Professor Ken Carslaw FRS

Ken Carslaw is an atmospheric scientist who researches how aerosol particles affect climate, primarily using numerical models with extensive exploitation of field measurements, laboratory experiments and satellite data.


Ken's research has spanned all regions of the atmosphere. His early research led to the discovery of liquid polar stratospheric clouds down to -90 oC. He pioneered the development of global models of aerosol physical and chemical processes, combining these models with observations to make fundamental discoveries about the origin of aerosol in the atmosphere, the importance of natural aerosol in climate regulation, and the distribution and climatic effects of ice-nucleating particles. Ken is renowned for his application of advanced statistical methods to understand and reduce the persistent uncertainty in how aerosols affect climate.


In 2001, Ken co-founded the journal Atmospheric Chemistry and Physics, which pioneered an open access and transparent peer review publishing model. At the University of Leeds, he has served as Director of Research of the School of Earth and Environment and Director of the Institute for Climate and Atmospheric Science. He was elected Fellow of the American Geophysical in 2019.
