The CO2 Monitoring (CO2M) mission is the space component of the European integrated monitoring and verification support capacity (MVS) dedicated to the monitoring of anthropogenic CO2 emissions. This CO2-MVS is part of the next Copernicus program component by the European Commission and will be implemented jointly by ESA, EUMETSAT and ECMWF. This European anthropogenic CO2 MVS has the following objectives:

  1. The operational provision of atmospheric CO2 measurements obtained from dedicated space-borne sensors, complemented by in-situ networks and ancillary observations.
  2. The operational provision of top-down anthropogenic CO2 emission maps and anthropogenic emission maps, with high spatial and temporal resolution, and short time updates.
  3. The operation of a data-assimilation system, which will integrate atmospheric measurements with bottom-up information into consistent and accurate estimates of anthropogenic CO2 emissions and their trends.
  4. The provision of a decision support tool.

EUMETSAT is developing a significant part of the CO2M ground segment to undertake the day-to-day operations of CO2M and the processing of CO2M products, as part of the Copernicus Third Party Program. ESA is developing the space-segment and parts of the overall CO2M ground segment. The CO2M Payload Data Processing Segment (PDPS) and its operational products provided by EUMETSAT and its partners, will contribute to the first objective of the integrated observation system.


CO2M products
