• On Wednesday, September 24 from 9:00 a.m. to 1:30 p.m. (US Mountain Time), this data set may not be available in the legacy data archive due to a planned system maintenance. Earthdata Cloud access will remain available for data sets that have migrated. Users of the SMAP near real-time products should use the NASA LANCE HTTPS File System for data access.

  • The NSIDC DAAC is retiring access to its legacy, on-premises data archive and transitioning to the NASA Earthdata Cloud as the primary data archive. View planned retirement dates here.

ATLAS/ICESat-2 L3B Monthly Gridded Atmosphere, Version 3
Data set id:
ATL17
DOI: 10.5067/ATLAS/ATL17.003
There is a more recent version of these data.
Version Summary
Changes for this version include:

  • The blowing snow frequency parameter based on the 1 Hz average backscatter data was renamed to low-rate blowing snow frequency and a high-rate blowing snow frequency parameter generated from 25 Hz backscatter data was added.

  • The grid size for the weekly product (ATL16) changed from 2° x 2° to a 3° latitude x 3° longitude for the global coverage and to a 1° latitude x 3° longitude for the polar coverage.

  • The grid size for the monthly product (ATL17) changed from 1° x 1° to a 1° latitude x 1° longitude for the global coverage and to a 0.5° latitude x 1.5° longitude for the polar coverage.

  • Gridded parameter minimum, maximum, and standard deviation values in addition to the average are written on each image and included in the data product.
