Data Set

Gross primary production, ecosystem respiration, net ecosystem CO2 exchange, wetland CH4 emission, cropland N2O emission
Time resolution
1 month
Spatial resolution
0.5 x 0.5 degree
Calculation method
The global model simulations were conducted with a spatial resolution of 0.5 x 0.5 degree in latitude and longitude, at a monthly time step. Net ecosystem CO2 exchange was calculated as the difference between photosynthetic uptake and respiratory emission, each of which is estimated with ecophysiological relationships. Methane emission from wetlands was calculate with two wetland schemes, which differ in complexity of methane-related processes. Nitrous oxide emission was calculated with a semi-empirical nitrification and denitrification scheme, including the effect of fertilizer input in croplands.
