Paper Abstract

12 MODIS (Moderate Resolution Imaging Spectroradiometer) was launched on board the NASA's Terra Earth Observing System (EOS AM-1) Satellite on December 18, 1999. We propose in this work operative split-window algorithms for retrieving sea surface temperature (SST) and land surface temperature (LST) using MODIS data. In order to attain our goal, the MODTRAN 3.5 radiative transfer code was used to predict radiances for MODIS channels 31 and 32. To analyze atmospheric effects, a set of radiosoundings was used to cover the variability of surface temperature and water vapor concentration on a worldwide scale. These simulated data were split into two sets which have very similar distributions in space and time. The first one was used to fit the coefficients of the algorithms for retrieving both SST and LST, while the second one was used to test the fitted coefficients. Later, a sensibility study, including the effects of noise, emissivity and water vapor content uncertainties, has been done using the error theory.
