Research topics
The team is coordinated by Laurent Menut. 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.

Impact of climate on renewable energies

The InTRo team also contributes to interdisciplinary work at the interface between atmospheric and climate sciences and energy economics and engineering. A first line of research of the team in this field deals with the potential, predictability and value of the Variable Renewable Energy (VRE, mainly wind and solar) ressource. It involves understanding the variability and trends of the VRE potential in association to dynamical and thermodynamical processes at scales ranging from the boundary layer to the planet; reexamining the statistical modelling of instant VRE value; improving sub-seasonal to seasonal prevision of VRE by combining dynamical and statistical models and estimating the economic value of such previsions. A second line of research is concerned with the long-term increase in the sensitivity of the energy system to meteorological conditions associated with increasing VRE penetration and with rising demand thermosensitivity due to electrification. These activities are underpinned by interdisciplinary collaborations within the Energy4Climate center.

Chemistry-transport from urban to hemispheric scales

The study of the atmospheric composition is an important research topic in the InTRo team. In particular, the team coordinates the development of the CHIMERE chemistry-transport model, which is largely used in France and abroad for research and operational air quality simulations, including the French and European forecast platforms Prev'Air and CAMS. The main topics of research in this field include wildfire emissions with the development of the emifiresCAMS code, mineral dust emissions from arid areas and their subsequent transport, the transport of volcanic plumes as well as the development of downscaling techniques to address urban scale atmospheric pollution and population exposure with the EXPLUME model.
