The Laboratoire des Sciences du Climat et de l’Environnement and the Cyprus Institute are looking for a motivated candidate for a fully funded PhD for three years. This PhD is part of the EU-funded Eastern Mediterranean and Middle East– Climate and Atmosphere REsearch EMME-CARE project (http://emme-care.cyi.ac.cy/) which aims at establishing a long-term knowledge hub around Cyprus for environmental and climate change research and sustainable solutions. The PhD candidate will be based at LSCE with visits to The Cyprus Institute. Detection and quantification of the emissions of greenhouse gases and pollutants using satellite data across the eastern Mediterranean and Middle East region Background The space-borne high resolution imagery of NO2, CO, SO2 and CH4 by the TROPOMI instrument on-board Sentinel-5P since 2018 opens new opportunities for the monitoring of the NOx, CO, SO2, CH4 and potentially CO2 anthropogenic emissions using atmospheric inversion approaches. The main concept for such a monitoring is to detect gas concentration plumes from large cities and power plants in the satellite images, and to infer the corresponding emission rate based on knowledge on the local wind field, e.g. from meteorological analyses. The large cities, industrial sites and plants whose instant to annual emissions could be retrieved within a few tens of percent to a few percent should represent a large part of the global anthropogenic emissions. The application of such a concept over the Eastern Mediterranean – Middle-East (EMME) area should bring key information about the emissions of pollutants and greenhouse gases of this area, where most countries lack precise inventories. Overall aim The proposed PhD thesis would be dedicated to the development and application of an inverse modelling system for a systematic detection and analysis of atmospheric plumes from point source and intense area sources in TROPOMI images, potentially helped by CO2 column retrievals from the OCO-2 satellite, over the EMME area in order to quantify and map the pollutant concentrations from cities, industrial facilities and power plants and their emissions. The results will be analysed in terms of trends, sectors of activity, and more generally in terms of the specific socio-economic drivers of the EMME area. The analysis of results will be supported by the expertise of the Cyprus Institute on emission inventories for regions and cities where partnerships are or will be established in collaboration with the atmospheric chemistry modelling group of the Cyprus Institute Requirements - Programming skills, preferably in Python and Fortran - Basic understanding of satellite images and spatial analyses - Knowledge on modelling, data science, atmospheric sciences Contacts At the LSCE: email@example.com, firstname.lastname@example.org and at the Cyprus Institute: email@example.com -- Frédéric CHEVALLIER Lab. des Sciences du Climat et de l'Environnement L'Orme des Merisiers, Bat 714, Point courrier 129 91191 Gif sur Yvette Cedex, France.
