Long-term (1982-2018) global gross primary production dataset based on NIRv

This dataset provides global monthly gross primary production (GPP) based on satellite NIRv (near-infrared reflectance) during 1982-2018 with a spatial resolution of 0.05 degree. Data format: netcdf. (Every .zip file contains all monthly GPP of a year) Spatial extent: 90S-90N 180W-180E Fill value: -9999 Scale factor: 0.001 Unit: gC m^-2 d^-1 Any questions about the GPP dataset can be corresponded to [e-mail] (Songhan Wang).
