A modification has been incorporated within the processing of the ASTER L1T data product (AST_L1T) for correcting zero-filled scans that appear in certain thermal infrared (TIR) night data acquisitions. This correction has been implemented in the processing of newly acquired AST L1T data beginning with date May 10, 2017. Reprocessing of the historical data will begin with present day 2017 and work in reverse chronological order for the remainder of the archive. Further information can be found in the ASTER L1T User Advisory.
