Model simulation results for "Enhanced seasonal amplitude of atmospheric CO2 by the changing Southern Ocean carbon sink"

This dataset contains the seasonal variations of monthly mean atmospheric CO2 concentration derived from GEOS-Chem model simulations during 2000-2016. Monthly terrestrial CO2 fluxes derived from CLM4.5-CN, used as an input dataset for the GEOS-Chem simulations, are also included. There are six sets of GEOS-Chem simulation results; "ctrl", "BIOfix", "OCNfix", and "FFfix" are the main experiments to evaluate the effects of changes in terrestrial CO2 fluxes, air-sea CO2 fluxes, and fossil fuel CO2 emissions on the seasonal amplitude of atmospheric CO2 over the globe; "ALLfix" and "OCNfix_SO" are additional experiments for identifying the effects of changes in the other factors (i.e., atmospheric transport and biomass burning) and regional changes in air-sea fluxes in the Southern Ocean. Detailed explanations for each simulation are described in the main text. *We recommend contacting us first if you want to utilize the dataset for study ([e-mail]).
