摘 要: | 采用无植被的戈壁、沙漠为检验辐射定标的目标区。运用统计方法,将NOAA-9的AVHRR通道1和2反射率资料标准化到NOAA-10,使这两颗卫星的资料及其反演的参量能进行比较。用1986年10月—1988年9月共15个月的资料进行检验,得到满意的结果。

Comparison of AVHRR Channel 1 and 2 Albedo Data Between NOAA-9 and NOAA-10 and Its Calibration |

Abstract: | The channel 1 and 2 of AVHRR on NOAA polar orbit satellites have no on-board calibration capabilities. Therefore, a methodology is developed to make comparison analysis on the data measured by NOAA-9 and NOAA-10 by using the earth surface with neglectable seasonal changes as the target area. A statistical method to normalize NOAA-9 data to those of NOAA-10 is presented. |
