The land use datasets (Liu et al., 2005) in 2000 and 2005 were derived from the Landsat TM/ETM data at a spatial resolution of 30 m and are available from the Data Sharing Infrastructure of Earth System Science (http://www.geodata.cn).
A monthly 1 km resolution NDVI (Normalized Differential Vegetation Index) MOD13A product between 2000 and 2010 was obtained from the NASA EOS DATA Gateway (https://wist.echo.nasa.gov/api).
