Missions

Marine aerosols play an important role in climate, and understanding their origin as well as their role in cloud formation and evolution is crucial. In the southern hemisphere, these aerosols have a major impact, although poorly understood. As part of the Sea2Cloud project and in collaboration with the french space research center (CNES), we offer a post-doc position to implement recent parameterizations of marine aerosols, cloud condensation and ice nuclei emissions in the WRF-Chem model. The aerosol fields obtained will be used to initialize a model using a detailed representation of cloud microphysics (DESCAM module developed at LaMP) in order to understand their impacts on cloud properties. These different modeling outputs, associated with the McRALI observable simulator (also developed at LaMP), will enable to compare the results obtained from aerosol and cloud fields simulated with LIDAR and RADAR type remote sensing measurements during the Sea2Cloud oceanographic campaign (March 2020) which took place aboard the R/V Tangaroa East of New Zealand.

Activities

-WRF-Chem simulations on an already defined area near New Zealand
- DESCAM simulation using the aerosol fields obtained with WRF-Chem
-Simulation of observables from lidar and radar systems (on board ships and satellites) with McRALI on aerosol and cloud fields simulated by WRF-Chem and DESCAM, respectively
-comparison of simulations / measurements from the ship campaign.

Skills

- knowledge of atmospheric modeling, if possible experience with WRF-Chem
- knowledge of atmospheric optics.
-experience in writing scientific articles
- English speaking and writing is a prerequisite

Work Context

Position is located in Clermont-Ferrand, at the Laboratoire de Météorologie Physique (LaMP)
