Popis: The split-window method is used to retrieve land surface temperature from the multispectral measurements of the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA polar orbiting satellite. Several split-window equations have been developed to retrieve the land surface temperature for a constant satellite zenith angle. A new split-window equation has been developed, in which the coefficients of the equation depend on the viewing angle. An accurate radiative transfer model developed by P.Schlussel has been used to study the angular effect in the NOAA-11 and 14 AVHRR brightness temperatures. The angular dependence of the split-window equation has been determined from regression analysis of radiative transfer simulations. The results showed that the dependence of the temperature from the viewing angle was eliminated in most cases.
