Physicist and science disseminator, broad experience in atmospheric science and global climate modelling.

Physicist, climate scientist, science disseminator. Studying precipitation and the role of atmospheric aerosols in a changing climate, mainly through climate modelling. Regular newspaper columnist and science commentator, Norwegian media. Previously worked on particle physcis, with the ATLAS collaboration at CERN and the BRAHMS collaboration at RHIC. PhD in Nuclear Physics, University of Oslo (2006).


  • AC/BC In search of airborne soot, and how it affects the climate
  • The NetBC project Black carbon: A challenging piece of the climate puzzle
  • Impact of absorbing Aerosols on Radiative forcing in the European Arctic The climate impact of absorbing aerosols, such as black carbon particles originating from fossil fuel combustion or biomass burning, mineral dust and volcanic ash, is still very poorly understood especially its role in the atmosphere of polar regions.
  • ICOS-Norge Integrated Carbon Observation System (ICOS)-Norway and Ocean Thematic Centre (OTC)
  • SUPER - SUb-daily Precipitation Extremes in highly-populated Regions The main objective of SUPER is to quantify the influence of anthropogenic activity on sub-daily extreme precipitation in highly populated regions
  • Sensible heat has significantly affected the global hydrological cycle over the historical period Multiple lines of evidence indicate widespread changes to the global water cycle since 1950. Here we show, using a range of climate modelling results, that changes in sensible heat are the dominant contributor to the present global-mean precipitation change since preindustrial time.
  • ACRoBEAR – high-latitude risk of wildfire and disease The ACRoBEAR (Arctic Community Resilience to Boreal Environmental Change: Assessing Risks from fire and disease) project will quantify changing risk of boreal forest fire and natural-focal disease for local communities in high northern latitudes under changing environmental and climatic conditions.
  • ACACIA – Advancing the Science for Aviation and Climate The EU-funded project ACACIA (Advancing the Science for Aviation and Climate) aims to provide improved scientific knowledge of the non-CO2 impacts from aviation emissions of relevance for the development of harmonised policies and regulations for a more climate-friendly aviation system.
  • AVIATE: How can aviation contribute to a low-carbon society? The AVIATE (Aviation in a low-carbon society) project will provide better understanding of the climate impact of aviation, both for Norway and globally, and explore options for reducing that impact.
  • ChiNorBC This project will help enhance the knowledge base for and support the development of a strategy for BC/OC co-control in China.
