SEA-SURFACE TEMPERATURE AND BOUNDARY-LAYER FLUXES FROM ERS-1 ATSR DATA/

Dual angle and multi-spectral observations from ERS-1 ATSR can be util ized for corrections for sea surface temperature retrieval and to esti mate the moisture and temperature structure of the lower boundary laye r. The SST has been retrieved to a good level of satisfaction (0.5 K r ms) while the surface humidity retrieved have been found to an accurac y of 10%. The feasibility of estimating the surface-air exchanges over the oceans has also been confirmed. Latent heat fluxes(LHF) for a lim ited region are derived using bulk aerodynamic formula. The comparison between satellite derived and ship derived LHF yields an RMS error of 34 watts m(-2).
