Derivation of remote sensing reflectance of Baltic waters from above-surface measurements

Olszewski J., Darecki M.

No. 41 (1)

99-111

It has been shown experimentally that the remote sensing reflectance can be readily calculated from the total remote sensing reflectance, provided certain external conditions are fulfilled. The first condition concerns the solar zenith distance, which should be limited to the 35–70o range (suitable to the Baltic region). The second condition refers to the sea state, which should display no foam and no vertically directed solar glitter. Under such circumstances some simplifying assumptions were possible, which permitted a proper algorithm, in the form of a linear function, to be worked out. Coefficients of the function are tabled for 10 discrete wavelengths (widened SeaWiFS standard), and are also given analytically as linear functions of the wavelength.
