SnowEx 2023 - October 2022 Alaska IOP snow pit measurements

Watch for preliminary releases to be posted here. 





SnowEx Campaign data is publicly available through the NASA DAAC at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. Data are available to anyone at no cost, as is the case with all NASA data. Available data products are searchable by campaign year. You can also browse recently published data by visiting The Drift, a product from NSIDC to share news and tips with data users.




NASA SnowEx InSAR L-band data are hosted at ASF through the Data Search Vertex. Information about the NASA JPL UAVSAR mission can be found by visiting the mission webpage

Airborne Snow Observatory

The NASA Airborne Snow Observatory (ASO) data will be archived and distributed by NSIDC DAAC. The data, derived from a coupled imaging spectrometer and lidar system will include snow depth, snow water equivalent (SWE), and albedo collected during airborne campaigns in the western United States and beyond.

MODIS/VIIRS Snow/Sea Ice Data

A suite of MODerate-resolution Imaging Spectroradiometer (MODIS) snow and sea ice products, developed at NASA / GSFC, are available through the National Snow and Ice Data Center.  The suite of products consists of global daily, 8-day maximum and monthly snow cover at 500-m and 0.5-km spatial resolution; daily cloud-gap-filled snow cover; daily snow albedo at 500-m resolution; and daily sea ice extent and ice-surface temperature (IST).  Nearly-identical product suites are available both from the Terra and Aqua satellites in HDF-EOS format.

A special Terra MODIS daily product of the Greenland Ice Sheet is also available.  This product consists of layers of ice-surface temperature, albedo and water vapor for the Greenland Ice Sheet (2000 - 2016) at a spatial resolution of 0.78 km, on a polar stereographic grid in NetCDF format.

Visible Infrared Imager Radiometer Suite (VIIRS) global, daily snow-cover maps,developed at NASA / GSFC, are archived and available through the National Snow and Ice Data Center.



The SNOwpackTELemetryNetwork (SNOTEL), which is an automated system of snowpack and related climate sensors operated by the Natural Resources Conservation Service (NRCS) of the United States Department of Agriculture in the Western United States, collects snow data that include snow water equivalent, accumulated precipitation, and air temperature. In addition, some sites include a measure of snow depth, soil moisture and temperature, wind speed, solar radiation, humidity, and atmospheric pressure. These data are used to forecast yearly water supplies, predict floods, and for general climate research. SNOTEL snow course data and products are available on this site.

Snow Depth on Sea Ice

Snow depth on sea ice retrievals from the Operation IceBridge mission are archived and distributed by the NSIDC DAAC. The data also include associated parameters such as surface roughness, sea ice freeboard, and sea ice thickness.
