辐射偏差改正是在数据同化系统中正确利用卫星观测的一个重要和必要的步骤。格点统计内插(GSI)资料同化系统中使用的原始辐射偏差改正方案由两个部分组成：一个与空气质量有关的变分部分和一个扫描角部分。空气质量分量在GSI内更新，而扫描角分量在GSI外更新。
Radiance bias correction is an important and necessary step in the proper use of satellite observations in a data assimilation system. The original radiance bias‐correction scheme used in the Gridpoint Statistical Interpolation (GSI) data assimilation system consists of two components: a variational air‐mass dependent component and a scan‐angle component. The air‐mass component is updated within the GSI, while the scan‐angle component is updated outside the GSI.
