MODIS L1B数据的辐射定标及太阳天顶角订正研究

Research of MODIS L1B-level Data Radiometric Correction and Solar Zenith Correction

针对MODIS L1B级数据存在的3个主要问题:图像几何校正、卫星参数定标、太阳天顶角校正,在总结前人研究的基础上提出解决方案,完成对MODIS L1B级数据辐射定标以及太阳天顶角订正,期望提供MODIS数据深层次应用的基础。

Proposals to tackle with the three main problems existing in pre-processing of MODIS L1B-level data,i.e.,image geometric correction,satellite parameters calibration,solar zenith angle rectification,were put forward on the basis of summarizing experience of the former relevant researches to complete the radiometric correction and solar zenith angle rectification,which might provide the MODIS data application with good theoretical foundation.
