CESM Chief Scientist

Jean-Francois Lamarque

NCAR is pleased to announce that Dr. Jean-Francois Lamarque will become the next Chief Scientist of the Community Earth System Model (CESM), effective 2 March 2014. The Chief Scientist is a very important position that provides the scientific leadership of the CESM project, including service as Chair of the Scientific Steering Committee and oversight of the activities of 12 very active community working groups. Working in partnership with the broader community, the Chief Scientist is responsible for the overall coordination of model development activities and the production of CESM simulations.

Jean-Francois is very well known in the climate and climate modeling communities. He is a Senior Scientist at NCAR, with a joint appointment in the Atmospheric Chemistry (ACD) and Climate and Global Dynamics (CGD) Divisions of the NCAR Earth System Laboratory (NESL).  Jean-Francois currently leads the ACD Global Chemistry Modeling Group and is a co-chair of the CESM Chemistry-Climate Working Group.  He was a Lead Author on Chapter 8 (Radiative forcing) of IPCC AR5. He received his Ph.D. from the Catholic University of Louvain (Belgium) in 1993, when he came to NCAR as an Advanced Study Program Fellow. He has spent his career at NCAR, except for a one-year leave of absence to join the NOAA Chemical Science Division (2008-2009).

Jean-Francois developed the original implementation of interactive tropospheric chemistry in the CESM (CAM-chem), a feature that is now fully supported and used in the community. His research focuses on the use of models to understand the long-term changes of short-lived climate forcers (i.e. ozone, aerosols and methane).  He has published several papers, for instance, on the transient behavior of tropospheric chemistry since the mid-nineteenth century.  Other research interests include the modeling of paleo-atmospheres under massive chemical perturbations.

Jean-Francois takes over the leadership of CESM from Marika Holland (NESL/CGD). We thank Marika for her superb leadership of the project over the past two and one half years. Marika will continue to play a strong role in the CESM project, especially as an internationally-recognized expert on the role of sea ice in the climate system, abrupt high latitude climate change, and polar climate variability and predictability.

Congratulations to Jean-Francois and thank you Marika.
