Forsker på effekten av atmosfæriske partikler på klima, med spesiell fokus på hvordan endringer i utslipp påvirker nedbøren. Studerer også vekselvirkninger mellom aerosoler og skyer, endringer i ekstremnedbør og har tidligere deltatt i prosjekter relatert til geoengineering og kosmisk stråling. Skrev hovedfagsoppgave med tema "global dimming" som gjestestudent ved Københavns Universitet, og fullførte doktorgrad (PhD) i 2015 ved Institutt for Geofag, Universitetet i Oslo, med tittel "On the effect of aerosol emission changes on precipitation and clouds".

Projects

  • 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
  • NAPEX Precipitation is arguably the most direct link between the climate and human society. We depend upon existing precipitation patterns for fresh water and food production, and global infrastructure is designed to withstand current precipitation extremes.
  • 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.
