The Polar Prediction Project (PPP) is 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 is composed of three phases with the core phase taking place during the period May 2017 to June 2019.
