Improved estimate of global gross primary production for reproducing its long-term variation, 1982-2017

This dataset provides 8-day global gross primary production (GPP) at 0.05° latitude by 0.05° longitude for 1982-2017. (1) Model description and performance The GPP dataset was generated by the revised EC-LUE model by integrating the regulations of several major environmental variables: atmospheric CO2 concentration, radiation components (i.e., direct and diffuse radiations), and atmospheric vapor pressure deficit (VPD). The revised EC-LUE performed well in simulating the spatial, seasonal, and interannual variations in global GPP. Particularly, it has a unique superiority in reproducing the interannual variations in GPP at both site level and global scales. (2) Dataset information Each .zip file contains all the 8-day GPP of a year at daily value. To obtain the summation of each 8-day (or 5-day or 6-day) period, please multiply the GPP value by corresponding days (8 for the first 45 values, and 5 or 6 for the last value). Data format: HDF Spatial extent: 90S-90N 180W-180E Fill value: 65535 Scale factor: 0.01 Unit: g C m^-2 day^-1 Any questions about the GPP dataset can be corresponded to [e-mail] (Wenping Yuan).
