Members of the InTro group study the physical and chemical properties of the troposphere and its interfaces. Our scientific interests include :

• Regional climate and water cycle
  Study of the Water cycle in InTRo is focused on the Mediterranean region, in the framework of international initiatives HyMEx and MedCORDEX, but also in the basins of the major Chinese rivers. In the Mediterranean area, studies of the hydrological cycle and hydrological extremes (extreme precipitation, dry spells) has relied in part on the RegIPSL regional coupled modelisation platform, under development in the InTRo team in collaboration with other IPSL teams. Scientific focuses in the team include interactions between aerosols and precipitation, studying the runoff of major hydrologic basin including major Chinese rivers for which anthropogenic use of the water is critical. Study of the regional water cycle is one of the strong reasons why the InTRo team is currently strongly involved in the development of the RegIPSL regional coupled model.
• Chemistry-transport from urban to hemispheric scales
  Chemistry-transport and study of atmospheric composition is an important matter of study for the InTRo team. In particular, the team is at the heart of the development of the CHIMERE chemistry-transport model, which is largely used both in France and abroad for research and for operational air quality simulations, including French national previon program Prev’Air and European prevision platform CAMS. Scientific focuses in the team include studying wildfire emissions, including the development of the APIFLAME model, studying the mineral dust emissions from arid areas and their subsequent transport, as well as transport of volcanic plumes.
• Impact of climate on renewable energies
  A recent topic in InTRo, the activities of the team in this field deal with understanding the variability and trends of the windmill production potential, including reexamination of the statistical modelling of instant wind value, studies of the feasibility and added value of seasonal prevision of the wind, and decadal-scale studies involving long-term trends and the impact of air-sea coupling on the aeolian potential. These activities are part of the TREND-X program that unites the efforts of ten École Polytechnique laboratories under the leadership of LMD. In collaboration with INRIA, the WINDPOS software for lagrangian stochastic modelling of wind has been developed and includes the effect of the windmill farms on the wind field itself.
