Jean-François Lamarque is a Senior Scientist with a joint appointment in the Atmospheric Chemistry and the Climate and Global Dynamics Divisions of NCAR. He majored in Physics, graduating in 1987 followed by a Ph. D. in Physics awarded in January 1993, both at the Catholic University of Louvain (Belgium). He came to NCAR in 1990 under a Graduate Research Assistantship of the Advanced Study Program. He has been at NCAR since, except for a one-year position at NOAA-Boulder in 2008-2009. His research interests center on the impact and behavior of atmospheric chemistry in the Earth system and his focus is on long-term trends in atmospheric composition. As part of the Climate Model Intercomparison Project Phase 5 (CMIP5, in support of International Panel on Climate Change Assessment Report #5, IPCC AR5), he has led, in collaboration with D. Shindell (NASA), the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP). He is now a co-chair of the International Global Atmospheric Chemistry (IGAC)/Stratospheric Processes and the Role in Climate (SPARC) Chemistry-Climate Model Initiative. He has led the development of atmospheric chemistry in the Community Earth System Model (CESM) and is currently a co-chair of its Chemistry-Climate Working Group and a member of its Scientific Steering Committee. He is the author or co-author of over 140 peer-reviewed publications, with over 6,000 Web of Science citations. He is also a Lead Author (Chapter 8, Radiative forcing) and Contributing Author (Chapter 6, Carbon and other Biogeochemical Cycles) of the upcoming IPCC AR5.
