Physical Deterministic Sea Surface Temperature for dynamic region of California Coast

The methodology of physical deterministic sea surface temperature (PDSST) retrieval suite has been well-established in numerous publications for nighttime measurements. Previous studies were made only for nighttime conditions at in situ matchup location, this work is focused on the various problems of daytime SST retrieval using shortwave infrared (SWIR) channels, extension into full-swath processing capability, and comparison against recently reprocessed L2P SST from PO.DAAC. Although operational implementation of PDSST in MODIS is still under development, some granules of SST retrieval for MODIS-AQUA have been examined and comparative results against NASA operational MODIS SST product (PO.DAAC) are highly promising. For illustration, the swath retrieval results for daytime granule from December 2017 for the dynamic area of California coast are chosen and compared with currently distributed NASA operational MODIS-AQUA SST. The information gain is ~twenty times higher for PDSST for such locations.
