The Copernicus Carbon Dioxide Monitoring (CO2M) mission will measure atmospheric anthropogenic carbon dioxide and nitrogen dioxide and forms part of the European Commission’s Copernicus Earth observation programme and is developed by the European Space Agency (ESA), in collaboration with EUMETSAT. To compensate for the significant error in CO2 measurements which could be caused by aerosols in the Payloads field of view, the Multi Angled Polarimeter (MAP) instrument has been included on the payload. The CO2M Mission consortium is led by OHB with Thales Alenia Space in France as Payload Prime. The MAP instrument is designed, assembled and characterized by Thales Alenia Space in the UK. MAP is a multi-angle (>40 angles) and multi-spectral (7 bands, 400-900nm) polarimeter. It utilizes a focal plane assembly that has a micropolarizer and spectral filter mounted directly on the detector to perform both polarization and spectral separation. To achieve the demanding swath (300 km), zenith angle (+60°/-60°) and straylight requirements in a compact volume, a novel arrangement of 4 telescopes with wide fields of view has been developed. This paper will summarize the current status of the MAP instrument. This includes the design, performance and test status at instrument CDR.
