Proposal for a post-doctoral research position in ATMOSPHERIC CHEMISTRY MODELLING Laboratory: CNRM/GAME (Centre National de Recherches Météorologiques/Groupe d’études de l’Atmosphère Météorologique), Météo-France, Toulouse, France (www.cnrm.meteo.fr) The present post-doctoral position is proposed in the frame of the SHIVA project (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere, http://shiva.iup.uni- heidelberg.de/). SHIVA is funded by the European Community under the FP7 framework that started in July 2009. The central aim of SHIVA is to study the halogen very-short lived substances (VSLS) from their emission in the low troposphere up to the stratosphere, in relation with climate change. The sources of halogen VSLSs, which are mainly oceanic, are not yet well quantified and their impact of stratospheric ozone is still unknown, although possibly significant. In the frame of the project, a field campaign with coordinated ship and aircraft measurements will take place in November 2011 in Malaysia. Modelling work of the transport and chemistry of the VSLSs in the atmosphere will be done to complement the campaign measurements. The objective of the work done at CNRM/GAME in SHIVA is to study the transport, in particular in deep convection environment, and the chemical evolution of the VSLSs from their oceanic source up to the upper troposphere and the lower stratosphere at the local and regional scales. For this purpose, the Chemistry-CATT-BRAMS model will be used. This is a limited-area 3D meteorological model coupled with chemistry. The candidate will mainly work on the study of case studies from the SHIVA field campaign. The work will involve the use of the Chemistry- CATT-BRAMS model and of relevant observations from the field campaign. Preparatory work on the model will also be done by the candidate to prepare the SHIVA field campaign analysis. The position can start between February and June 2011. The net salary proposed is in the range 1800€ to 2500€ per month, depending on candidate’s experience. The work will be carried out at the Centre National de Recherches Météorologiques in Toulouse (France). The candidate must hold a PhD in atmospheric sciences and have preferably some experience in numerical modelling and/or atmospheric chemistry. Applications will be received by e-mail only before Wednesday December 15th 2010. They must be sent to email@example.com and must contain a scientific CV, a letter of motivations, and possibly one or several letter(s) of recommendation. Any questions and requests should be sent to the same e-mail address.
