Biography

Andrew Gettelman is a scientist specializing in clouds and climate change. His work concerns the development and analysis of global model simulations of the climate system with a focus on the development of physical parameterizations of clouds in global climate models and the physics and chemistry of the upper troposphere and lower stratosphere. In addition to developing and managing Earth system models, Gettelman is involved in model evaluation data analysis with satellites and field programs and has served on science teams for both satellite and field projects. Gettelman has been a visiting professor in Physics in Oxford, an Erskine visiting fellow at the University of Canterbury in Christchurch, New Zealand, and a visiting professor in the Institute for Atmospheric and Climate Science at the Swiss Federal Institute of Technology in Zürich, Switzerland. Gettelman came to Pacific Northwest National Laboratory after being a senior scientist at the National Center for Atmospheric Research. Gettelman is the author or co-author on over 200 peer reviewed publications and a textbook (Demystifying Climate Models, Springer). Gettelman has a PhD in atmospheric sciences from the University of Washington and a BS in civil engineering from Princeton University. Click to view Andrew Gettelman's full CV here.
