| 摘 要： | 应用热带降雨测量卫星微波成像仪(TRMM/TMI)的被动遥感资料,选用对云中液态水变化非常敏感的85.5 GHz垂直极化通道的亮温信息,通过离散纵坐标矢量辐射传输模式,采取逐步逼近的方法确定出地表的微波比辐射率,并运用迭代方法有效地反演出云中液态水含量及其分布.与对应的卫星红外云图对比结果表明,反演的云中液态水分布是合理和可信的.

| Abstract: | Passive remote sensing data from the TRMM Microwave Imager (TMI) have been applied. The brightness temperature of the TMI 85.5 GHz channel in the vertical polarization, which is greatly sensitive to the cloud liquid water (CLW), was used for the CLW retrieval. Based on the Vector DIScrete Ordinate Radiative Transfer (VDISORT) model, the microwave emissivity of the Earth's surface was determined using a numerical step by step method. By means of the iteration method, the amount of CLW and its distribution were successively retrieved. Compared with the corresponding satellite infrared cloud chart, the retrieved distribution of CLW is reasonable and believable. |
