The GPP of Northern Hemisphere forests predicted by the FORCCHN2 model coupled with five phenology models

The gross primary productivity (GPP) dataset outputted by the five coupled models: Thermal-FORCCHN2, Sequential-FORCCHN2, Parallel-FORCCHN2, Unichill-FORCCHN2, and DORMPHOT-FORCCHN2 model. <br> The period is 1982–2018. <br> The region is the Northern Hemisphere forests above 30^o N (latitude 30^o to 90^o N, longitude -180^o to 180^o).
