Company Profile

The CNRS (National Center for Scientific Research) is a government-funded research organization, under the administrative authority of France’s Ministry of Research. As the largest fundamental research organization in Europe, CNRS carried out research in all fields of knowledge. The present project involves researcher scientists from the Joint Research Unity, UMR7362 LIVE (Laboratoire Image, Ville, Environnement), of CNRS and University of Strasbourg. This JRU studies urban processes including urban management, environmental risks (especially air pollution modeling), risks management and quality of life. The research team involved in the present project is part of the EPAC team (“Energy, Air Pollution and Climate”). The team especially focuses on traffic emissions, urban meteorology, building energy consumption, and air pollution modeling at various scales. The objective of the team is to develop operational methodologies (especially models) for helping Energy and AQ assessment. The principal investigator in HIKARI at CNRS is Dr. D. Hauglustaine. He has been involved in the development of a fully coupled chemistry-climate model. The model is the result of the coupling of the well-established LMDz general circulation model with the chemistry and aerosol model INCA (INteraction with Chemistry and Aerosols). LMDz-INCA accounts for long-lived greenhouse gases, ozone chemistry, and the different types of aerosols on-line in a coupled atmosphere-biosphere GCM. The model has already been used in the framework of several European projects, including, for the impact of aircraft emissions on composition and climate, TRADEOFF and QUANTIFY. Dr D. Hauglustaine will be seconded in HIKARI by Dr R. Valorso. He has worked on atmospheric chemistry modelling with a focus on gaseous chemistry and particles formation in the atmosphere.

Contribution to HIKARI

The CNRS work in HIKARI will be to evaluate the global impact of aircraft emissions on atmospheric composition and climate, with a focus on H2O and NOx using LMDz-INCA model. LMDz-INCA has recently been upgraded to model the atmosphere up to 60 km. Stratospheric chemistry will soon be upgraded for ozone chemistry. Using different scenarios provided by the partners, the impact of different fleets of high speed aircraft on climate will then be evaluated. A common analysis of the results will be performed by CNRS and DLR.
