On Estimating Global Monthly Carbon Dioxide Fluxes by Region, utilizing the observational data obtained by the Greenhouse gases Observing SATellite "IBUKI" (GOSAT)

October 28, 2011

The Ministry of the Environment Japan, the National Institute for Environmental Studies, and the Japan Aerospace Exploration Agency jointly conduct the GOSAT Project. GOSAT itself was launched on January 23, 2009.
Using observational data from GOSAT and ground-based data, the estimation of monthly regional CO2 sources and sinks (net fluxes) and their uncertainty was carried out. It was demonstrated that the CO2 concentration data retrieved from GOSAT soundings can reduce the uncertainty of fluxes estimated from ground-based data alone.
The outcomes of this research were published in the Meteorological Society of Japan's Scientific Online Letters on the Atmosphere (SOLA) on October 29, 2011. These estimations will now be disseminated to affiliated researchers selected by means of GOSAT Research Announcements. Following the assessment and validation of these results by the researchers, the improved flux data will be made available to the general public.
