Sea Ice Outlook: 2022 Post-Season Report
The 2022 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 discussions of the 2022 observed Arctic sea-ice, atmospheric, and ocean heat conditions during the sea-ice retreat season; a review of the 2022 contributed forecasts for the pan-Arctic sea-ice extent and extent anomalies, pan-Arctic sea-ice probability, and sea-ice extent forecasts for Alaska regional seas and the Antarctic; a summary from the 2022 Sea Ice Drift Forecast Experiment (SIDFEx); and brief discussion of next steps for the SIO and SIPN project.
Sea Ice Outlook September Report
The 2022 September 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 September SIO Report, 22 contributions were received that included pan-Arctic predictions. Of those contributions, seven included predictions for the Alaska region, seven included predictions for pan-Antarctic, and 10 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 conditions.
The median September Outlook value for September 2022 pan-Arctic sea-ice extent is 4.90 million square kilometers, which is higher than that from August (4.83 million square kilometers), July (4.64 million square kilometers), and June (4.57 million square kilometers).

2021 Sea Ice Outlook Post-Season Report
The 2021 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 a review of the 2021 SIO contributions and sea-ice extent anomalies, discussions and analysis of observed Arctic conditions during the sea-ice retreat season, a review of Antarctic conditions and contributions, discussions of SIO forecast methods and skill relative to control forecasts, information about new data products for sea-ice forecasting, and a summary from the Sea Ice Drift Forecast Experiment (SIDFEx).
SIPN2 and SIO in the News!
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.

SIPN2 Presentation to AGU 2021
During the 2021 American Geophysical Union Fall Meetings in New Orleans, Louisiana; Uma Bhatt, SIPN2 Lead Project Principal Investigator, presented a talk entitled "A Community of Practice Approach to Improving and Communicating Seasonal Sea-Ice Forecasts." Her presentation was developed with input from, and on behalf of, the SIPN2 Project Team. A PDF of her five-minute presentation slides is available here.
