The CryosphereThe cryosphere collectively describes elements of the Earth System containing water in its frozen state. It includes solid precipitation, snow cover, sea ice, lake and river ice, glaciers, ice caps, ice sheets, permafrost, and seasonally frozen ground. The cryosphere exists at all latitudes and in about one hundred countries.

Frozen rain, 2008
Correlation between Arctic sea ice and Siberia high
Shrinking sea ice leads to more frequent extreme events in winter/spring in China

Informal Meeting of Asian GCW/CryoNet, decided a formal meeting that will be held in Beijing, Sep.17-19, 2013
![Page 26: Atmospheric and cryospheric related services on the Third Pole region: requirements and gaps Xiao Cun-de ( State Key Lab of Cryospheric Sciences, CAS;](https://reader036.fdocuments.us/reader036/viewer/2022062515/56649ccc5503460f94996b16/html5/thumbnails/26.jpg)
Regional CryoNet Workshop in Asia• The success of GCW and CryoNet depends on engagement of WMO members and
national agencies engaged in observation, monitoring, modelling and assessment of the cryosphere locally, regionally and globally - in China, the co-operation of CMA and CAS is essential
• In Asia – need the 3rd pole countries cooperating to maximize benefits
• CryoNet and GCW could offer a collective approach to improve: – environmental monitoring and modelling supporting policy and decision
making; – data management, including exchange, allowing data and information to be
shared locally (residents and government) and regionally; – implementation of standards for observation and exchange of cryospheric data
and information; – a collective long-term sustainable network to provide high quality data and
information for monitoring changes in the cryosphere and for validation and calibration ofmodels and satellite products
– Training in observation of the cryosphere

Regional CryoNet Workshop in Asia…2• Propose a workshop be held in central Asia, targeting efforts in the “Third Pole” region; it
is suggested the workshop on 17-19 September, Beijing)
• The workshop would aim to enhance regional capabilities for measurements of snow and
ice, and will expand collaboration between developing countries. Outcomes include:
– an inventory of available cryospheric information, products and services that
are currently available
– an assessment of regional needs for cryospheric information,
– the identification of potential collaborative regional contributions to GCW– the identification of observation sites in the region that can become part of the GCW
surface network (“CryoNet”)
