Discontinuation of Aura OMI as an Ancillary Ozone Input for ASTER Products

The production of AURA Ozone Monitoring Instrument (OMI) data aboard NASA’s Aura satellite has been discontinued as of October 6, 2023. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on-demand higher level product orders for ASTER acquisitions after October 06, 2023, will fall back to climatology ozone inputs. Aura OMI ozone inputs will continue to be available for on-demand product orders for ASTER scenes within the acquisition range: December 2, 2004 – October 6, 2023. The following list of ASTER V003 products are impacted:

• 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)
