风云一号卫星红外通道定标精度的检验

A TEST OF THE ACCURACY OF CALIBRATION FOR INFRARED CHANNELS OF THE FY-1 SATELLITE

在气象卫星资料的定量应用中,定标是极为重要的。文章应用相对定标方法,对FY-1B 和NOAA 卫星的红外通道的定标精度进行了相对检验,结果表明两者之间的偏差不超过±1℃。

Calibration is very important in application of meteorological satellite data.This paper uses a method of relative calibration to check the calibration accuracy of infrared channels for both FY-1B and NOAA-10 satellites,the results verified that their differences not exceed by±1℃.
