Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic greenhouse gases (GHGs). Satellite observations combined with modelling can add important missing global information on regional CO2 and CH4 sources and sinks required for better climate prediction. GHG-CCI aims at delivering the high quality satellite retrievals needed for this application.
