Van de site
The web page shows the sea surface temperature (SST) and anomalies derived from infrared measurements from the polar orbiting satellites. One interpolated field is constructed daily. Only nighttime SST observations are used for the interpolation because these are more representative of the temperature in the upper meters of the water column. One image per day is shown for the last 30 days.
The SST anomalies have been calculated with respect to a mean, which has been derived from observations from 1985 to 2001. They are SST climatology monthly values from the Pathfinder project and temporal interpolation is used between the two nearest months to obtain this days SST climatology. For more information on the monthly climatology, see: www.nodc.noaa.gov/sog/pathfinder4km/
