Personal profile

Research

Short-lived climate forcers and their impacts on air pollution, climate, and human health

Profile

I am working on global to regional atmospheric modelling for more than twenty years. I have been involved in large international projects focusing on short lived climate forcers and their impacts on air quality and climate, as well as on health impacts of air pollution and their economic valuation. My main area of interest is on the natural sources of SLCFs and their interactions with anthropogenic SLCFs and climate.

Cooperation and dissemination

Coordinator, WP leader and partner PI in several EU projects. Contributed to climate assessments under the Arctic Monitoring and Assessment Programme. Part of the CMIP7 Atmosphere and Impacts & Adaptation data request and author teams.
