Greg McFarquhar | University of Oklahoma

Greg McFarquhar is the Director of the University of Oklahoma Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) and a Professor in their School of Meteorology. McFarquhar comes from the University of Illinois at Urbana-Champaign where he was a faculty member in the Department of Atmospheric Sciences from 2001-2017. He has also served as a visiting faculty fellow at NCAR from 2015 to 2016.

Chris Bretherton | University of Washington

Chris Bretherton is an atmospheric scientist who studies cloud formation and turbulence and improves how they are simulated in global climate and weather forecast models. His research includes participating in field experiments and observational analyses, three-dimensional modeling of fluid flow in and around fields of clouds, and understanding how clouds will respond to and feed back on climate change. Computer code developed by his research group for simulating cloud formation by atmospheric turbulence is used in the two leading U.S. climate models.

Robert Wood | University of Washington

Clouds have fascinated us for thousands of years, but their natural beauty belies a tremendous complexity that continues to elude a complete theoretical understanding. Rob Wood is a physicist who tries to increase that theoretical understanding, studying cloud systems and the meteorological processes that govern them. Using observational data, he builds models of cloud structures and behaviors, exploring the links between clouds and meteorology over the oceans.

Roj Marchand | University of Washington

Dr. Marchand's research focuses on cloud microphysics and improving the representation of clouds in climate and cloud resolving models. This includes developing cloud property retrievals based on satellites and ground-based systems (especially radar), validating retrievals using airborne in situ observations, developing instrument simulators for models, comparing model clouds with retrieved properties, and recently, developing an adaptive vertical grid for cloud resolving models in order to improve the simulation of boundary layer clouds.
