Modelling atmospheric pollution: recent advances with the CHIMERE model

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.

¡¡Les esperamos!!
