The 2019 July Sea Ice Outlook (SIO) report is now available online. The Sea Ice Outlook, an effort managed by the Sea Ice Prediction Network–Phase 2 (SIPN2), 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.
For the 2019 July report, 39 contributions were received that included pan-Arctic predictions. Of those contributions 8 also included pan-Antarctic predictions, 10 included regional predictions for Alaskan waters, and 6 were for the Hudson Bay region.
For the pan-Arctic, the median July Outlook value for September 2019 sea-ice extent is 4.28 million square kilometers with quartiles of 4.0 to 4.6 million square kilometers. As of the publication of this report, total Arctic extent was tracking below levels recorded in 2012, the year that ended up with the lowest September extent on record.
The Sea Ice Outlook provides an open process for those interested in Arctic sea ice to share predictions and ideas; the Outlook is not an operational forecast.
