A feasible method on atmospheric correction to channel 1 and 2 for MODIS(MODIS通道1和通道2大气订正的一种快速实用方法)
提出了利用气象资料对MODIS影像进行大气校正的一种快速实用方法.读取MODIS前两个通道250 min的反射率,采用常用的黑色目标扣除法(Dark-object subtraction)计算天空程辐射,通过卫星过境时刻的气象能见度和水汽资料计算大气造过率,表后推导出目标物的反射率. 通过比较两个邻近日期MODIS影像校正前后的归一化植被指数(NDVI)值,得出利用本文提出的方法对MODIS进行大气校正所得到的NDVI值更接近实际情况.
