Global dryland vegetation memory

NDVI data was downloaded from https://climatedataguide.ucar.edu/climate-data/ndvi-normalized-difference-vegetation-index-3rd-generation-nasagfsc-gimms using the gimms R package (https://cran.r-project.org/web/packages/gimms/index.html). The data was subsequently aggregated to monthly maximum raster layers and masked to dryland regions. ERA5 data was downloaded from the Climate Data Store and downscaled using R.

归一化植被指数（Normalized Difference Vegetation Index）数据通过gimms R包（https://cran.r-project.org/web/packages/gimms/index.html）从https://climatedataguide.ucar.edu/climate-data/ndvi-normalized-difference-vegetation-index-3rd-generation-nasagfsc-gimms 下载获取。随后将该数据聚合为月度最大值栅格图层，并掩膜至干旱区范围。ERA5数据从气候数据存储中心下载，并通过R语言完成降尺度处理。
