New ASTER Radiometric Calibration Coefficients Library

On June 23, 2021, ASTER Level 1A Reconstructed Unprocessed Instrument (AST_L1A) Product Generation Executables (PGE) were updated to allow the application of radiometric calibration coefficients (RCC) from Version 4 to 5. This change will only impact Visible and Near Infrared (VNIR) bands 1-3 for day-time scenes. The citation for the journal article describing the details for RCC V5 is listed below.

Tsuchida, S., Yamamoto, H., Kouyama, T., Obata, K., Sakuma, F., Tachikawa, T., Kamei, A., Arai, K., Czapla-Myers, J.S., Biggar, S.F., and Thome, K.J., 2020, Radiometric Degradation Curves for the ASTER VNIR Processing Using Vicarious and Lunar Calibrations: Remote Sensing, v. 12, no. 3, at https://doi.org/10.3390/rs12030427.

The following higher level products derived from ASTER L1A will be generated with this updated data input.

• ASTER Level 1B Data Set Registered Radiance at the Sensor (AST_L1B)
• ASTER L2 Surface Emissivity (AST_05)
• ASTER L2 Surface Reflectance VNIR and SWIR (AST_07)
• ASTER L2 Surface Reflectance SWIR Crosstalk-Corrected (AST_07XT)
• ASTER L2 Surface Kinetic Temperature (AST_08)
• ASTER L2 Surface Radiance VNIR and SWIR (AST_09)
• ASTER L2 Surface Radiance SWIR Crosstalk-Corrected (AST_09XT)
• ASTER L2 Surface Radiance TIR (AST_09T)
• ASTER Digital Elevation Model (AST14DEM)
• ASTER Digital Elevation Model and Orthorectified Registered Radiance at the Sensor (AST14DMO)
