Description

This contract 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 now satellite remote-sensing observations allow these to be monitored. The data provided so far by the pilot projects leading to CAMS have delivered time-series of CH4, CO2 and N2O surface flux fields of high-quality. This contract is for extending the time-series, both forwards and backwards (as far as possible) in time, while maintaining their quality at the highest international standard. Periodically, the contractor will reprocess the whole period in order to reflect improvements in spatial resolution as well as in modelling and data assimilation techniques used for the atmospheric flux inversions. The documentation of associated errors and comparison with independent observations as well as with main competing international products also forms part of the activities.
