Calibrated WRF-VPRM Model Projections of Monthly Terrestrial Carbon Fluxes (GEE, RES, NEP) for China (2020–2060) under SSP126, SSP245, and SSP585 Scenarios

This dataset presents projected monthly gridded terrestrial carbon fluxes (GEE, RES, and NEP) for China from 2020 to 2060 under climate-driven temperature changes, derived from the calibrated WRF-VPRM model. The model was calibrated against multi-site eddy covariance observations to reduce systematic biases in gross ecosystem exchange (GEE) and ecosystem respiration (ER) simulations. The dataset includes three NetCDF files corresponding to three Shared Socioeconomic Pathway scenarios: ssp126_China_GEE_RES_NEP.nc, ssp245_China_GEE_RES_NEP.nc, and ssp585_China_GEE_RES_NEP.nc. Each file contains: 1D metadata: geographic grid coordinates (latitude/longitude) and time indices covering 2020–2060 at 5-year intervals (9 time slices). 3D variables (time × latitude × longitude) at the native WRF-VPRM resolution, with monthly mean values: GEE: gross ecosystem exchange (carbon uptake is negative), units: gC m⁻² mon⁻¹ RES: ecosystem respiration (carbon release is positive), units: gC m⁻² mon⁻¹ NEP: net ecosystem productivity (calculated as NEP = −(GEE + RES)), units: gC m⁻² mon⁻¹ Missing or invalid values are flagged using a fill value of -9999.0.
