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.

Dr. Shridhar Jawak is a Project leader/Scientist at the Climate and Environmental Research Institute NILU.

Shridhar possesses more than 15 years of research experience in Earth observation (EO) and remote sensing (RS) applications, primarily focused on the Earth’s cryosphere. He has leadership, coordination and management experience gleaned from his involvement in research infrastructure projects based in Svalbard. Dr. Jawak also served as a steering committee member and project participant in the EEA-funded Cryosphere Integrated Observatory Network on Svalbard (CRIOS) project.

Before moving to Norway, he was a project scientist at the National Centre for Polar and Ocean Research (NCPOR), Goa, India, where he was involved in EO and RS activities in polar science particularly focusing on Antarctica, Himalayas, and the Arctic. Dr. Jawak’s research interests predominantly revolve around remote sensing of the Earth’s cryosphere, with a specific focus on utilizing ground, airborne, and spaceborne sensors to discern spatiotemporal changes in the Arctic, Antarctic, and Himalayan regions.

At NILU his leadership role centers on active participation in a spectrum of ongoing research infrastructure and Earth observation projects within the ATMOS department. These projects include Aerosol, Clouds, and Trace Gases Research Infrastructure (ACTRIS) along with its national node, ACTRIS Norway and spin off projects (ENVRIHUB NEXT, POLARIN, CARGOACT). On the EO side, he is involved in Copernicus In-situ component (COINS) and ESA validation Data centre (EVDC) activities.

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.

Wenche Aas has a Ph.D. in Inorganic Chemistry, and she works on topics related to atmospheric composition and long-range transport of air pollution. She is responsible for the Norwegian monitoring programme of long-range transboundary air pollution on behalf of the Norwegian Environment Agency, and the Ministry of Climate and Environment. Ms Aas is project leader for the atmospheric monitoring programme at Trollhaugen in Antarctica and for the NARE research project "Atmospheric Composition, Processes and Sources of Air Pollution in the Antarctic Environment (AtmosCAir)."

One of Ms Aas' main area of work is within the European Monitoring and Evaluation Programme EMEP on behalf of UN-ECE, where she is responsible for work related to QA/QC and reporting of inorganic compounds, short lived climate forces and heavy metals on behalf of the Chemical Co-ordinating Centre (CCC). She is also responsible for regional data reporting to HELCOM, AMAP and CAMP.

Wenche Aas is member of the Scientific Advisory Group for Precipitation Chemistry (PC SAG) in WMO/GAW.

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.

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 .
