EUROCOM

Eurocom is a French-Swedish project (2015-2018) funded by the Swedish Research Council (VR). It is co-lead by the University of Lund (ULUND) and the Laboratoire des Sciences du Climat et de l'Environnement (LSCE).

Eurocom aims at quantifying CO₂ ecosystem fluxes in Europe with their space and time variations over the last decades, and at quantifying the contribution of the different drivers (climate, management) and processes (biophysical and biogeochemical).

Eurocom will achieve this through initiating a regional-scale inverse modelling intercomparison project. One of the project's activities is to harmonize regional CO₂ inversions over Europe with respect to time periods or general set-up components (e.g. use of ICOS data). This allows a direct comparison and synthesis of the estimated fluxes together with an estimate of associated uncertainties.

Team:

• ULUND: Marko Scholze (co-lead), Guillaume Monteil and Andrew McRobert
• LSCE: Grégoire Broquet (co-lead), Matthew Lang and Philippe Peylin
• ICOS-CP: Ute Karstens and Alex Vermeulen
