Supporting international coordinated research efforts in the polar regions that have undergone significant changes in recent years is the goal of the World Meteorological Organization's (WMO) Polar Prediction Project (PPP) within the World Weather Research Programme (WWRP). The mission of the PPP is to

"promote 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 - the Year of Polar Prediction - is one of the flagship activities within PPP. The YOPP core phase (mid-2017 to mid 2019) is approaching. Read more....

YOPP Data Portal

The YOPP Data Portal yopp.met.no is currently under development in the context of the Year of Polar Prediction. 

The YOPP Data Portal to be accessed at yopp.met.no will provide metadata and links to respective data sets generated during the Year of Polar Prediction. As a legacy for YOPP, this data portal is going to take into account the various requirements of end-users working with the YOPP data collection. More information can be found here.

Polar Prediction Matters

Polar Prediction Matters (PPM) is a non-peer reviewed forum initiated as a means to foster the dialogue between those that research, develop, and provide polar environmental forecasts and those that use (or could use) polar environmental forecasts to guide socio-economic decisions.

From mid-2017 through mid-2019 – the Year of Polar Prediction Core Phase – PPM will feature written contributions that provide a range of individual views on how polar environmental forecasts (and other environmental information, e.g., satellite imagery) are actually used, whether additional needs exist, and what factors might limit the effective use of forecasts.

The YOPP Infographic

During the Core Phase of the Year of Polar Prediction (mid 2017 – mid 2019), observations will be enhanced in polar regions by means of radiosondes, satellites, buoys, aircraft etc. The obtained data will be used  to improve polar weather and sea ice forecasts to be used by those operating in the high latitudes.

The International Coordination Office for Polar Prediction (ICO) and the Alfred Wegener Institute have produced a YOPP infographic illustrating what is going on during the Year of Polar Prediction. See the YOPP infographic in full size here

Science Workshops

A joint workshop on sea ice modelling, data assimilation and verification will be held from 1–3 November 2017 at the Nansen Environmental and Remote Sensing Center (NERSC) in Bergen, Norway.

The workshop builds on a series of previously successful workshops by the IICWG Data Assimilation Working Group to advance international capabilities for automated sea ice analyses and prediction on timescales from hours to season. Read more...

Getting involved

There are many options to get involved with the Year of Polar Prediction. Read more about ways to engage with YOPP here.

Mailing List

polarprediction@climate-cryosphere.org is a mailing list for anyone interested in polar weather and climate prediction and predictability supported by CliC and PPP. To subscribe please send an e-mail to office@polarprediction.net


We support and organize webinars, workshops and other events. The first-ever Polar Prediction School was held in April 2016 at the Abisko Scientific Research Station in northern Sweden. A second Polar Prediction School is currently under planning. Find more information about the YOPP Education Task Team here.
