SIPN2 Webinar: Call for Registration
The Sea Ice Prediction Network-Phase 2 (SIPN2) announces an upcoming webinar, entitled "Prospects for Improved Regional Predictions of Arctic Sea Ice" that will be presented by Mitch Bushuk at the Geophysical Fluid Dynamics Laboratory (GFDL). This webinar will provide an overview of a newly developed dynamical seasonal prediction system and its performance in predicting regional Arctic sea-ice conditions. The one-hour webinar will be held on Tuesday, 13 July 2021, starting at 9:00 a.m. (AKDT).
Call for Sea Ice Outlook Contributions
The Sea Ice Prediction Network–Phase 2 (SIPN2) Project Team announces the Call for Contributions to the 2021 Sea Ice Outlook (SIO) June Report (based on May data). The SIO provides an open process for those interested in Arctic sea ice to share ideas. The monthly reports contain a variety of perspectives—from advanced numerical models to qualitative perspectives from citizen scientists. Post-Season reports focus on performance of the Outlooks, analysis and discussion of factors driving sea ice extent, and scientific methods for predicting seasonal conditions.
Submission Deadline: 6:00 p.m. (AKDT) Friday, 11 June 2021 (firm).
2020 Sea Ice Outlook Post-Season Report Now Available
The 2020 Sea Ice Outlook (SIO) Post-Season Report is now available online. The SIO is a community network activity led by the Sea Ice Prediction Network-Phase 2 (SIPN2) Project Team with contributions from key partners. This report includes in-depth discussions and analysis of factors impacting sea ice this past summer, the SIO contributions, regional observation, predicted spatial fields, Antarctic contributions, seasonal sea ice forecasting for the Alaska marine shipping industry, and a summary from the Sea Ice Drift Forecast Experiment (SIDFEx). This report also includes a discussion of lessons learned from the SIO Contributors Forum, and discussions regarding probabilistic assessment of the 2008-2020 Outlooks and an evaluation of SIO forecast skill relative to control forecasts.
SIO Contributors Forum
The SIPN2 leadership team hosted a virtual forum for SIO Contributors to share information about sea-ice forecast methods, discuss related challenges, and identify activities and products that could advance forecasting skill. Participation was by invitation only and limited to individuals who recently submitted forecasts to the SIO. Meeting Products are under development and will be announced via the SIPN mailing list.
For questions, please contact Betsy Turner-Bogren, ARCUS (betsy [at] arcus.org).
2020 Sea Ice Outlook Interim Post-Season Report is Now Available Online
The 2020 Sea Ice Outlook Interim Post-Season Report is now available. The September monthly averaged sea ice extent at the end of the 2020 summer melt season was 3.92 million square kilometers. This is the second lowest in the satellite record that began in 1979.
This interim report is intended as a quick postseason update that summarizes how the outlooks did in comparison to the observed September monthly mean extent. A full post-season report, to be published in February 2021, will include an in-depth analysis of factors impacting sea ice this past summer, further discussion about the outlooks, comments on regional observation, predicted spatial fields, Antarctic contributions, and a summary from the Sea Ice Drift Forecast Experiment (SIDFEx).
SIPN Data Portal
The SIPN Data Portal, a contribution to SIPN2 and the Sea Ice Outlook, displays analysis of sea ice forecasts and compares them with observations.
Sea Ice Data at NSIDC
Through the National Snow and Ice Data Center (NSIDC), SIPN manages a comprehensive list of datasets useful for sea ice prediction.
