CAMS2_55_ter Provision of global inversion-optimised greenhouse gas fluxes and concentrations

This ITT, entitled “Provision of global inversion-optimised greenhouse gas fluxes and concentrations”, is for providing quantitative estimates of net surface fluxes of greenhouse gases, which are key drivers of the Earth's climate evolution. Ground-based and satellite remote-sensing observations allow these fluxes to be monitored. The data provided so far by CAMS have delivered time-series of CH4, CO2 and N2O surface flux fields of high quality. The successful Tenderer shall extend the time-series, both forwards and backwards (as far as possible) in time, while maintaining their quality at the highest international standard. The documentation of associated errors and comparison with independent observations as well as with similar products that are produced outside of CAMS will also form part of the activities. Finally, specific developments shall be included to further improve the data products. assessment of mitigation efforts.
