Near-surface-sensitive satellite observations of atmospheric greenhouse gases (CO2, CH4): Past, present and future — •Michael Buchwitz, Maximilian Reuter, Oliver Schneising, Jens Heymann, Heinrich Bovensmann, and John P.

Carbon dioxide (CO2) and methane (CH4) are Essential Climate Variables (ECVs) because they are important greenhouse gases contributing to global warming. Despite their importance our knowledge about their variable sources and sinks has significant gaps. Near-surface-sensitive global satellite observations of atmospheric CO2 and CH4 in combination with inverse modelling or other approaches helps to close important knowledge gaps. At the Institute of Environmental Physics (IUP) of the University of Bremen (UB) column-averaged dry-air mole fractions of CO2 and CH4, i.e., XCO2 and XCH4, are retrieved from the European satellite instrument SCIAMACHY on ENVISAT and from the Japanese instrument TANSO-FTS onboard GOSAT. Furthermore, IUP-UB is leading two European projects focusing on satellite retrievals of XCO2 and XCH4 and IUP-UB was and is also involved in the specification of future satellites. In this presentation an overview about these activities will be given.
