Senior scientist, Norwegian Institute for Air Research
My main research interest lies in determining the sources and sinks of greenhouse gases (GHGs) and other climate-related atmospheric species, in particular, CO2, CH4, and N2O.
For this, I use a combination of atmospheric measurements and models of atmospheric transport with statistical optimisation techniques to determine the best estimates of the sources/sinks of different atmospheric species.
Moreover, I am trying to improve understanding of anthropogenic emissions and natural sources/sinks and the influence of environmental factors on these. I am also the developer of the Bayesian inversion tool, FLEXINVERT, for the estimation of surface to atmosphere fluxes of atmospheric species.
Nitrous oxide (N₂O) (more commonly known as laughing gas) is a powerful contributor to global warming. It is 265 times more effective at trapping heat in the atmosphere than carbon dioxide and depletes our ozone...
