泾河流域MODIS MOD13A2 增强型植被指数（EVI）数据集（2000-2021年）

增强型植被指数(EVI)是在归一化植被指数(NDVI)改善出来的，根据大气校正所包含的影像因子、大气分子、气溶胶、薄云、水汽和臭氧等因素进行全面的大气校正。EVI大气校正分三步，第一步是去云处理。第二步是大气校正处理，校正内容除了NDVI已有的瑞利散射和臭氧外，还包括大气分子、气溶胶...

The Enhanced Vegetation Index (EVI) is developed based on the Normalized Difference Vegetation Index (NDVI), and comprehensive atmospheric correction is conducted by taking into account image factors, atmospheric molecules, aerosols, thin clouds, water vapor, ozone and other relevant factors involved in the atmospheric correction process. The atmospheric correction workflow for EVI consists of three steps: the first step is cloud removal, and the second step is atmospheric correction processing, which covers not only the Rayleigh scattering and ozone already included in NDVI correction, but also atmospheric molecules, aerosols...
