International Coordination Office for Polar Prediction (ICO)

The International Coordination Office for Polar Prediction (ICO) supports the Polar Prediction Initiative which is an undertaking by WWRP (World Weather Research Programme) together with PCPI, the Polar Climate Predictability Initiative by WCRP (World Climate Research Programme).

The ICO is hosted by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) having entered into a Memorandum of Understanding with the WMO

Helge Goessling is a physicist specialized in climate modelling and polar prediction, with a particular focus on sea ice prediction and verification. Serving as director of the PPP/YOPP coordination office since 2014, he is involved in a broad range of YOPP-related activities, ranging from modelling and forecasting via the polar observing system to user engagement, education, and dissemination.

Kirstin Werner (Project Officer)

During her PhD and postdocs at GEOMAR (Kiel, Germany), the Institute of Arctic and Alpine Research (Boulder, Colorado, USA), and the Byrd Polar and Climate Research Center (Columbus, Ohio, USA), Kirstin Werner studied high-resolution sediment cores from the eastern Fram Strait in order to understand the variability of heat transfer to the Arctic Ocean and corresponding changes in the sea-ice extent during the past ca 12,000 years. While currently completing her on-the-job masters program in science marketing at the Technical University Berlin, Kirstin returned back to Germany now focusing on the science management aspects of short-term polar weather and climate variability during the Year of Polar Prediction.

Richard Swinbank is WMO consultant to the Polar Prediction Project. Before joining PPP, he spent most of his career at the Met Office, Exeter, UK, where he managed the ensemble forecasting research group. His research interests include dynamical meteorology, data assimilation and numerical modelling. Richard was co-chair of the GIFS-TIGGE working group, which coordinated the TIGGE project that was a major component of the THORPEX research programme, and founding co-chair of the WWRP working group on Predictability, Dynamics and Ensemble Forecasting. He leads the YOPP Modelling Task Team and is a member of the Data Task Team.
