BLUElink Global Australian Multi-Sensor SST Analysis (GAMSSA), daily, 1/4 degree resolution for 2009-11-01 (NCEI Accession 0060146)

browse graphicGraphic not available.
The GAMSSA v1.0 system blends NAVOCEANO's GAC 9.9 km x 4.4 km resolution AVHRR L2P SST1m data (NOAA-17, NOAA-18 and METOP-A), European Space Agency's 0.17 AATSR skin SST Meteo Product (EnviSat), Remote Sensing System's 25 km resolution AMSR-E L2P sub-skin SSTs (Aqua) and in situ bulk SSTs from the GTS. In order to produce a foundation SST estimate, the AATSR skin SST data stream is converted to foundation SST using the Donlon et al. (2002) skin to foundation temperature conversion algorithms. These empirically-derived algorithms apply a small correction for the cool-skin effect depending on surface wind speed, and filter out SST values suspected to be affected by diurnal warming by excluding cases which have experienced recent surface wind speeds of below 6 ms-1 during the day and less than 2 ms-1 during the night. Wind data used are the 0.75 horizontal resolution, 3-hourly, instantaneous 10 m winds derived from the BoM 60 level, Global Area Prediction System (GASP) NWP forecasts. The remaining satellite and in situ sub-skin and bulk SST data streams are similarly filtered to remove suspected diurnal warming events using calculated times for sunrise and sunset at the measurement location, GASP forecast winds and the same wind speed thresholds as applied to the AATSR data.
