Monthly EVI Data of the Southern Slope of the Qilian Mountains from 2003 to 2022

The MOD13Q1-EVI data used has a spatial resolution of 250 meters and a temporal resolution of 16 days, covering the time scale from January 1, 2003, to December 31, 2022. The global MOD13Q1 images of EVI data from 2003 to 2022 were acquired online through the Google Earth Engine (GEE) platform using JavaScript API. Monthly EVI data were synthesized using the maximum value composite method, and images for each month within the study area were clipped based on vector boundary maps to form the EVI dataset for the years 2003-2022.
