“艾利”台风过程中FY-2C与TRMM卫星红外通道信号差异分析

为了了解不同卫星平台上类似仪器探测结果的差异,分析对比了2005年8月27日至9月3日“艾利”台风期间, 风云二号C星(FY-2C) 自旋扫描辐射器(VISSR)与热带测雨卫星(TRMM)可见光及红外扫描仪(VIRS)中红外和远红外探测结果差异。研究结果表明,70%以上的VISSR和VIRS红外辐射亮温差小于5 K;晴空状况下VIRS较VISSR红外通道平均亮温偏低幅度小于1.5 K;有云情况下远红外通道VIRS比VISSR相应通道亮温平均偏高幅度也小于1.5 K,但中红外通道VIRS与VISSR的亮温差异较大,且随着云顶的升高,差异也增大。

Abstract

In order to comprehend signal similarities and differences observed by similar instruments on board different satellite platform, the infrared channel signals observed between FY-2C VISSR and TRMM VIRS during process of typhoon “Aili” from Aug. 27, 2005 to Sep. 3, 2005 are compared. Statistical results indicate that more than 70% samples have less than 5 K infrared temperature differences observed between FY-2C VISSR and TRMM VIRS. In the condition of clear sky, results display less than 1.5 K in average brightness temperature observed by VIRS than by VISSR, which is the same for the cloudy sky at the far infrared channel of the both instruments. However, there are relative large differences of brightness temperature detected by both instruments at the middle infrared channel in the cloudy sky, and these differences increase with the rising of cloud tops.
