Cynthia H. Whaley, PhD

Research Scientist

Research scientist with CCCma, working on development and applications of short-lived climate pollutants in the CanAM_GEM climate model.

Formally a physical sciences specialist with ARQI, working on research and development with the GEM-MACH air quality model.

Current research and/or projects

Research of climate and air quality issues using Environment and Climate Change Canada's climate model, CanAM_GEM, and air quality forecasting model, GEM-MACH.
