Abstract : A satellite method for measuring sea surface temperature uses simultaneous coverage by two satellites in the same spectral window plus a simplified atmospheric radiative transfer model. A geostationary satellite and any polar orbiting satellite provide nearly coincident infrared imagery of a given area with points of equal and unequal observation angles. The calibration curve of the data for one satellite is adjusted to match the temperatures of the better calibrated satellite data along the equal angle points. A difference image is obtained from the resulting two satellite temperature images. The difference image together with the two observation angles and the temperature of the more accurate satellite radiometer are input to a suitable atmospheric model to obtain sea surface temperature at each point in the study area. The result is an accurate sea surface temperature for each point within a given area which is corrected for a spatially variant atmosphere.
