o Questionaireso Cryosphere Station inventoryo Guide to GCW CryoNet (draft)o 2nd CryoNet WS (Dec. 2013, Beijing

Asia CryoNet Meeting, Bejing, China, Dec. 2013
Some key points:- Strong activity of China (e.g. book
describing their cryospheric monitoring activities)
- Idea of Regional Working Groups (need for potential other regional meetings)
- List of CryoNet candidate sites for Asia high mountains
- Strong interest for glacier monitoring and need for guideline/standard

CryoNet sites must meet a minimum set of requirements:
1. The site location is chosen such that, for the variables measured, it is regionally representative.2. There are adequate power, communication, and building facilities to sustain long-term observations with greater than 90% data capture (i.e. less than 10% missing data).3. Technical support personnel are trained in the operation of the equipment.4. For reference and integrated sites, there is a commitment by the responsible agency to long-term observations of at least one of the GCW variables.5. The relevant GCW observations are of known accuracy and precision. The measurements are made according to GCW standards. Quality monitoring and quality control are routinely performed.
CryoNet sites must meet a minimum set of requirements:
6. Associated standard meteorological in situ observations, when necessary for the accurate determination and interpretation of the GCW variables, are made with known accuracy and precision.7. The data and metadata are submitted to an international cryospheric data centre recognized by GCW no later than one year after the observation is made. Changes in metadata including instrumentation, traceability, observation procedures, are reported to the responsible data centre in a timely manner. Metadata are also provided to the WMO Operational Information Resource (WIR) and maintained regularly.8. The station characteristics and observational programme are updated in the GCW station information database on a regular basis.9. A station logbook for observations and activities that may affect observations is maintained and used in the data validation process.

CryoNet objectives
CryoNet will link different cryospheric observational networks to achieve its comprehensive potential through Extensive monitoring of the cryosphere through
harmonized measurements Providing cryospheric-data for improved process
understanding and modelling Providing calibration and validation data for satellite
data Linking cryospheric ground truth observations to
cryospheric models Training for cryospheric observations Standardized guidelines for cryospheric observations Long-term, sustainable observing and monitoring.
Feedback from the questionaires
Implementation of tiered networkHigh need for standards and guidelines
in cryospheric observations (many counts)

How making CryoNet successful
dependent on WMOBUThighly dependent on us (group of
researchers/promotors) through providing the theoretical background
relying on the strengths of WMO support (intercomparison studies, providing guidelines, networking, promotion, …) and not its weaknesses (WMO will not give any direct funding to a CryoNet station but can motivate its partners e.g. World Bank to do so via programs)
