ASTER Scenes Reassessed for Cloud Cover

Sep 05, 2018

All ASTER Level 1A and Level 1T scenes have been reassessed for cloud cover using the MODIS Version 6.1 cloud mask. As a result, about 1% of all ASTER Level-1A and Level-1T scenes show a cloud-coverage change of 25% or larger. Scenes acquired in high and low latitude zones show the most significant changes.

The data are available for download through NASA Earthdata Search.
