摘　　要：以敦煌辐射校正场地区为研究区,分别利用6S和FLAASH大气校正模型对Landsat8卫星OLI影像进行大气校正,将其校正结果与MODIS地表反射率产品MOD09GA进行比对,检验两种校正模型的精度.研究结果表明,除绿波段外,蓝、红和近红外波段的FLAASH校正精度均高于6S校正精度.In this paper,the Dunhuang radiation correction field is taken as the research area,and the OLI images of Landsat 8 satellite are corrected by 6S and FLAASH atmospheric correction models respectively.Then the corrected results are compared with MODIS surface reflectance production MOD09GA.The research results show that the accuracies of FLAASH correction in blue,red and near infrared bands are higher than that of 6S except in green band,which will provide a technical reference for users in atmospheric correction of Landsat 8 satellite OLI images.
