CAMS2_53c Development and provision of observation-based hot-spot emissions of CH4, NO2, and CO2 from existing satellites and the first CO2M mission

Description du marché

ECMWF, as the Entrusted Entity for the Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for provision of Development and provision of observation-based hot-spot emissions of CH4, NO2, and CO2 from existing satellites and the first CO2M mission. These services are for extending the monitoring of large point sources and hotspot emissions in CAMS to also include nitrogen oxides (NOx) and carbon dioxide (CO2) and prepare for the uptake of CO2M observations for CH4. The aim of such a service is to evaluate and complement emission point source databases and provide monitoring of the emissions over time. To progress towards operational maturity in anticipation of the CO2M satellite mission, planned to be launched by the end of 2027, this ITT therefore focuses on the following main topics: • Implement a (pre-)operational service to detect and estimate NOx emission from local sources based on current operational satellites. • Further develop and evaluate the methodology to estimate NOx emissions from NO2 satellite observations. • Further develop and evaluate the use of NO2 emissions estimates to constrain the estimation of CO2 emission sources. • Further develop and evaluate the methodology to estimate CO2 emissions from local sources with existing satellite data in preparation for the CO2M satellite. • Further develop and evaluate the methodology to estimate CH4 emissions from local sources with existing satellite data in preparation for the CO2M satellite.
