Dr Ekaterina Vorobeva works as a postdoctoral researcher at NILU since January 2024. Her project is a part of the Copernicus Climate Change Service Evolution (CERISE) project that aims to enhance the quality of the C3S reanalysis and seasonal forecast portfolio. In her postdoctoral research, Ekaterina will analyze snow forecasts produced by several leading meteorological centers in Europe and discuss the role of snow in land-atmosphere coupling.

Ekaterina holds a PhD degree from the Norwegian university of science and technology (NTNU) in Trondheim. Her PhD project had a focus on utilizing ground-based observations of low-frequency sound waves (infrasound) to probe the dynamics of the middle atmosphere. A particular emphasis was put on studying gravity waves activity and the stratospheric polar vortex.

Ekaterina’s main research interests include but are not limited to (i) atmospheric dynamics and chemistry, (ii) middle atmosphere, (iii) remote sensing, (iv) atmospheric modelling.

My research interest is quantifying greenhouse gas sources and sinks on regional and global scales. For this, I use a combination of ground- and satellite-based measurements and transport models (FLEXPART and LPDM) with Bayesian inversion techniques.
I am also looking into the effect of changes in sources and sinks on the large climate system.

Dr Knut Breivik works as a senior scientist at NILU and as an adjunct professor in environmental chemistry at the University of Oslo.

His research is motivated by the need to protect environmental and human health from harmful organic contaminants. This calls for a better understanding of relationships between sources and exposure.

Knut Breivik’s main research activities are (i) to develop, evaluate and apply mathematical models to understand and predict production-exposure relationships for these chemicals, (ii) emission inventories, and (iii) long-range transport of harmful chemicals across societies and ecosystems.

Most of his research projects aim to provide environmental authorities as well as international conventions and programs (e.g. EMEP, UNEP and AMAP) with scientific support in their efforts to reduce further environmental and human exposure of these harmful substances.

With over 15 years of experience at NILU, senior scientist Sabine Eckhardt has worked with atmospheric transport modeling since 2006. Her expertise includes the development of the FLEXPART model, widely used to study the transport and dispersion of pollutants in the atmosphere.

Sabine's research primarily focuses on the Arctic, investigating the effects of black carbon and persistent organic pollutants (POPs) and their interactions with climate change. She is studying the deposition of aerosols and their long-term impact on Arctic environments, utilizing data from sources such as ice cores. Additionally, she collaborates with the meteorological institute, forecasting the dispersion of volcanic ash in the event of eruptions.

Her work also extends to the Global Methane Pledge, where she leads a project in the AMAP (Arctic Monitoring and Assessment Programme) framework, addressing the impact of methane on climate change. Sabine co-leads the AMAP expert group on short-lived climate forcers, striving to mitigate the influence of pollutants that accelerate climate warming.
