Dr. Nikolaos Evangeliou is a Senior Scientist at NILU’s Atmospheric and Climate Research department (ATMOS). He has a PhD in Chemistry and has been working previously with radiochemical analyses of environmental samples followed by nuclear measurements.

Since 2014, when he joined NILU, he has been working with atmospheric dispersion modelling of conventional and radionuclide substances emitted after nuclear accidents and their impacts on human and non-human biota. He currently works with source emission optimisation of aerosols and gases using Bayesian inversion tools.

Since 2018 he is a board member of the Nordic Society for Aerosol Research .

Dr. Rona Thompson is a senior scientist at NILU, Kjeller, since 2011. 

Dr. Thompson has a PhD in atmospheric chemistry from Victoria University of Wellington, New Zealand. Since completing her PhD, Thompson has been a post-doc at the Max Planck Institute for Biogeochemistry in Jena, Germany, and at the Laboratory for Climate and Environmental Sciences in Saclay, France. 

Dr Thompson’s main research interests are in understanding the sources and sinks of atmospheric pollutants, including greenhouse gases, and the processes driving these. For this, she employs atmospheric transport models and statistical methods. 

Dr Thompson has a long experience working with, and developing, numerical models for atmospheric research. She is also the developer of the atmospheric inversion framework, FLEXINVERT. 

Dr Thompson is actively involved in Norwegian and European research projects and is currently the coordinator of the Horizon Europe project, EYE-CLIMA. She is also the co-leader of the Global Carbon Project N2O Budget activity.

Kjetil Tørseth received his Dr Scient  degree at NTNU-Trondheim, and has worked at NILU since 1992.Since 1999 he has served as department head/research director.

His expertize includes measurements and data management and assessment of precipitation chemistry, reactive gases, aerosols and climate forcers, and their associated effects on ecosystems, health and climate.

He is engaged in a wide range of programs addressing assessments of air pollution on regional and global scales, including EMEP (head the EMEP Chemical Coordinating Centre), WMO Global Atmosphere Watch (GAW Country contact of Norway, member to the Scientific Advisory Group on Reactive Gases, responsible for the two GAW World Data Centers on Aerosols (GAW-WDCA) and Reactive Gases (GAW-WDCRG). He is also engaged in several research infrastructure activities like ICOS, ACTRIS and SIOS. He has a broad experience from many international research and capacity building projects.

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.

Dr. Yvan Orsolini joined NILU in March 1998 as a senior researcher posted at Kjeller, Norway. 

He earned his MSc. in Atmospheric Sciences from the University of Illinois (Urbana, USA) and his PhD is in geophysics from the University of Washington (Seattle, USA). He has worked with dynamics, chemistry and remote sensing of the middle atmosphere and, in particular, with the Earth’s ozone layers and the solar radiative and particle impacts on the atmosphere. 

Another area of research is cryosphere-atmosphere interaction, in particular the role of snow and sea ice in the climate system and in seasonal predictions. 

He has a long experience working with general circulation models, either atmosphere-only or coupled ocean-atmosphere models, including whole-atmosphere models (such as WACCM) which extends into the lower thermosphere, as well with seasonal prediction systems. He has also contributed to the analysis of numerous satellite remote sensing datasets (UARS, SABER, ENVISAT, MLS, SOFIE,…), and atmospheric re-analyses regarding dynamics or composition. 

He has coordinated one European project and several Norwegian Research Council projects on behalf of NILU, while participating to numerous other projects. He was affiliated part-time (20%) with University of Bergen (2010-2020) and with NTNU (2020-2023). 

His h-index is 40, with over 5000 citations (Google Scholar).
