Sea Ice Prediction Network

The 2022 July Sea Ice Outlook (SIO) Report is now available online. The Sea Ice Outlook, managed by the Sea Ice Prediction Network–Phase 2 (SIPN2) Project Team, provides an open process for those interested in Arctic sea ice to share predictions and ideas. The monthly reports contain a variety of perspectives—from advanced numerical models to qualitative perspectives from citizen scientists. The Outlook is not an operational forecast.

For the 2022 July report, 30 contributions were received that included pan-Arctic predictions. Of those contributions, eight included predictions for the Alaska region, nine included predictions for pan-Antarctic, and 12 submitted September mean sea-ice extent anomalies. This report includes discussions of the contributed forecasts for the pan-Arctic, Alaska region, and pan-Antarctic; Arctic sea-ice extent anomalies; predictions from spatial fields; and current condition.

The median July Outlook value for September 2022 pan-Arctic sea-ice extent is 4.64 million square kilometers, which is slightly higher than the median cited in the June report of 4.57 million square kilometers.

News that "Scientists aim to improve sea ice predictions' accuracy, access" has been widely shared in the print and broadcast media. These stories are based on the December 2021 presentation by the SIPN2 Leadership Team,"A Community of Practice Approach to Improving and Communicating Seasonal Sea-Ice Forecasts" during the 2021 American Geophysical Union Fall Meetings.
