- GCW Second Asia CryoNet Workshop, 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 info]

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). [More info]

- First GCW Snow Watch Workshop, 28-30 January 2013, Toronto, Canada. The meeting was hosted by Environment Canada. The purpose of this first workshop was to (1) determine the current state of snow data, products and information, particularly satellite products, (2) identify any critical issues that need to be addressed, (3) make recommendations on the initial content and structure of a GCW Snow Watch project, and (4) establish a GCW task team to oversee the development of a GCW Snow Watch. It is hoped that Snow Watch workshops will become an annual event. The workshop recommendations were to
- initiate a satellite snow products validation/intercomparison activity,
- initiate a PI self-assessment for snow products,
- initiate a global snow data rescue activity,
- develop "Snow Trackers" for SE and SWE at the Finnish Meteorological Institute,
- develop inventory of existing snow datasets,
- develop better linkages GCW products team,
- initiate activity to standardize snow-related nomenclature, and
- improve snow depth obs on GTS (zero value reporting, missing regions.
- First Cryonet Workshop, 20-22 November 2012, Vienna, Austria The meeting was hosted by the Zentralanstalt für Meteorologie und Geodynamik (ZAMG, the Austrian weather service). There were about 30 workshop participants representing observing sites in China, Japan, USA, Canada, Austria, Norway, Finland, Germany, Argentina, Russia, and Antarctica (France). Presentations were given on each of the observing sites, complemented by presentations on data assimilation (ECMWF), satellite observing systems, and WMO measurement standards. Three breakout groups were each given the task of creating a structure for CryoNet by defining different types of sites, basic measurements for each of the site types, requirements for inclusion in CryoNet. They were also asked to identify existing documents on snow and ice measurement standards and practices. The workshop was very productive overall, and a critical step in the deveopment of CryoNet and the implementation of GCW. Workshop recommendations and outcomes include:
- CryoNet should be a three-tier network of Baseline, Reference, and Integrated sites.
- Create an inventory of existing measurement standards and practices.
- Develop requirements for site inclusion in CryoNet.
- Develop a CryoNet Manual and a GCW Measurement Guide.
- Develop a cryosphere terminology
- A CryoNet Team was defined.
