The European Space Agency (ESA), in collaboration with the European Commission (EC) and EUMETSAT, is developing a space-borne observing system for quantification of anthropogenic carbon dioxide (CO2) emissions. Forming part of the EC's Copernicus programme, the CO2 monitoring (CO2M) mission will be implemented as a constellation of identical satellites, measuring carbon dioxide and methane concentration in terms of column-averaged mole fraction (XCO2 and XCH4 ). Each satellite will continuously image XCO2 and XCH4 along the satellite track on the sun-illuminated part of the orbit with a swath width of >250 km. Observations will be provided at a spatial resolution of 2km x 2km, with high precision (<0.7 ppm) and accuracy (bias <0.5 ppm). To this end, the payload comprises a suite of instruments addressing the various aspects of the challenging observation requirements: A push-broom imaging spectrometer will perform co-located measurements of top-of-atmosphere radiances in the Near Infrared (NIR) and Short-Wave Infrared (SWIR) at high to moderate spectral resolution (NIR: 747-773nm@0.1nm, SWIR-1: 1595-1675nm@0.3nm, SWIR-2: 1990-2095nm@0.35nm). These observations are complemented by measurements in the visible spectral range (405-490 nm@0.6nm), providing vertical column measurements of nitrogen dioxide (NO2), which serves as a tracer to assist the detection of fossil-fuel emission plumes. A Multi-Angle Polarimeter (MAP) will perform co-located measurements of aerosol densitiy to ensure high-quality retrievals of carbon dioxide concentration even over polluted industrial regions. The instrument suite is completed by a three-band Cloud Imager providing cloud-flagging capacity at sub-sample level (<200m resolution). The poster presents the preliminary design of the CO2M instruments, as well as results from pre-development activities for critical technologies.
