The European Union supports the development of an operational service for such a monitoring in the frame of Copernicus, its Earth observation programme. The service will exploit atmospheric and Earth observation data from various observation systems, in particular satellite images and near surface measurements of atmospheric CO2 and co-emitted tracers. It will rely on atmospheric modeling together with data assimilation and atmospheric inversion techniques. <br class=""><font color="#5856d6" class=""><br class=""></font>The series of European projects H2020 CHE, H2020 CoCO2 and now Horizon CORSO aims to provide the prototype system for this service. LSCE has been a key partner of these projects, coordinated by ECMWF, and has participated in various activity segments. In particular, in CORSO, the LSCE team will participate to the assessment of the added value of 14CO2 (radiocarbon) measurements for the monitoring of the fossil fuel emissions (relying on the fact that fossil fuels are radiocarbon free). It will develop a dedicated atmospheric transport modeling and inversion configuration which can assimilate 14CO2 data together with CO2 data and apply it for a 20-year analysis of the emissions at global to European scale.<br class=""><font color="#5856d6" class=""><br class=""></font><b class="">Job description - Responsibilities:</b><br class=""><font color="#5856d6" class=""><br class=""></font>- Conduct and analyze 14CO2 atmospheric transport simulations at global to regional scales using the LMDZ and CHIMERE transport models and 14CO2 flux products from the CORSO project<br class="">- Implement modules for the assimilation of 14CO2 measurements in the Community Inversion Framework (CIF, <a href="http://community-inversion.eu/" class=""><font class="" color="#0433ff">http://community-inversion.eu/</font></a>), which is coupled to the LMDZ and CHIMERE models; contribute to the improvement of the interface between LMDZ and the CIF <br class="">- Conduct and analyze atmospheric inversions to quantify the fossil fuel emissions of the last 20 years in the Northern Hemisphere using a global 14CO2 measurement database, and in Europe during a year of intensive sampling of 14CO2<br class="">- Interact regularly with LSCE researchers connected to these activities and with the European partners of CORSO to ensure that the developments rely on state-of-the-art approaches and for the analysis of the inversion results<br class="">- Lead and contribute to the writing of subsequent peer-reviewed publications<br class="">- Promote the results at international conferences<br class=""><font color="#5856d6" class=""><br class=""></font><b class="">Required skills/experience:</b><br class=""><span class="Apple-tab-span" style="white-space: pre;"> </span><br class="">- Knowledge in atmospheric sciences and/or statistical inversion (data assimilation) techniques <br class="">- Experience with atmospheric transport, meteorological models and/or data assimilation systems<br class="">- Programming (ideally in Python)<br class="">- Ability to work collaboratively with a team of researchers<br class=""><font color="#5856d6" class=""><br class=""></font><b class="">Education:</b> PhD in climate, environmental or atmospheric sciences, or in applied mathematics. <br class=""><font color="#5856d6" class=""><br class=""></font><b class="">What the LSCE and CORSO can offer you:</b><br class=""><font color="#5856d6" class=""><br class=""></font>The LSCE is a world-class research laboratory established as a collaboration between the Commissariat à l'Énergie Atomique et aux Énergies Alternatives (CEA), the Centre National de la Recherche Scientifique (CNRS) and the University of Versailles Saint-Quentin (UVSQ).
