Andrew Gettelman, an Earth scientist at Pacific Northwest National Laboratory (PNNL), was named a Fellow of the American Geophysical Union (AGU). Gettelman and 53 others will be honored at AGU’s Fall Meeting 2022.

“I’m excited and honored to be named an AGU Fellow,” said Gettelman. “AGU has done a lot for my career and I’m excited to join some of the colleagues I respect the most as a fellow.”

AGU Fellows are recognized for their outstanding achievements and contributions to Earth and space science. The distinction is awarded “of remarkable innovation and/or sustained scientific impact.” AGU Fellows provide leadership across different geosciences fields.

Gettelman studies clouds and climate change. His work centers on developing representations of atmospheric processes for and analyzing the results of climate model simulations. He specifically focuses on representations of clouds as well as the physics and chemistry of the lower atmosphere.

“Dr. Gettelman has worked to try to improve model formulations of physical processes, especially cloud and aerosol processes, for studying climate change,” said PNNL Laboratory fellow Yun Qian. “He is a pioneer and world leader in understanding cloud microphysics, including representing clouds and their climate impacts across scales. The Morrison-Gettelman Cloud Microphysics Scheme he developed has been used by thousands of scientists around the world in different regional and global climate models.”

An author of over 200 peer-reviewed publications, Gettelman joined PNNL in 2022. Prior to coming to PNNL, he was a senior scientist at the National Center for Atmospheric Research. Gettelman has been a visiting professor in Physics at Oxford, an Erskine visiting fellow at the University of Canterbury in Christchurch, New Zealand, and a visiting professor at the Institute for Atmospheric and Climate Science at the Swiss Federal Institute of Technology in Zürich, Switzerland. Gettelman has a PhD in Atmospheric Sciences from the University of Washington and a BS in Civil Engineering from Princeton University.
