The hydrometeor information from the cloud model is then used as input into a 3 - d microwave radiation transfer model that calculates the upwelling radiance received by the rediometer aboard the satellite 将云模式模拟的水汽凝结体信息作为三维微波辐射传输模式的输入值，计算星载微波辐射计接受到的上行辐射。

A comparison between microphysical characteristics derived from 3 - d cloud model and the results from trmm tmi and pr products show that the selected cloud model gives a relatively realistic hydrometeor profiles 由三维云模式得到的微物理特征与由微波图像仪tmi和pr产品提供的结果之间的对比表明，所选用的云模式能够给出相对真实的水汽凝结体廓线。

The resulting brightness temperature ( tb ) , hydrometeor structure , and surface rainfall rate relations show that the ice hydrometeor , espatially the ice at the top of the precipitating cloud , decreases the brightness temperature significantly at 85 结果表明，在85 . 5ghz ，冰相水汽凝结体尤其是处于降水云顶部的冰晶粒子由于散射辐射而使得亮温显著降低。亮温与冰相粒子的含量之间有很强的相关性。

The brightness temperature is highly related to the density of ice hydrometeor . since the convective cloud system is tilted , and the viewing angle is oblique , the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between tb and surface rainfall rate is relatively small 但亮温和地面降水强度之间的相关性较弱，这是由于该对流系统为倾斜的，冰相粒子和地面降水强度之间存在着位置上的不一致，并且观测角为倾斜的。
