The IceBridge ATM L1B Elevation and Return Strength, Version 2 data set has been updated from 17 April 2019 through 16 May 2019 to include data from the 2019 Arctic campaign at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains spot elevation measurements of Arctic and Antarctic sea ice, and Greenland, Antarctic Peninsula, and West Antarctic region ice surface acquired using the NASA Airborne Topographic Mapper (ATM) instrumentation.
New data access options are available for the MEaSUREs Greenland Annual Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1 data set, accessible from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The data access location for this data set has changed. Users accessing this data set through a script will need to update accordingly.
The ASO L4 Lidar Point Cloud Digital Terrain Model 3m UTM Grid, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set provides 3 m gridded, bare-earth elevations (excluding trees) that are used as the baseline for the Airborne Snow Observatory (ASO) snow-on products. The data were collected during snow-free conditions as part of the NASA/JPL ASO aircraft survey campaigns.

NOAA@NSIDC is pleased to announce the release of the Daily Great Lakes Ice Concentration, 1973 Onward data set. This data set consists of gridded lake ice concentration for the Laurentian Great Lakes from the NOAA@NSIDC Great Lakes Environmental Research Laboratory (GLERL). The data are provided as ASCII text files along with corresponding browse image files in JPEG format beginning in 1973 and going through the present. GLERL produces this product to help researchers and others understand how, when, and where lake ice forms and breaks up.
Multiple VIIRS snow cover data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been reprocessed due to an error in the planetary ephemeris data. This resulted in the use of incorrect solar and lunar vectors for the period 16 Jan. 2020 00:00:00 - 17 Jan 2020 10:00:00. The affected files were reprocessed and redelivered on 6 March 2020.
