infrared imagery, snow characteristics, vegetation, soil moisture, and meteorology data of the Central Rocky Mountains of Colorado.
Environmental Working Group Arctic Atlases (EWG)
Meteorological, oceanographic, snow, and sea ice data products resulting from U.S.-Russian collaboration in Arctic research. Observations range from the 1950s through the mid-1990s, and include previously classified observations.
GLIMS: Global Land Ice Measurements from Space
Glacier data from the GLIMS initiative, an international project to inventory the world’s glaciers, and to create a comprehensive, global database of land ice through repeat surveys.
High Mountain Asia (HMA)
Snow and ice data from a region that stretches across five mountain ranges, including the Himalaya and Hindu Kush. The region covers parts of China, Afghanistan, Nepal, India, Pakistan, Bhutan, Kazakhstan, Uzbekistan, Kyrgyzstan, and Tajikistan.
Data from the ATLAS instrument used on NASA's ICESat-2 satellite mission. Data products in this collection describe elevations of sea ice, land ice, forest canopies, water height, urban areas, and more. Data observations span from late 2018 to present.  
Data from the GLAS instrument on the ICESat satellite mission which collected data from 2003 to early 2010. Data products describe elevations of ice sheets, glaciers, and sea ice, as well as height profiles of clouds and aerosols.
LVIS: NASA Land, Vegetation and Ice Sensor Facility
LVIS is an airborne, wide-swath imaging laser altimeter system that is flown over target areas to collect data on surface topography and three-dimensional structure. Available data products come from missions over polar regions, and in parts of North America, Central America, and Africa.
Data products derived from satellite data that encompass snow, sea ice, glaciers, ice sheets, ice shelves, and freeze/thaw conditions, snow, and brightness temperatures.
Snow cover and sea ice data products derived from Moderate Resolution Imaging Spectroradiometers on both the Aqua and Terra satellites.
This collection includes a diverse suite of data products, ranging from snow depth measurements and temperature readings to radar reflectivity, collected during through airborne and ground campaigns in forested regions of the western United States.
Nimbus Data Rescue Project
This data collection includes satellite images from the 1960s, 1970s, and early 1980s. Composites of visible imagery and of infrared data show sea ice conditions and can be used to study how sea ice has changed over several decades.
Operation IceBridge
These data describe annual changes in ice surface elevation, topography of bedrock under ice sheets, glacier and ice shelf grounding lines, snow and ice thickness, sea ice distribution, sea ice freeboard, ice temperature, and meteorological observations.
Includes near-global passive microwave data from 1978 to present. In addition to sea ice concentration and extent, the SMMR data collection includes data on sea surface temperatures, wind stress, snow cover, rainfall rates, and more, and the SSM/I and SSMIS collection includes data relating to brightness temperature, snow-covered area, snow cover, snow water equivalent, snow melt, sea ice motion, sea ice age, and more.
Soil Moisture Active Passive Data (SMAP)
Data products derived from an L-band radiometer and high-resolution L-band radar instrument used on the SMAP satellite mission and include measurements of surface soil moisture conditions everywhere on Earth.
Snow cover, sea ice cover, and sea ice temperature data collected by the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor. The VIIRS instrument, a scanning radiometer, acquires visible and infrared imagery and radiometric measurements of Earth’s landmasses and oceans. Data coverage from VIIRS began in 2012 and runs to the present day.
