Sea Ice Outlook: 2014 August Report
OVERVIEW
Thank you to the groups that contributed to the August 2014 Outlook. We received 23 pan-Arctic contributions. Of the 23 contributions, some are unchanged from July. The median Outlook value for September extent is 5.0 million square kilometers with a quartile range from 4.58 to 5.22 million square kilometers. The overall range is between 4.0 and 5.6 million square kilometers. The median value for August is increased from the June and July values of 4.7 and 4.8 million square kilometers, respectively. This increase reflects the relatively slower decline in ice extent through August
Sea Ice Outlook: 2014 July Report
EXECUTIVE SUMMARY
Thank you to the groups that contributed to the July 2014 Sea Ice Outlook; we received 28 pan-Arctic contributions and always appreciate the diversity of contributions.
The July Outlook report was developed by Walt Meier, NASA Goddard Space Flight Center, and the rest of the SIPN leadership team, with a section analyzing the model contributions by François Massonnet, Université Catholique de Louvain.
The median Outlook value for September 2014 sea ice extent is 4.8 million square kilometers with quartiles of 4.4 and 5.0 million square kilometers. Thus, the median

Full Outlook Report
Overview
Thank you to the groups that contributed to the 2014 season, 28 pan-Arctic contributions (plus one additional regional) is a record for the Sea Ice Outlook (SIO)! We appreciate the diversity of contributions. The median Outlook value for September 2014 sea ice extent is 4.7 million square kilometers with quartiles of 4.2 and 5.1 million square kilometers (See Figure 1). Thus we have a large distribution of Outlooks, which is not surprising given the different observed values from 2012 and 2013. The overall range is also large at 3.2 to 6.3 million
Thank you to the groups that contributed to the 2014 June report; 28 pan-Arctic contributions (plus one additional regional) is a record for the Sea Ice Outlook! We also welcome several new groups this year.
This June Outlook report was developed by lead authors, Walt Meier (NASA) and Jim Overland (NOAA), with contributions from the rest of the SIPN leadership team, and with a new section this year analyzing the model contributions by François Massonnet, Université Catholique de Louvain.

Sea Ice Outlook: 2013 Post-Season Report
POST-SEASON REPORT
HIGHLIGHTS & TAKE-HOME POINTS
Loss of summer Arctic sea ice took a pause in 2013 with September 2013 having the 6th lowest extent since satellite observations began in 1979: 5.4 million square kilometers, based on National Snow and Ice Data Center (NSIDC) estimates. The seven lowest minimum ice extents have occurred in the last seven years, 2007-2013.
Sea Ice Outlook: 2013 July Report
Summary
We appreciate the continuing contributions to the July Outlook (using June data). We received 21 Pan-Arctic responses for the September 2013 Arctic mean sea ice extent with a median value of 4.0 million square kilometers and the quartile values are 3.8 and 4.6 million square kilometers (Figure 1). The range of estimates was 3.2 to 5.9 million square kilometers. For comparison, the June 2013 median was 4.1 million square kilometers and the July median from 2012 was 4.6 million square kilometers.
Sea Ice Outlook: 2013 June Report
Summary
With 23 pan-arctic Outlook contributions, an increase over the last two years (thank you!), the June Sea Ice Outlook projects a September 2013 arctic sea extent (defined as the monthly average for September) median value of 4.1 million square kilometers, with quartiles of 3.8 and 4.4 million square kilometers (Figure 1).
