This dataset contains two raster data in IMG format:① EVI_annual_2000.img; ② EVI_annual_2010.img; This data represents the average vegetation index for Central Asia from April to September in 2000 and 2010, reflecting the state of vegetation cover on the surface, and EVI reducing the impact of background and atmospheric noise relative to the NDVI (Normalized Vegetation Index). The data were obtained by using MOD13A2 data, through stitching, clipping, projection transformation and other processes, and obtained the vegetation index of Central Asia every 16 days from April 1 to September 31, 2010, respectively, and then calculated the average vegetation index.
Using the corresponding MODIS data, through processes such as concatenation and clipping, the vegetation index for the specified date is obtained, and then the average vegetation index for the corresponding year is calculated
The obtained data needs to be organized and calculated before it can be used. The meteorological observation data and MODIS data within the research area should be organized and calculated, including blank data, missing measurement data, quality defects, etc. The problematic data should be analyzed and processed according to the situation to obtain high-precision data
