Simulation of the atmospheric CO2 measurements at Fuling with the inversion model results

CO2 is the greenhouse gas that influenced by human activities most and has a great impact on the climate change. Monitoring of global CO2 variations on a basis of, high precision has great significance for the study of global climate change and carbon cycle, as well as the understanding of CO2 sources and sinks. This study develops the forward model and inversion software system GF_VRTM-V1.0 for space-borne near-infrared hyperspectral measurements of CO2 into a ground-based observation version. The simulation results are compared with the ground-based data of the column-averaged mole fraction of carbon dioxide measured at Fuling, and showed general agreement.
