Observations of Arctic Snow and Sea Ice Thickness from Satellite and Airborne Surveys

This webinar, organized by the Sea Ice Prediction Network Leadership Team, provided information on the current state and availability of snow and sea ice thickness data from NASA's Operation IceBridge airborne surveys and the European Space Agency's CryoSat-2 satellite mission. The accuracy and limitations of these operational data sets was also discussed to place the utility of the data in context for use in a variety of study areas.

Sea Ice Modeling: Characteristics and Processes Critical for the Radiation Budget

This webinar was organized by the Sea Ice Prediction Network Leadership Team. It provided an overview that included topics in sea ice modeling from the global climate modeling perspective and recent development within the Los Alamos Sea Ice Model CICE (aslo known as the Community Ice CodE) to more accurately represent sea ice characteristics and processes critical for the radiation budget of the ice pack.

Formed from frozen seawater rich in biological and chemical species, sea ice exists as a thin layer at the interface of the ocean and atmosphere, quite sensitive to small changes in temperature and radiative forcing. The high albedo of the ice pack is critical for the Earth's heat balance, and ice motion across the ocean's surface transports fresh water and salt. The basic components in a complete sea ice model must include both vertical thermodynamics and horizontal dynamics.

9 October 2014 Sea Ice Outlook: Post-Season Discussion

9 October 2014

This open webinar, hosted by the Sea Ice Prediction Network (SIPN), focused on post-season analysis and discussion of the 2014 Sea Ice Outlook (SIO). The SIO produces reports in June, July, and August that synthesize a variety of predictions and perspectives on the arctic sea ice minimum. The webinar provided a venue for discussion of the 2014 SIO, including processes that influenced sea ice melt this year and a review of the differing approaches to predicting the sea ice minimum extent.

Questions for Participants

In preparation for the webinar, participants we encouraged to think about the following questions:

  • How would you characterize the success of Sea Ice Outlook predictions this year, including relative strengths or weaknesses of different methodologies?
    [Note: On 7 October 2014 NSIDC announced the Arctic sea ice extent averaged for the month of September 2014 was 5.28 million square kilometers (2.04 million square miles), also the 6th lowest in the satellite record. More information is available here.]
  • What do you see as the main factors driving this year’s minimum extent?
  • If you were a SIO contributor, are there specific datasets or other information that would have been useful to have for your predictions?
  • What would you like to see changed (or kept the same) about the SIO?
  • What kind of post-season analyses or activities would you like to see?
  • Where do we go from here as a sea ice prediction community?

20 February 2014 Sea Ice Prediction Network Webinar

20 February 2014

This Sea Ice Prediction Network (SIPN) webinar was hosted by the Arctic Research Consortium of the U.S. (ARCUS). This webinar provided a brief summary of SIPN project goals and began discussions on how to improve sea ice predictions, specifically for the 2014 Sea Ice Outlook.

Guest Speakers include Dr. Julienne Stroeve of the National Snow & Ice Data Center in Boulder, Colorado, Dr. Cecilia Bitz of the Polar Science Center and Department of Atmospheric Sciences at the University of Washington, and post-doc Dr. Edward Blanchard-Wrigglesworth in the Department of Atmospheric Sciences at the University of Washington.
