September 2024

The new leadership of the Oeschger Centre has been in office since 1 August 2024. Karin Ingold (Policy Analysis and Environmental Governance group) is the new President and Stefan Brönnimann (Climatology group) is the new Vice President of the OCCR. In her welcome message on the OCCR website, the new president writes: “The OCCR's multidisciplinary approach allows us to tackle various critical issues, including ocean heatwaves, urban climate, hail, climate extremes, climate justice and numerous physical, natural and social tipping points. Our research is focused on advancing academic knowledge in interdisciplinary climate science and meeting the needs and demands of society.”
There have also been changes to the OCCR's Scientific Advisory Board. Hubertus Fischer (Past Climate and Biogeochemical Studies on Ice Cores Group group) has been a new member since 1 August.

New OCCR research clusters

cluster schema

At their retreat earlier this year, the leaders of the 40 OCCR research groups decided to organise research at the OCCR into six new thematic clusters and two platforms (technology, methods). The titles of these new organisational elements are

Clusters

  • Earth System Processes
  • Extremes, Tipping Points and (Managing) Risks
  • Climate Justice
  • Climate, Health and Cities
  • Biodiversity, Ecosystem Health
  • Societal Transition & Resilience

Platforms

  • Earth System and Climate Modeling
  • (Climate) Data Science and Analysis

Cluster workshops will be held before the end of this year to capture the science and profile and develop a roadmap of activities.

SNSF Lead Agency Grant

The Atmospheric Processes and Radiometry group has obtained an SNSF Lead Agency Grant for a project in collaboration with the University of Augsburg and the German Aerospace Center in Oberpfaffenhofen in which it has the consortia lead. The project is called GIGAWATT and will start in early 2025. It aims to set up a unique alpine observatory to monitor the atmosphere from the tropopause to the mesosphere, and it wants to measure winds and temperatures and study gravity wave dynamics at the MLT using tomographic techniques. It is planned to install a Swiss meteor radar and a FAIM all-sky camera with airglow camera in Zimmerwald. A total of three postdocs and one doctoral student will be funded as part of the project.

Effective solutions to regulate plastics

The Policy Analysis and Environmental Governance Group has secured funding for a new project of the Swiss Network for International Studies (SNIS). The project is entitled ‘Getting beyond the mess: Investigating effective solutions to regulate plastics’ and brings together researchers from the OCCR (project leader Marlene Kammerer), EAWAG, ETHZ, Empa and various institutions in Bhutan. Plastic is a problem because of the high CO2 emissions generated during its production, among other things. Excessive production, overconsumption and incorrect waste management cause health and environmental issues on a global scale. This is why a new multilateral agreement on plastics (UN Plastics Treaty) is currently being negotiated.  While initial attempts have been made to assess plastics policies worldwide, there is still a lack of systematic assessments and comparisons, particularly regarding barriers to implementation and stakeholder perspectives. This project aims to close this research gap.

New professor for Experimental Climate Physics

Eliza Harris

Eliza Harris has joined the OCCR as a new professor for Experimental Climate Physics. She succeeds Markus Leuenberger, who will retire early next year, and will also become the new Director of the Research Stations Jungfraujoch and Gornergrat. Eliza is a biogeochemist interested in greenhouse gas cycles and in particular the nitrogen cycle but has also comprehensive experience in data sciences. She graduated from the University of Tasmania in Antarctic Sciences before completing her PhD at the Max-Planck-Institute for Chemistry in Mainz working on sulfur isotopes to understand SO2 oxidation.

During postdoctoral stays at MIT, Empa and later as Research Associate at the University of Innsbruck, she specialised in the use of (site specific) N2O analysis to understand the processes going on during biogenic N2O production. Over the last 3 years, she further developed her expertise in Data Sciences working as Senior Scientist at the Swiss Data Science Center in Zurich.

SNFS Consolidator Grant

Christoph Schwörer

SNSF Ambizione Grant I

Hilla Gerstmann

Hilla Gerstmann has been awarded an Ambizione Grant and will become part of the Mobiliar Group for Climate Impact Research. She holds a PhD in Atmospheric Dynamics from the Weizmann Institute of Science, Israel and is currently working as a Postdoc at the University of Lausanne and at ETH Zurich. Her Ambizione project is called "Forecasting midlatitude storm impacts beyond current predictability limits". The goal of the project is to improve the prediction of extreme winter storms in the North Atlantic and Europe over sub-seasonal to seasonal time scales - ranging from two weeks to two months.

By using state-of-the-art idealised climate models, statistical methods and machine learning, as well as risk assessment models, the project aims to identify key atmospheric factors and precursors that drive the frequency and intensity of mid-latitude storms.

SNSF Ambizione Grant II

Fabrice Lacroix

Fabrice Lacroix has joined the OCCR as an SNSF Ambizione Fellow in the Geocomputation and Earth Observation group. The awarded project will assess future changes of the pan-Arctic Nitrogen feedback. The project focuses on determining the impacts of increased nitrogen release from permafrost thaw for pan-Arctic vegetation growth, as well as for the emission of the important greenhouse gas N2O. The project aims to advance state-of-the-art terrestrial biosphere modelling in the field of Arctic change while incorporating data provided from current field campaigns.

The interdisciplinary environment of the OCCR provides the perfect framework for the connection of different research areas touched by the project.

Dorra Gharbi is a new Postdoc with the Paleoecology group. She completed a PhD in Aerobiology at the University of Malaga, Spain. Earlier, she received an engineering degree in Natural Resources Management and an MSc in Plant Breeding. Her research is about aerobiology (pollen and fungal spores analysis), their relationships with air pollution and meteorology, phenology and climate change influence. Dora is part of a new research project funded by Innosuisse, the Swiss Innovation Agency. The project "MARVEL–Emerging data services based on real time pollen monitoring” is a collaboration between partners from industry (Swisens AG) and research (METAS, FHNW, UniBE). The primary aim of the project is to provide allergy sufferers worldwide with real-time information and short-term forecasts of allergenic pollen in the air. For this, the project will combine a new measurement device with artificial intelligence to identify and quantify airborne pollen.

Hendrik Grosselindemann is a new PhD student with the Ocean Modelling group. He did a Master in Climate Physics at the GEOMAR Helmholtz Center for Ocean Research in Kiel, Germany with a thesis entitled “Long-term variability of Agulhas Leakage and its embedding into the global overturning”.
