GOES Sea Surface Temperature

NOAA CoastWatch provides sea surface temperature (SST) products derived from NOAA's Geostationary Operational Environmental Satellites (GOES). These products are created by combining three separate images, each created 1-hour apart and retaining the most recent temperature value. Therefore, the near real-time images are updated every three hours.

GOES SST is determined by applying a regression equation to measurements from the infrared channels. Multispectral information for channels 1, 2, 4 and 5 are used to identify clouds, wind effects, and other factors that may affect the values. Each GOES satellite has its own SST regression equation. GOES SST spatial resolution is nominally 4 km.

Validation of these algorithms was performed by comparing GOES-SST retrievals against a quality controlled data set from global drifting and moored buoy SST measurements. Comparisons were performed within one hour and 5km of each other. Results show that the GOES-Buoy SST comparison has a bias of 0.5 degree C and a standard deviation less than 1 degree C. Validation results are available for 2013 and earlier.
