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]).
