NEW AUSTRALIAN HIGH RESOLUTION AVHRR SST PRODUCTS FROM THE INTEGRATED MARINE OBSERVING SYSTEM

摘要

The Australian Bureau of Meteorology (the Bureau) is producing 1 km resolution sea surface temperature (SST) products in real time from data from the Advanced Very High Resolution Radiometer (AVHRR) sensors on board NOAA polar orbiter platforms received at the Bureau's satellite reception facilities. As part of the Australian Integrated Marine Observing System (EVfOS: the Bureau has recently upgraded its SST processing system to comply with the GHRSST (Group for High Resolution SST) Data Processing Specification v2.0 (Casey et al., 2010a) and up-to-date processing that meets or exceeds worlds best practice. The significant components include the use of regional rather than global buoy SSTs for satellite SST calibration, noise resistant methods of SST coefficient estimation, the development of a match-up database (MDB), calculation of single sensor error statistics (SSES), an improvement in cloud identification, and the generation and distribution of SST products in GHRSST L2P and L3C formats.
