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.
Jean Froment is a researcher at the climate and research institute NILU.
Jean has conducted his PhD. at the Norwegian institute of Water Research (NIVA) and University of Oslo (UiO) focusing on Effect-Directed analysis (EDA). His post-doctoral experiences at the UFZ (Leipzig, Germany) and Stockholm University (Sweden) focused on performing nontarget analysis of biological and environmental samples.
Jean’s main research interests include the screening of environmental samples (particulate matter, water…) by chromatography (LC, or GC) coupled to high-resolution mass spectrometers (HRMS). Together with in vitro bioassays, nontarget analysis allows the detection of unexpected toxicants in the environment.
Jean is also passionate about the use of open-source software for the data processing of HRMS data and in silico tools to reveal the chemical composition and structure of unknown features.
Dr. Shridhar Jawak possesses nearly 14 years of extensive research experience in Earth observation (EO) and remote sensing (RS) applications, primarily focused on the Earth's cryosphere. Additionally, he has coordination and management experience gleaned from his involvement in research infrastructure projects based in Svalbard. From September 2018 to August 2023, he held the position of Remote Sensing Officer/Senior Adviser at the Svalbard Integrated Arctic Earth Observing System (SIOS), Svalbard, Norway. 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 joining SIOS, 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 multi-satellite data sources such as SAR (Synthetic Aperture Radar), Optical, and LiDAR, as well as airborne data, to discern spatiotemporal changes in the Arctic, Antarctic, and Himalayan regions.
As of September 2023, he has joined NILU, where his 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, as well as the Copernicus Observations In Situ Networking and Sustainability (COINS) project.
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.
