Welcome to the Atmosphere and Climate group home page. The research team is lead by Associate Professor Annika Seppälä – see here for current and past members.
We do research on atmospheric ozone, Solar influence on the atmosphere, impacts of energetic particles/aurora on the polar regions, chemical-dynamical coupling in the atmosphere, and how this all links to our climate. Our work is computationally intensive and we use satellite data as well as climate simulations to investigate the complex system that is the Earth’s atmosphere. Check out our recent publications.
New era for ozone prediction with GraphCastO3?
Dr Lech Szymanski from Otago School of Computing has developed a short-term ozone prediction model using Message Passing Neural Network (MPNN) and MLS observations with our team. The forecasts are available here: https://o3.cspages.otago.ac.nz/gcast. 2025 season has ended, here is an overview of the observed ozone hole area.
