Improving gross primary production estimation accuracy on the Qinghai-Tibet Plateau considering the effect of atmospheric CO2 fertilization

This GPP dataset was generated by the improved GPP estimation model which introduced atmospheric CO₂ fertilization effect and canopy-to-leaf CO₂ concentration gradients into the CASA model. The dataset was provided in TIF format at a month interval. The valid value ranges from 0 to 1000, and the background filled value is set to NoData. The scale factor of the data is 1. Each TIF file represents a month GPP at a daily cumulative value (unit: g C m^-2 month^-1).
