Estimation of Drought Monitoring Ability of FY-3A MERSI Data

The FY-3A satellite is an obit meteorological satellite which can provide the globalizational,three-dimensional,multi-spectral remote sensing images.One of the FY-3A missions is monitoring the natural disaster and the change of environment all over the world.We analyze the ability of drought monitoring using the FY-3A MERSI data.First,the art of status of FY-3A satellite is introduced and the potential ability in drought monitoring is discussed.Second,the FY-3A MERSI and MODIS data are preprocessed and analysed.Finally,the relativel precision between the results of FY-3A MERSI and MODIS data are analyzed.The results of experiment indicate that the FY-3A MERSI data can improve the drought monitoring ability in same spatial and spectral resolution aspects.
