We need a new primary FrostByte editor

FrostbyteAs our current FrostByte editor, Erik Warming, have gained new responsibilities here at CliC, we need a new primary FrostByte editor.

About this volunteer work Erik wrote:

This is an interesting assignment. I am a geophysicist with focus on Greenland ice sheet and ice cores. Through this work I have gained an insight in lots of the other disciplines within polar research. Arctic flora, permafrost, the migration patterns of the arctic birds and Antarctica’s sea ice and glaciers, just to mention a few.

It is also refreshing to work with a media where you are allowed to play around and have some fun with the over wise serious science.

“Work” is maybe too big a word. More than two thirds of all the FrostBytes are already completed by the creator. The rest don’t have the skill/computer power and then I do the rest (see how-to video). When I have a ready FrostByte, I then upload it and post it on the CliC homepage. I will give my replacement a thorough guidance and stay as a secondary FrostByte editor.

Larry Hinzman, CliC SSG Member, Elected to IASC Executive Committee

CliC Scientific Steering Committee Member, Larry Hinzman, has been elected as a Vice-President of the International Arctic Science Committee (IASC). CliC has had a long and productive relationship with IASC and with Larry's new position, we hope this will continue to strengthen our partnership.

Statement from IASC:

At its annual meeting during the Arctic Science Summit Week 2014 in Helsinki on April 8, the IASC Council elected a new President and three Vice-Presidents. The new IASC President is Susan Barr, Norwegian Directorate for Cultural Heritage. Susan Barr has been working on the IASC Executive Committee as a Vice-President since 2010 and she is now taking over the Presidency from David Hik whose 4-year term came to an end. David Hik will, however, continue to work with the Executive Committee in his function as the Chair of the 3rd International Conference on Arctic Research Planning (ICARP III). IASC Council re-elected Vice-President Naja Mikkelsen, Geological Survey of Denmark and Greenland, for another 4 years. Larry Hinzman, International Arctic Research Center, Fairbanks AK, and Vladimir Pavlenko, Russian Academy of Sciences, were elected new Vice-Presidents. The Executive Committee is complemented by the fourth Vice-President Huigen Yang, Polar Research Institute of China, and the Executive Secretary Volker Rachold.

Understanding and Teaching about Ice Sheets and Sea Level Rise, a PEI Webinar

- Polar Educators, International (PEI) is a CliC Sponsored organization

Polar Educators, International (PEI), an international organization created to sustain and enhance the many successful education initiatives begun under the last International Polar Year (http://www.polareducator.org/) sponsored by CliC and the Arctic Research Consortium of the US, is pleased to announce the development of a new Master Class series targeting a dual audience: educators seeking cutting-edge professional development on the latest polar science discoveries and researchers interested in learning proven tactics for communicating scientific concepts in a clear and meaningful way.

We welcome your support in getting the word out to your communities and networks, and have attached a flyer advertising the first class, “Slip Sliding Away: Ice Sheets and Sea Level Rise,” held 7-23 May 2014, for that purpose.

Featuring leading researcher Dr. Richard Alley and polar educator, Ms. Nell Herrmann the class is being offered free to all participants.  Membership in PEI is required for participation in Master Class activities. Registration is due by 2 May 2014, with the initial web seminar taking place Wednesday, 7 May 2014 @ 8PM EDT/Thursday, 8 May 2014 @ 0000 GMT.

Further information on how to participate is available at:  http://www.polareducator.org/activities/master-class

1st International Satellite Snow Products Intercomparison workshop (ISSPI)

Monday, 21 July 2014 to Wednesday, 23 July 2014
College Park, Maryland, USA


The workshop is organised by the ESA SnowPEX Project in cooperation with NOAA / NASA, and supported by the WMO / Global Cryosphere Watch (GCW) and the WRCP / CliC.

Seasonal snow is a main element of the global water cycle and climate system. Due to the strong influence on the radiation and energy balance, changes in snow extent tend to amplify climate fluctuations. Terrestrial snow covers up to 50 million km2 of the Northern Hemisphere in winter, and is characterized by high spatial and temporal variability. Therefore satellite observations provide the only means for timely and complete observations of the global snow cover. The recently published 2013 IPCC Working Group 1 report identified seasonal snow as significantly decreasing during recent decades. The importance of producing better global scale snow cover data sets has been addressed in the WCRP-CliC Workshop on “WCRP Grand Challenges of the Cryosphere in a Changing Climate”, held in Tromsø, 16-18 Oct. 2013. Also in the WMO Global Cryosphere Watch Workshop in January 2013 the need of intercomparing snow products from various sensors and methods was identified. This is the first of two international workshops with the aim to bring together scientists and institutions working in seasonal snow pack monitoring in order to assess the quality of current satellite-based snow products derived from EO data and work out guidelines for improvement. Scientists are encouraged to submit abstracts for presentations and posters for the workshops.

Abstract submission and registration deadline is 15 May 2014


Tell us what your requirements are for Southern Ocean satellite data

What are your requirements for Southern Ocean satellite data? Are your data needs being met? Take this quick online survey!


This joint initiative of Southern Ocean Observing System (SOOS), Climate and the Cryosphere (CliC), and World Meteorological Organization Polar Space Task Group (WMO PSTG) aims to identify the satellite data requirements for the Southern Ocean (across all temporal/spatial scales) and to compile this information into a community report of Southern Ocean satellite data requirements.

This is a great opportunity to voice your needs, and feed information directly into the strategic planning for future missions. Provide feedback on current data streams, issues with data access, validation issues, gaps in data products, spatial and temporal coverage etc. This survey is open to all Southern Ocean data users, across all data types (air-sea ­flux, sea ice, biological, physical, etc)

Deadline 31 May 2014

If you have any questions please contact Louise Newman () or Jenny Baeseman ()

Call for Abstracts: Cryosphere in a Warming World

Registration and abstract submission is ongoing for the Climate Symposium, which will take place in Darmstadt, Germany on 13-17 October 2014.   
Of particular interest is the session entitled “Cryosphere in a Warming World” for which contributions are welcomed in areas related to satellite observations of the crysophere, the use of such observations in improving our understanding of processes and feedbacks involving the cryosphere, and future needs or opportunities to make use of existing or planned observations to allow better quantification of the changing cryosphere and the implications for adaptation and decision making. The session is chaired by Greg Flato (Environment Canada, CliC Co-Chair) and Vladimir Kattsov (Voeikov Main Geophysical Observatory, Lead author of the Cryosphere in a Changing Climate Grand Challenge White Paper).
We would like to highlight the following deadlines for registration and abstract submission which are fast approaching:
31 March 2014 – Deadline to submit applications for travel support
15 April 2014 – Deadline to submit abstracts (everyone)
15 May 2014 – Early registration deadline

Report Available from Northern Hemisphere Polar Jet Stream Linkages Workshop

Contributed by James E. Overland and Edward Hanna

The Northern Hemisphere polar jet stream and links with Arctic climate change IASC/CliC/IMO/NOAA Workshop was held on 13-15 November 2013 at the Icelandic Met Office in Reykjavik, Iceland. The workshop was successful with 33 scientists who have recently worked on jet stream and Arctic linkages issues. The workshop consisted of summary talks and extensive time for discussion during the sessions and during breaks and meals provided by IMO.  Iceland provided this group of meteorologists and oceanographers with some outstanding weather:  a major storm followed by snow. The agenda and list of participants are provided at the end.  We appreciated the major support of IASC and CliC, and the hospitality of our hosts at IMO.
