Analysis of cloud top height and cloud coverage from satellites using the O2AandBbands

摘要: Cloud height and cloud coverage detection are important for total ozone retrieval using ultraviolet visible scattered light. Use of the O2 A B bands, around 761 687 nm, by a satellite-borne instrument moderately high spectral resolution viewing in nadir makes it possible to detect top related parameters, including fractional coverage. The measured values spectrometer convolutions slit function atmospheric transmittance between satellite. Studies here determine optical depth satellite orbit Earth or accuracy FASCODE 3. parameter determined least squares fitting calculated radiance ratios oxygen bands. grid search method is used space minimize an appropriate sum deviations. For this search, nonlinearity (i.e., leverage based on varying amounts saturation absorption spectrum) distinguishing Using above-mentioned method, operational algorithm which uses minimal computation time can be implemented.
