Short Name:

ASTER L2 Surface Reflectance VNIR and Crosstalk Corrected SWIR V003

The ASTER Surface Reflectance VNIR and Crosstalk Corrected SWIR (AST_07XT) dataset ( contains measures of the fraction of incoming solar radiation reflected from the Earth’s surface to the ASTER instrument corrected for atmospheric effects and viewing geometry for both the Visible and Near Infrared (VNIR) and Shortwave Infrared (SWIR) sensors. Each product delivery includes two Hierarchical Data Format - Earth Observing System (HDF-EOS) files: one for the VNIR, and the other for the SWIR. They are distinguished from one another by a one-second difference in the production time that appears as part of the file name. Both the VNIR and SWIR data are atmospherically corrected and are generated using the bands of the corresponding (ASTER L1B) ( image. AST_07XT is a multi-file product that contains atmospherically corrected data for both the VNIR and SWIR sensors. ASTER Level 2 data requests for observations that occurred after May 27, 2020 will resort back to using the climatology ozone input.
