The Biogeochemical Cycle Modeling and Analysis Section mainly conducts simulations and data analysis using numerical models to elucidate the global dynamics of greenhouse gases. It is one of the leading laboratories in Japan that widely covers the atmosphere, land, and water in model research. We also develop and apply various models used in the GOSAT project.
