Greenhouse gases



JAXA has been observing the concentrations and distribution of greenhouse gases (carbon dioxide (CO2) and methane (CH4)), one of the causes of global warming in collaboration with the Ministry of the Environment (MOE) and the National Institute for Environmental Studies (NIES). In December 2015, the monthly average concentration of CO2 in the whole global atmosphere exceeded 400 ppm for the first time. It is clear that CO2 concentration in global atmosphere is increasing year by year.

By capturing the distribution and temporal changes of greenhouse gases in the globe, we can improve the estimation accuracy of greenhouse gas emissions and estimate the emission sources, which is utilized for international efforts to prevent global warming.
