Measurements of up and down welling radiance are used for the determination of sea surface reflectivity (SSR) and sea surface temperature (SST). The radiance measurements are performed with the "Ocean Atmosphere Sounding Interferometer System" (OASIS) which is operated at a spectral resolution of about 1 cm(-1). The SSR is estimated in IR window regions from 800 to 1200 and 2095 to 2160 cm(-1). During a field campaign the SSR is measured from an ocean pier at the baltic sea. The comparison of measured and calculated SST suggest that from several available sets of refractive indices the one published by Bertie and Lan (1996) including a correction for sea water from Friedmann (1969) represents the measurement best.
