| 摘 要： | 利用1998年淮河流域能量和水循环试验(HUBEX)中的一次地面雷达与星载雷达(简称为双基雷达)联合探测雨强的资料,比较了现有的几种测雨雷达回波衰减订正方法.选取了一条比较有代表性的降水廓线,利用地基雷达数据对其进行衰减订正.结果表明,在雨区的中上部,星载雷达探测效果优于地基雷达;从"零度层亮带”往下至近地面,地基雷达探测效果优于星载雷达.

| Abstract: | The author suggests a new method, that is, the combination of two radar working on different platforms. What the author used as the case is some data selected from the HUBEX in 1998 and the TRMM PR data. Selecting a typical rain profile and correcting it by the ground-based radar data, the author concludes that the TRMM PR data are better than the ground-based radar data in the upper part of the rain area and are less satisfying than the later from the so called " zero-temperature level" to the surface. |
