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
