利用印度遥感卫星IRS3（印度遥感卫星3号）上的MOS（模块化光电扫描仪）测量的后向散射太阳辐射进行了云顶压反演。该算法使用了761 nm的氧- a吸收带吸收通道和750 nm的窗口通道之间的辐射比。这些比值与平均光子路径长度直接相关，而平均光子路径长度主要由云顶压决定。本文介绍了检索方案的原理，灵敏度研究的结果和使用无线电探空仪的首次验证。
Backscattered solar radiation as measured by MOS (Modular Optoelectronical Scanner) on the IRS3 (Indian Remote sensing Satellite 3) has been used in an algorithm to retrieve cloud top pressure. The algorithm uses a radiance ratio between absorbing channels in the Oxygen‐A absorption band at 761 nm and a window channel at 750 nm. The ratios are directly related to the average photon path length, which is mainly determined by the cloud top pressure. This paper presents the principles of the retrieval scheme, results of a sensitivity study and a first validation using radiosondes.
