MOD17A2H version 6 Gross Primary Productivity (GPP) global mosaics at 500 m resolution and difference in GPP for the period 2000-2017. Changes in GPP could be used to estimate land degradation or similar. Derived using the data.table package and quantile function in R. For more info about the MODIS LST product see: https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod17a2h_v006. Antartica is not included. All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention: veg = theme: vegetation, gpp = variable: gross primary productivity in kg C m2, mod17a2h.oct = determination method: MOD17A2H product, GPP values for October, d = median value / difference = difference between periods / u.975 = aggregation/statistics method: 97.5% probability upper quantile, 500m = spatial resolution / block support: 500 m, s0..0cm = vertical reference: land surface, 2000..2017 = time reference: from 2000 to 2017, v1.0 = version number: 1.0,
