MethodologyNOAA/NESDIS has been producing sea surface temperatures from satellite data since 1972. Monitoring of SST from earth-orbiting infrared radiometers has had a wide impact on oceanographic science. Beginning in mid-1996, a new satellite-only climatology (for 1985-1993) became available and made it possible to generate more accurate SST anomaly products from the operational 50-km daily SST field. The NOAA/NESDIS operational SSTs are provided twice a week in near real-time and use both day and night retrievals. Since the satellite-only SST monthly mean climatology is derived only from nighttime SST observations to eliminate the diurnal variation caused by diurnal solar heating at the sea surface (primarily at the "skin" interface, 10-20 æm), only nighttime SST analyses are used to ensure consistency between the satellite SST observations and the climatology.`http://www.ospdp.noaa.gov/PSB/EPS/SST/methodology.html DatasetsReferences
