SPECIAL MESSAGE:

On Tuesday, December 6 at approximately 11 a.m.EST (1500 UTC), a planned web system upgrade will be performed. This will result in a brief delay of data on the GOES, SPSD and OSPO web sites for up to two hours. Some data will take longer to recover. Please see the related message, which has additional details, and watch http://www.ssd.noaa.gov/PS/SATS/messages.html for additional information.

Sea Surface Temperature (SST)

(SST is defined as the skin temperature of the ocean surface water.)


    Operational Products
CoastWatch SST CoastWatch sea surface temperatures are derived from a set of multi-channel atmospherically corrected algorithms using brightness temperatures from channels 3, 4 and 5, albedo information from channels 1 and 2 and satellite and solar zenith angles.

Sample Sea Surface Temperature Image


POES Resolution: 1 or 4 Km Frequency: Varies by Satellite
SST Anomaly Charts The SST anomaly field (degrees C) is the difference between the 50 km nighttime-only SST and the nighttime-only monthly mean SST climatology. The climatology is based on nighttime observations from 1984-1993, with SST observations from the years 1991 and 1992 omitted due to aerosol contamination from the eruption Mt. Pinatubo in June of 1991.

POES Resolution: 50 Km Frequency: Twice Weekly
SST Contour Charts Graphical depiction of Sea Surface Temperature gridded products. Contour charts are used to depict both global and regional SST values in various grid spacing.

SST Nighttime Field Image Charts The operational night-only SST analysis is at a resolution of 50 km and is used to produce the SST anomaly charts.

POES Resolution: 50 Km Frequency: Twice Weekly
SST Monthly Mean A satellite-only monthly mean time series of SST at 36 km resolution has been provided by Al Strong (ORA/ORAD) based on only nighttime SST satellite observations. These datasets, based on NESDIS's AVHRR data, have been accumulated into weekly means (U of Miami - RSMAS) and provided to NASA-JPL for distribution. Some SST monthly means are omitted due to contamination by volcanic aerosols (1981-1983 and some of 1991-1992 due to the eruption of Mt. Pinatubo).

CoastWatch SST Color enhanced versions of Sea Surface Temperatures from GOES Imager. The GOES-11 and 12 imagers observe both northern and southern hemisphere every half an hour. These 5-band (0.6, 3.9, 6.7, 10.7, 12 or 13.3 micron) and 4-band (0.6, 3.9, 6.7, 10.7. or 13.3 micron) images are processed to retrieve SST retrievals at 4-km resolution. The infrared channels determine the SST, and all channels (except the 6.7 and 13.3 km) determine the cloud contamination. These retrievals are remapped, averaged and composited hourly and made available for users to access.
