The Polar Prediction Project (PPP) was a 10-year (2013–2022) endeavour of the World Meteorological Organization’s (WMO) World Weather Research Programme (WWRP) with the aim of promoting cooperative international research enabling development of improved weather and environmental prediction services for the polar regions, on time scales from hours to seasonal.

The Year of Polar Prediction (YOPP) is the flagship activity of PPP with the aim of enabling a significant improvement in environmental prediction capabilities for the polar regions and beyond, by coordinating a period of intensive observing, modelling, verification, user-engagement and education activities.

The Year of Polar Prediction was composed of three phases with the core phase taking place during the period May 2017 to June 2019.

On 31 December 2022 the ten year Polar Prediction Project (PPP) came to an end along with its flagship activity the Year Of Polar Prediction (YOPP). Whilst PPP and YOPP have now finished, three key groups will continue for at least 2023, these are the Model Intercomparison and Improvement Project (MIIP) led by Prof Gunilla Svensson from the University of Stockholm, the Year of Polar Prediction in the Southern Hemisphere (YOPP-SH) led by Prof David Bromwich from the Byrd Polar Institute at Ohio State University and the PPP Societal and Economic Research Applications group (PPP-SERA) led by Prof Machiel Lamers from the University of Wageningen in the Netherlands. The recording of the plenary discussions from the YOPP Final Summit (see also yoppfinalsummit.com for further details) can be found at the YOPP Youtube Channel https://www.youtube.com/@yearofpolarpredictionpolar6442. Researchers are encouraged to review the PPP/YOPP related publications available via the YOPP google scholar account (https://scholar.google.de/citations?user=tbR5tOAAAAAJ&hl=en) and where appropriate include PPP/YOPP in your publications as per the recommendations at https://www.polarprediction.net/publications/yopp-acknowledgement/

The Polar Prediction Project Steering Group and the International Coordination Office located at AWI thank you for your interest in and support of PPP/YOPP over the last ten years and wish you future success in your efforts in Polar Prediction.
