| 摘 要： | 该文利用探空资料, 用辐射传输模式LOWTRAN 7, 计算了卫星的入瞳辐射率, 确定了FY-2和GMS-5卫星多通道扫描辐射计水汽通道定标系数.由于星蚀期间星上温度变化迅速, 星蚀期间的外定标考虑了星上黑体定标, 并用实际观测值和探空资料做了检验。通过近半年的运行, 这种方法取得了较好的效果.

| Abstract: | By using the radiosonde data and Lowtran 7,the radiance is calculated,and the calibration coefficients of FY 2 and GMS 5 water vapor channels are fitted .During the period of around equinox eclipse ,the temperature on satellite would change rapidly ,and the vicarious calibration combining with in flight calibration would be considered.The validations are made using radiosonde data and GMS 5 observational values.The vicarious calibration has got a good result in the operations for half a year . |
