[2017-03-10] 1000+ terms added to the cryosphere glossary!. We"ve just added over 1000 entries to the cryosphere glossary! There are now 4141 entries from 26 sources; over 2200 are unique. http://globalcryospherewatch.org/reference/glossary.php.

[2016-11-14] A warm October results in record minimum Arctic sea ice extent. A very warm September and October across the Arctic Ocean, and particularly around the Beaufort and Chukchi Seas, resulted in a record minimum sea ice extent for October (but not September).

[2016-11-14] Waves of Snowballs/Iceballs. In late October, "snowballs" began washing up on the shore in the Gulf of Ob in Western Siberia. The balls occurred along 11 miles of beach. They ranged in size from a less than 10 cm to more than 80 cm in diameter. Lake Michigan, one of the Great Lakes in North America, had a similar event with large snow/ice balls in December 2015.

[2016-10-02] CryoNet and Best Practices Team meetings, Graz 2016. CryoNet and Best Practices Teams Meeting</b>, 20-24 September 2016, Graz, Austria. GCW held meetings of the CryoNet Team and the Best Practices Team 20-24 September 2016 in Graz, Austria. The meetings were hosted by the University of Graz. The CryoNet Team finalized the criteria by which surface stations will be added to the GCW network and evaluated many of the proposed sites. The Best Practices Team began the long process of compiling the GCW Guide, which will focus on recommended practices for measuring snow, ice, and permafrost properties, but will also include sections on data and metadata exchange, observational requirements, and integrated products. More information is available on the meeting page.

[2016-09-27] New trackers for sea ice temperature, albedo, and thickness. New experimental sea ice trackers have been added to the Cryosphere Now section of the GCW website. Sea ice temperature, albedo, and thickness trackers based on the AVHRR Polar Pathfinder-Extended (APP-x) dataset are available at http://globalcryospherewatch.org/state_of_cryo/seaice/. These are research products that are being evaluated.

[2016-04-22] PSTG SAR Data Compendium Released. A significant achievement of the WMO Polar Space Task Group (PSTG), a partner to GCW, is the synthetic aperture radar (SAR) Data Compendium from the SAR Coordination Working Group (SCWG). The SCWG coordinated the acquisition of several thousand images over a period of more than two decades, providing a rich and diverse dataset that can be used to examine changes in the polar regions.

[2016-02-17] GCW Project Office Project Manager vacancy. A GCW Office is being created in Geneva, and a Project Manager position is now open. See the announcement at  (vacancy 1956). It"s only open until March 4!

[2016-02-12] Successful 2nd Asia CryoNet Workshop in Salekhard. GCW held its Second Asia CryoNet meeting in Salekhard, Russia, western Siberia, 2-5 February 2016. CryoNet is the core of the GCW surface observing network. The workshop was organized by the Arctic and Antarctic Research Institute (AARI) of Roshydromet and the Administration of the Yamal-Nenets Autonomous Okrug (YaNAO). There were three days of plenary meetings in the YaNAO Administration building and one day of field training on Ob River north of Salekhard. The main objective of the workshop was to develop practical aspects of the implementation of CryoNet in Asia based on the decisions of the Seventeenth World Meteorological Congress (25 May – 12 June 2015). This includes, among others, identifying new stations/sites that could become CryoNet or contributing sites in both terrestrial and marine environments in Asia, reviewing existing observing practices for cryospheric observations and examining advances in measurement techniques, and discussing data policies. There was considerable media coverage of the event, including four of the workshop organizers discussing the cryosphere on a local TV show. Media coverage is listed on the GCW website at http://globalcryospherewatch.org/meetings/salekhard2016/media.html. The workshop was very productive, with more than 20 sites in the "Third Pole" (Himalaya) region and Siberia being proposed as new CryoNet sites. More information is on the meeting page

[2016-01-26] Snowzilla - The Blizzard of 2016. While snow storms happen all the time, this one paralyzed a few major U.S. cities. More information on the January 2016 blizzard is available under Interesting Events.

[2016-01-23] CryoNet Station and Site Type Definitions Refined. At the December 2015 CryoNet meeting in Boulder, Colorado, station and site type definitions were refined. The overall structure was simplified. For more information see the figure and visit the CryoNet station/site types web page.

[2016-01-23] New sea ice tracker from JAXA-NiPR. A new sea ice tracker from JAXA-NiPR (Japan) has been added to the Cryosphere Now. There is a tracker for each hemisphere.

[2016-01-23] The Glossary Keeps Growing. The glossary keeps growing. There are now 2900+ terms from 21 different sources. Check it out!

[2016-01-22] Steering Group and Multiple Team Meetings in Boulder. A joint meeting of the CryoNet Team and Portal and Website Teams was held at the University of Colorado, December 7-9 in Boulder Colorado. It was hosted by the National Snow and Ice Data Center (NSIDC). The GCW Steering Committee (GSG) met December 10-11, hosted by the Cooperative Institute for Research in Environmental Sciences (CIRES). The meetings established key steps for the next 1-2 years. More information is available on the meeting page.

[2015-12-17] The GCW Cryosphere Glossary is growing. Glossary update: Terms from six additional sources have been added to the GCW glossary. More will be added in the coming months. We now have over 2500 terms, about 1500 unique, compiled from 19 different sources! The Terminology Team is making a lot of progress. 

[2015-09-21] Second SnowPEx Workshop. The 2nd International Satellite Snow Products Intercomparison Workshop was held in Boulder, Colorado, 14-16 September 2015. The objective of the "SnowPEx" project is the intercomparison and validation of hemispheric and global satellite snow products for estimating temporal trends of the seasonal snow cover and assessing their accuracy. In the 1st International Satellite Snow Products Intercomparison Workshop, held at NOAA, Maryland, in July 2014, the community discussed and agreed on methods and protocols for the intercomparison of products and their validation using reference data sets from various environments and surface types around the world. The original snow product intercomparison project was started by the Snow Watch group of the World Meteorological Organization"s Global Cryosphere Watch (GCW) initiative in 2013. The SnowPEx project grew out of the first GCW Snow Watch workshop in Toronto, Ontario, Canada in January 2013. SnowPEx is funded by the European Space Agency (ESA). Additional information is available at http://calvalportal.ceos.org/projects/snowpex/isspi-2nd-workshop.
