An Improved Method to Retrieve the Clear Column Radiance from Partially Cloudy Spots of Radiometer on Board Satellite

[摘要] Based on the work of Aoki (1980) an accurate and computationary fast method has been developed for the clear radiance retrieval in the case where the AVHRR picture data cannot be used because of, e.g., the limitation on the computation time. The present method has been applied to the observed radiance data by NOAA-6 meteorological satellite. It has been shown that the present method without the usage of the AVHRR data is slightly worse in accuracy than the method with using the AVHRR data but highly accurate than the current method of McMillin.A new type of the hardware system for the vertical sounding from satellite has been proposed, slightly modifying the current TIROS-N type sounding instruments.
