ATL16

ATLAS/ICESat-2 L3B Weekly Gridded Atmosphere, Version 3

This product reports weekly global cloud fraction, total column optical depth over the oceans, polar cloud fraction, blowing snow frequency, apparent surface reflectivity, and ground detection frequency.

This is the most 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.
