All Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Level 1A and Level 1T scenes have been reassessed for cloud cover using the Moderate Resolution Imaging Spectroradiometer (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.
