Call for Sea Ice Outlook Contributions
Sea Ice Prediction Network (SIPN) team members announce the call for contributions for the 2023 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. Monthly reports will include a variety of contributions—from advanced numerical models to qualitative perspectives from citizen scientists—as well as brief related discussions. Plans for a brief Post-Season Report will be developed at the end of the retreat season. The 2023 SIO effort is supported with funds from NSF award #1331083.
All past contributors and new participants are encouraged to submit Outlooks for 2023. Please distribute this announcement to others who might be interested in participating in the SIO.
Submission Deadline: 6:00 p.m. (AKDT) Monday, 12 June 2023 (Firm)
SIPN Journal Article
We are excited to share a recent publication by Sea Ice Prediction Network-Phase 2 (SIPN2) team members on the forecast skill of the Sea Ice Outlook: Blanchard-Wrigglesworth, E., Bushuk, M., Massonnet, F., Hamilton, L. C., Bitz, C. M., Meier, W. N., & Bhatt, U. S. (2023). Forecast skill of the Arctic Sea Ice Outlook 2008–2022. Geophysical Research Letters.
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.
