| 摘 要： | 基于卫星资料观测和反演降水是当前监测全球尺度降水的主要方式,而其中一大难题就是如何将降水云与非降水云在像素尺度进行有效分离,这也是准确反演地表降水量的基本前提.为建立一套适用于常见星载可见光/红外探测仪器的降水云识别方法,本文利用热带测雨卫星( TRMM)可见光/红外辐射计(VIRS)和测雨雷达(PR)的融合观测资料,...

| Abstract: | Satellite remote sensing is currently the most important way of global-scale precipitation observations.The identification of precipitating clouds based on the satellite-borne measurements is still one of the most challengable problems.In order to get a universal precipitating-cloud identification method available for common optical satellite measurements,the relationship between cloud parameters and precipitating-cloud pixels is analyzed by using matched TRMM Visible and Infrared Scanner(VIRS) and Precipit... |
