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.
Call for SIPN2 Webinar Registration
The Sea Ice Prediction Network-Phase 2 (SIPN2) announces a call for registration for the upcoming webinar and discussion 2021 Sea Ice Outlook Post-Season Review. This 90-minute webinar will be held on Monday, 11 October from 9:00 am to 10:30 am (Alaska Daylight Time/ UTC−08:00). The webinar will provide a post-season review and discussion of the 2021 Sea Ice Outlook (SIO) and lessons learned. Registration is required and free of charge.
2021 September Sea Ice Outlook Report is Now Available Online
The 2021 September Sea Ice Outlook (SIO) report is now available online. The Sea Ice Outlook, managed by the Sea Ice Prediction Network–Phase 2 (SIPN2), 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.
This September Sea Ice Outlook (SIO) report—a new addition to the SIO season—was created in response to suggestions made during the 2021 January SIO Contributors Forum to solicit forecasts initialized in late August or early September for September mean Arctic sea-ice extent. The September SIO report provides a brief summary of the forecasts. The more comprehensive, full post-season report will be published in spring 2022.
For the pan-Arctic, the median September Outlook is 4.39 million square kilometers, equal to the August median and higher than the median of the June and July forecasts for 2021.
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).
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.
