珠江三角洲地区 FY-3卫星 MERSI 影像的大气校正方法研究
Study on atmospheric correction methods for FY-3 MERSI image over Pearl River Delta region
摘要
Abstract
Observed data from 86 weather stations in Guangdong province were used to provide parameters of a simplify method for atmospheric correction(SMAC)algorithm,and then the SMAC algorithm was employed to conduct atmospheric correction for 250 m resolution data from medium resolution spectral imager(MERSI).In or-der to validate effects of SMAC algorithm for MERSI data,the reflectance histogram of each band and the normal-ized difference vegetation index(NDVI)before and after atmospheric correction were compared,and the reflectivi-ty distribution characteristics in each meteorological station were analyzed.The results show that the reflectance in-terval of each band becomes wider and the reflectivity in the meteorological station is closer to the observation after atmospheric correction.Also,the histograms of NDVI are smoother and the peaks are higher after atmospheric cor-rection;the histograms of NDVI are more similar for the data with time closer.All these results suggest that this at-mospheric correction method is reasonable.关键词
