Version Summary
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.
Overview
As of 18 August 2022, this data set is retired and no longer available for download. Per our agreement with the data provider, NSIDC only archives the most recent version of each of the ICESat-2 standard products and the version that preceded it.
