Coloquio – Modelling atmospheric pollution: recent advances with the CHIMERE model

*** Presencial: Sala de reuniones (of 2308 edificio 0+inf) ******

Dr. Sylvain Mailler (LMD / École nationale des Ponts et Chaussées) y Dr. Guillaume Siour (LISA / CNRS)

CHIMERE is a chemistry-transport model that has been developed from 1997 until now by groups in the area of Paris including LMD, LISA and, until recently, INERIS. The model is updated regularly, and a new version is released under the free GPL license every 2 or 3 years. It can be used from hemispheric to urban scale, and represents anthropogenic, biogenic and natural species, in both gaseous and condensed phases. CHIMERE is used to carry out numerous analyses of air pollution cases, future scenarios and parameterization developments. It is also used for operational forecasts in France (PREV’AIR), Europe (CAMS) and other countries. Recent advances in the CHIMERE model, which we will discuss, include the inclusion of new advection schemes, new formulations for pollen emissions, as well as several technical improvements. We will also discuss the status and prospects of the use of the CHIMERE model in South-America.

Guillaume Siour, is a research engineer at CNRS since 2012 and works at LISA on the modeling of chemical and physical atmospheric processes. His PhD was defended in 2012 under the guidance of Isabelle Coll and Augustin Colette, with studies focused on the modeling and impact assessment of European megacities. His expertise is mainly based on the chemistry transport model application and development. He’s involved in CHIMERE model development since 2013 particularly in the areas of atmospheric chemistry and emissions processes. From 2024 he is responsible for coordinating the development of the CHIMERE model. He is author or co-author of more than 70 publications.
Sylvain Mailler is a researcher at Laboratoire de Météorologie Dynamique (LMD, Paris / Palaiseau), and staff of École Nationale des Ponts et Chaussées. His PhD was defended in 2010 under the guidance of François Lott, with studies focused of the dynamical influence of major mountain ranges such as the Tibetan Plateau and the Andes on regional climate. From 2012, he has been working on regional climate of the Mediterranean area and on the development of the CHIMERE model, including works on the horizontal and vertical model grid, advection schemes, the representation of photolysis, and improvements in representation of the settling speed of particles. With Laurent Menut, he has supervised the PhD thesis of Rémy Lapere, who applied the CHIMERE model to the study atmospheric pollution in Santiago, Chile, and its advection to the Andean cryosphere. He is now coordinating the ChimSur International Research Network along with researchers in IFAECI, Instituto Gulich (Córdoba), Universidad de Chile, LMD and LISA.
