[2017-06-13] WMO Executive Council approves 120 stations. On 15 May 2017 the WMO Executive Council (EC-69) approved 77 CryoNet stations and 43 contributing stations for the GCW surface observing network. See them at http://globalcryospherewatch.org/cryonet/sites.php.
[2017-05-12] WMO Gets Observer Status in Arctic Council, GCW Mentioned. The World Meteorological Organization (WMO) has been granted observer status at the Arctic Council, the leading intergovernmental forum promoting cooperation, coordination and interaction among the Arctic States and communities, particularly on issues of sustainable development and environmental protection in the Arctic. The 10th Arctic Council ministerial meeting, which took place in Fairbanks, Alaska on 12 May, admitted WMO and six other observers. The ministerial declaration recognized the “need to increase cooperation in meteorological, oceanographic and terrestrial observations, research and services, and the need for well-maintained and sustained observation networks and continuous monitoring of the Arctic, such as the World Meteorological Organization’s Global Cryosphere Watch Program.”
[2017-05-12] New assessments available for 2016 snow and permafrost. 2016 assessments are available for snow and permafrost. Thaw depth increases, more and deeper snow in some areas...http://globalcryospherewatch.org/assessments/.
[2017-05-01] New assessment page. A new assessment page has been added that provides an overview of recent changes across the cryosphere. A "stacked" time series plot shows changes in sea ice extent, snow cover, permafrost thaw depth, glacier mass balance, and ice sheet mass change. Look for it in the Assessment section of the Cryosphere Now.
[2017-04-12] Glacier mass balance continues to decline in 2016. 2016 will be the 37th consecutive year of negative glacial mass balances. Read more at <a href="http://globalcryospherewatch.org/assessments/glaciers/2016/">in the assessments</a>.
[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). Read more in the sea ice assessment at http://globalcryospherewatch.org/assessments/seaice/2016/.
[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 https://erecruit.wmo.int/public/ (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.
