Léa Prévost


I am a first year PhD student in the Atmospheric Chemistry and Aerosol research group, in the Institute for Climate and Atmospheric Science (ICAS). I am funded by the NERC Panorama DTP and the Met Office are CASE partners for my PhD project.

In 2023, I completed an MSci in Physics and Astronomy at the University of Glasgow. My research focused on solar physics, with projects supervised by Prof Lyndsay Fletcher and Dr Nicolas Labrosse. After studying the solar atmosphere, I decided to pursue a PhD in (terrestrial) atmospheric physics at the University of Leeds.

Research interests

My research focuses on advancing our understanding of aerosol effects on Earth's climate, specifically addressing uncertainties in climate models. Human-induced aerosol emissions play a crucial role in mitigating global warming, but the magnitude of their impact remains uncertain. I aim to develop innovative methods to distinguish between structural model deficiencies and parametric uncertainties in aerosol models.

By comparing extensive observations with climate models, my work seeks to identify and address structural errors, going beyond traditional approaches that have struggled to disentangle these uncertainties. The ultimate goal is to contribute to the refinement of Met Office climate models, and improve our understanding of aerosol radiative forcing to enable more robust climate predictions.
