Abstract

Long-term surveillance of coastal zones like the German Bight with airborne laser fluorosensors have shown the capability of active remote sensing to investigate various oceanic parameters, such as dissolved organic matter (gelbstoff) or chlorophyll in algae. Recently the feasibility of a spaceborne laser fluorosensor for large-scale monitoring of water-column parameters has met increasing interest. Complementary to passive remote sensing instruments, like SeaWifs or OCTS, active remote sensing promises to provide a powerful tool for detection of substances which are otherwise hardly detectable, using inherent molecular fluorescence at specific wavelengths. The feasibility of such measurements using platforms at altitudes of up to 800 km is studied. This would allow the instrument to be operated as an attachment to atmospheric lidars. A simulation of radiative transfer in a cloudless and horizontally stratified atmosphere is presented, with particular emphasis on wavelengths which are relevant for hydrographic measurements. Results of this simulation are presented, especially the geometrical aspects of radiative transfer through the atmosphere, optimization of lidar parameters and effects of dispersion.
