Research project

Like all economic sectors, air traffic contributes to CO2 emissions and climate change, but the magnitude of this contribution remains uncertain and subject to scientific debate. Aircraft emit not only CO2 but also water vapour in the upper troposphere. Under favourable meteorological conditions, water vapour emissions can induce the formation of condensation trails (contrails) that can be seen in the sky. These contrails may persist for several hours and can evolve to form cirrus clouds. The climate impact on contrails and contrail-induced cirrus is very uncertain.

 

This jobholder will parametrise the sub-grid scale variability in water vapor in the upper troposphere and the formation of contrails and contrail-induced cirrus in the LMDZ atmospheric general circulation model. This modelling phase will be followed by a detailed validation study using a unique observational dataset of contrails and contrail-induced cirrus from the SIRTA experimental site. The parametrisation for contrails and contrail-induced cirrus will then be coupled to air traffic inventories to estimate the radiative and climatic impacts of aviation.

 

This work is expected to contribute to the development and improvement of physical parametrisations in the LMDZ model and should lead to several high-level scientific publications.

 

About the research project

This post-doctoral position is funded by the Direction Générale de l'Aviation Civile (DGAC) under the IMPACT project. It involves five partners: the Laboratoire Image Ville Environnement (LIVE), the Laboratoire de Météorologie Dynamique (LMD), the Centre Européen de Recherche et Formation Avancée en Calcul Scientifique (CERFACS), Météo-France and the SNECMA company.
