ASTER L2 Surface Reflectance VNIR and Crosstalk Corrected SWIR V003
The ASTER Surface Reflectance VNIR and Crosstalk Corrected SWIR (AST_07XT) dataset (https://lpdaac.usgs.gov/documents/618/ASTER_Earthdata_Search_Order_Instructions.pdf) 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) (https://doi.org/10.5067/ASTER/AST_L1B.003) 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. Additional information can be found in the ASTER L2 Processing Options Update (https://lpdaac.usgs.gov/news/aster-l2-processing-options-update/).

- Quality Users are advised that ASTER SWIR data acquired from late April 2008 to the present exhibit anomalous saturation of values and anomalous striping. This effect is also present for some prior acquisition periods. Please refer to the ASTER SWIR User Advisory Document (https://lpdaac.usgs.gov/documents/217/ASTER_SWIR_User_Advisory_July_18_08.pdf) for more details.
