Emergent constraints on historical and future global gross primary productivity

This is the supporting data of the paper "Emergent constraints on historical and future global gross primary productivity", which includes three documents:
GPP_RS: Gross primary productivity (GPP) estimates (PgC yr-1) for global, different vegetation types and different latitudinal zones in 2001-2014 in remote sensing-based GPP dataset and site-scale average GPP (gC m-2 yr-1).
GPP_CMIP6: Historical GPP estimates (PgC yr-1) in 2001-2014 and future GPP estimates (PgC yr-1) for different scenarios in 2081-2100 in Coupled Model Comparison Project 6 (CMIP6) datasets.
GPP_TRENDY: Global GPP estimates (PgC yr-1) in "Trends and drivers of the regional scale terrestrial sources and sinks of carbon dioxide" (TRENDY) dataset in 2001-2014 and site-scale average GPP (gC m-2 yr-1).
