CISL Seminar Series - Building and Using CESM2

Mesa Lab Main Seminar Room

Jean-François Lamarque

10:00 am - 11:00 am

In this presentation, I will first describe the process through which the new version (version 2) of the Community Earth System Model (CESM) came to fruition, a process that took approximately 2 years.  In the second part of my talk, I will focus on the upcoming large-scale use of CESM2 in the context of the Coupled Model Intercomparison Project (CMIP). I will end my presentation with a discussion of forthcoming challenges and opportunities in climate modeling.

Jean-François is a Senior Scientist at NCAR with a joint appointment in the Atmospheric Chemistry Observations and Modeling (ACOM) and Climate and Global Dynamics (CGD) Laboratories.  He is the current Community Earth System Model (CESM) Chief Scientist.  He is also head of the Modeling Section in ACOM. He was a Lead Author on Chapter 8 (Radiative forcing) of IPCC AR5, published in 2013. He is the author or co-author of over 200 papers. He received his Ph.D. from the Catholic University of Louvain (Belgium) in 1993, with Pr. Berger and Dr. Brasseur as joint advisors.  He was an ASP postdoc 1993-1995.  He has worked at NCAR since then, except for a one-year leave of absence to join the NOAA Chemical Science Division (2008-2009).

He has developed the original implementation of interactive tropospheric chemistry in the CESM (CAM-chem), a feature that is now fully supported and widely 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 on the transient behavior of tropospheric chemistry since the mid-nineteenth century.  In particular, he has made use of ice-core measurements of black carbon and sulfate aerosols to validate model simulations of those compounds. Other applications include the modeling of paleo-atmospheres under massive chemical perturbations.
