The position is proposed in the frame of the PyroStrat project funded by the ANR (French research council) from January 2022 to December 2025. The general objective of this project is to quantify the impact of the emissions from megafires reaching the stratosphere (i.e. pyrocumulonimbus) on the composition and radiative balance of the stratosphere from seasonal to interannual timescales. PyroStrat research studies rely on the analysis of various types of observations and models outputs. In this project, the contribution of the CNRM laboratory is to study the effect of pyrocumulonimbus on stratospheric ozone depletion. For this purpose, we will use the MOCAGE-CTM global chemistry-transport model developed at CNRM to study the composition of the troposphere and the stratosphere. MOCAGE-CTM numerical experiments will be run to simulate case studies of megafires and also a much longer period covering the last decade when most of the megafires took place. The research work at CNRM will be done in collaboration with the partners of the project, in particular LATMOS in Paris (for the fire emission estimates and in link with climate studies) and LOA in Lille (in link with radiative budget studies).
The successful candidate will be in charge of the studies based on MOCAGE-CTM
model consisting of:
• setting up, running and evaluating MOCAGE-CTM simulations
• analysing and communicating the results (presentations, publications).
• Strong numerical (Linux, Fortran, Python) skills are required.
• Some experience with atmospheric numerical modelling and/or with complex codes on high performance computers (HPC) would be a clear asset.
• At least a CEFR B2 level in English language (speaking, understanding and writting) or an equivalent level is required.
The work will be carried out in the Centre National de Recherches Météorologiques (CNRM, Toulouse, France).
The CNRM (http://www.umr-cnrm.fr/spip.php?rubrique1&lang=en) is responsible for conducting the largest part of the Météo-France research activities in weather forecasting, climate modelling, atmospheric chemistry, oceanography and land-surface processes. Within CNRM, the climate research group hosting the COMETS team is in charge of understanding scale interactions, interactions between the various components of the climate system including air composition, the response of the climate system to anthropogenic forcing, and sources of variability and long-term predictability. These activities are carried out in particular through the modelling of climate, atmospheric composition and air quality at global and regional scales, participation in model intercomparison exercises such as CMIP and their analysis, impact studies and the detection-attribution of observed climate change.
The successful candidate will join the COMETS team (http://http://www.umr-cnrm.fr/spip.php?article371&lang=en) which is the Météo-France research team in charge of the study of the chemical composition (reactive gases, aerosols and green-house gases) of the troposphere and of the stratosphere from the global scale to the regional scale. This team is composed of 8-9 people working on the tracer transport, the chemical processes, the air composition tendency from multi-annual to multi-decadal time range, and the impact of climate change on air composition.
