Getting Involved with the Year of Polar Prediction

Scientific Involvement


Join a Task Team

Task Teams for various activities during the Year of Polar Prediction have been formed. Read more about YOPP Task Teams at In order to get engaged in one of the Task Teams, please contact the ICO at

Request YOPP Endorsement

Projects, programmes, and initiatives contributing to the aims of the Year of Polar Prediction are invited to request endorsement by YOPP. Learn more about YOPP Endorsement at

Benefit from YOPP-related modelling datasets (and/or contribute yours)

Near-real time forecast data to be used during the YOPP Core Phase:

"YOPP Dataset" by ECMWF: analyses & deterministic forecasts; 9 km resolution; extra variables;

little delay (at request <1d); starting mid-'17

• GOV sea-ice forecasts (short-term) by multiple centres; already running; availability to be discussed

Reanalyses and other non-real-time data:

• "YOPP Reanalysis" by ECMWF; extension of "CERA-SAT"; (weakly) coupled DA; atmos 65 km 137lev,

ocean ¼° 75lev; 10 ens. members

• Arctic System Reanalysis v3; Polar WRF; 5 km resolution, lowest level at 2 m; lateral forcing by ERA5

• CBHAR: high-resolution reanalysis for the Pacific Arctic

• Sea-ice ocean reanalyses (PORA-IP); S2S; TIGGE; Drift Forecasts.

Take part in the YOPP observational component

Before and during the YOPP Core Phase:

• Share your field plans with us (ideally via YOPP endorsement) to generate opportunities

• Submit your research data, where applicable and possible, to the GTS

• Take extra observations that help "filling the gap", in particular during Special Observing Periods incl. radiosondes, AWS, buoys, drifters, airborne platforms etc.

During and after the YOPP Core Phase:

• Make your data accessible through the YOPP Data Portal

• Use other YOPP data for your research.

Submit data in real-time

If you need assistance to submit your data into the WIS GTS, please get into contact with the ICO so we connect you with an WIS/GTS expert.
