SEA SURFACE TEMPERATURE PRODUCTS AND RESEARCH ASSOCIATED WITH GHRSST

摘要

GHRSST serves its user community through the specification of operational Sea Surface Temperature (SST) products (Level 2, Level 3 and Level 4) based on international consensus. Providers of SST data from individual satellites create and deliver GHRSSTcompliant near-real time products to a global GHRSST data assembly centre and a long-term stewardship facility. The GHRSST-compliant data include error estimates and supporting data for interpretation. Groups organised within GHRSST perform research on issues relevant to applying SST for air-sea exchange, for instance the Diurnal Variability Working Group (DVWG) analyses the evolution of the skin temperature. Other GHRSST groups concentrate on improving the SST estimate (Estimation and Retrievals Working Group EARWiG) and on improving the error characterization, (Satellite SST Validation Group, STVAL) and on improving the methods for SST analysis (Inter-Comparison Technical Advisory Group, ICTAG). In this presentation we cover the data products and the scientific activities associated with GHRSST which might be relevant for investigating oceanatmosphere interactions.
