Abstract

Radiation thermometry is used extensively in Sea Surface Temperature (SST) measurements, yet it suffers from a serous drawback: It requires knowledge of the emissivity of the surface whose temperature is being measured i.e. the sea surface. The emissivity of the emitting surface not only determines the radiance emitted by the surface but also governs the level of background radiation reflected by the same surface. Furthermore, the temperature of the top 10 µm thick layer of the sea surface which is measured using radiation thermometry in the 8 µm to 12 µm wavelength range differs significantly from the bulk temperature of the sea water. The author proposes a novel method of measuring the temperature of the top 10 µm thick film of the surface of the sea using dependence of the fluorescence characteristics of fluorophors on temperature. This method is completely different from radiation thermometry and provides a more direct method for the validation of SST measurements made using radiation thermometry.
