Atmospheric monitoring of the CH4 emissions at the European scale

par Barbara Szenasi

Projet de thèse en Météorologie, océanographie, physique de l'environnement

Sous la direction de Philippe Bousquet et de Grégoire Broquet.

Thèses en préparation à Paris Saclay , dans le cadre de École doctorale des sciences de l'environnement d'Île-de-France (Paris) , en partenariat avec LSCE - Laboratoire des Sciences du Climat et de l'Environnement (laboratoire) , SATINV (equipe de recherche) et de Université de Versailles-Saint-Quentin-en-Yvelines (établissement de préparation de la thèse) depuis le 30-09-2017 .


  • Résumé

    This phd is organized with the ITN project Marie Curie MEMO2. The PhD will use the large amount of local estimates of CH4 emissions near sources from WP1 (including analysis of their isotopic signatures) to better constrain the emissions factors for the major natural and anthropogenic CH4 source sectors in Europe. Via the close link to the ESR8 project of UU-TNO, we will adjust the existing inventories from the INGOS and TNO-CAMS projects based on the new local scale results. The results from these local scale studies will be validated at the larger scale in this project. CH4 and 13CH4 concentrations will be simulated using regional atmospheric transport models driven by the original and the modified emission inventories. Comparisons between these simulated concentrations and the continuous CH4 and 13CH4 measurements of the European ICOS/InGOS network should provide a robust assessment of the different versions of the inventories, and thus of the improvement realized by the studies in WP1. ESR13 will focus on this analysis and on a further improvement of the estimate of European CH4 emissions using atmospheric regional inversions.
