Novel algorithm for retrieving spatial scale of precipitating clouds from low-orbiting satellite observations
利用卫星轨道资料获取降水云团尺度的新方案

A new scheme was proposed in this study to account for such a handicap, which is based on the statistics of object area fraction that is somewhat insensitive to the orbit truncation. In order to get a measurement that could be accurately received, continuous circle object was consulted. Accordingly the equivalent radius was finally defined by using a minimum deviation principle to indicate the object scale. Since the equivalent radius is an indirect indicator of object spatial scale, it could be used as a secondary strategy to modify the results from counting method, by which the underestimate would be restrained to some extent.
