Dr. Karl Espen Yttri is a senior scientist at NILU with a Ph.D. in aerosol science. He has extensive expertise in atmospheric aerosols and their chemical composition across diverse environments, ranging from urban areas to the pristine Arctic and Antarctic.

His primary focus is on carbonaceous aerosols, using both on-line and off-line methodologies for the source apportionment of anthropogenic and natural aerosol sources. This includes developing analytical methods for carbonaceous aerosol, including source-specific organic tracers.

As a member of the Chemical Coordinating Centre of the European Monitoring and Evaluation Programme (EMEP) at NILU, he contributes to research on the long-range atmospheric transport of aerosol particles.

Karl Espen Yttri has 71 publications at NILU:
