The society is facing a major environmental challenge: developing coordinated monitoring and mitigation strategies leading to optimal reduction of both air quality and climate change impacts. In this context, the French-funded ARGONAUT project (PollutAnts and gReenhouse Gases emissiOns moNitoring from spAce at high ResolUTion) aims at providing new estimates of French anthropogenic emissions of the main gaseous pollutants (nitrogen oxides - NO<span class="gmail-" style="top: 1pt;">x</span>, carbon monoxide - CO and non-methane volatile organic compounds - NMVOCs) and carbon dioxide (CO<sub class="gmail-">2</sub>) at high resolution. The approach chosen to tackle this issue is the atmospheric inversion of sources and sinks using data assimilation. Based on the past developments of a range of atmospheric inversion systems covering the global to the local scales, the French Laboratoire des Sciences du Climat et de l'Environnement (LSCE) and its partners of the ARGONAUT project will implement a sophisticated inverse modeling system, able to benefit from the high-resolution imaging of the last generation of satellites within the European Copernicus program (Sentinel-5P/TROPOMI and CO2M) to monitor the emissions at the national level.</span><span lang="EN-US" class="gmail-" style="font-size: 11pt;"><span class="gmail-"></span></span></p><p class="MsoNormal" style="margin-bottom: 6pt; text-align: justify;"><span lang="EN-US" class="gmail-" style="font-size: 11pt;">In this context, the LSCE is looking for a motivated PhD student to exploit the multiple-species high resolution imaging for CO, NO<sub class="gmail-">x</sub>, and CO<sub class="gmail-">2</sub>. The main objective is to analyze the local correlations between the various species and co-assimilate them in order to better constrain their emission estimates. Making a step forward in the joint assimilation of various species and addressing the correlation between them will improve the emission inventories and their consistency across species. More generally, it should help addressing air quality and climate change related emissions at the national to subnational scales.</span><span lang="EN-US" class="gmail-" style="font-size: 11pt;"><span class="gmail-"></span></span></p><p class="MsoNormal" style="margin-bottom: 6pt;
