CryoNet objectives

CryoNet will link with 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.

Initial CryoNet stations

www.globalcryospherewatch.org

CryoNet sites must meet a minimum set of requirements:

1. The site location is chosen such that, for the variables measured, it is spatially/temporally representative for measuring one or several components of the cryosphere.

2. CryoNet sites have to be active and perform sustained

observations according to CryoNet agreed practices.

3. Technical personnel are trained in the operation of the equipment at the site.

4. For reference and integrated sites, there is an intent by the responsible agencies to long-term observations of at least one of the CryoNet variables.

5. The relevant CryoNet observations are of documented quality. The measurements are made and quality controlled according to CryoNet agreed practices.

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 documented quality.

7. The data and metadata including changes in instrumentation, traceability, observation procedures are submitted to a data centre, which is interoperable with the GCW portal 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 kept up-to-date in the GCW station information database.

9. A station logbook for observations and activities that may affect observations is maintained and used in the data validation process.

10. User needs have been considered in the observation design process.
