TY - CONF TI - Retrieval of optical properties of cloud layers from transmitted solar radiance and irradiance data AU - Varotsos, C AU - Melnikova, IN AU - Domnin, PI AU - Pivovarov, SS PY - 1997 SP - 77-80 PB - SPIE - INT SOC OPTICAL ENGINEERING T2 - 23RD EUROPEAN MEETING ON ATMOSPHERIC STUDIES BY OPTICAL METHODS TODO - 10.1117/12.284762 TODO - strati clouds; solar radiation; radiance; irradiance; anomalous absorption; scattering; optical thickness; single scattering albedo TODO - The strict analytical formulas are derived from asymptotic formulas of the radiative transfer theory for determination of optical thickness and single scattering albedo on base of measurements reflected or transmitted solar radiance or irradiance in strati clouds. The detailed error analysis of the methodology proposed is carried out. The formulas obtained are applied for interpretation of the spectral data of ground-based measurements at the drifting Arctic station in 1979. The values of optical thickness and single scattering albedo are obtained and reveal the apparent spectral dependency. ER -
