GCW and Cryo. Net GCW observing system: Ø Satellites Ø GCW contributing stations Ø Cryo. Net network

Cryo. Net objectives Cryo. Net will link with different cryospheric observational networks to achieve its comprehensive potential through: Ø Extensive monitoring of the cryosphere through harmonized measurements Ø Providing cryospheric-data for improved process understanding and modelling Ø Providing calibration and validation data for satellite products Ø Linking cryospheric ground truth observations to cryospheric models Ø Training for cryospheric observations Ø Standardized guidelines for cryospheric observations Ø Long-term, sustainable observing and monitoring

Cryospheric surface observations have complex structure

Cryo. Net stations and sites

Minimum requirements for Cryo. Net stations 1. 2. 3. 4. 5. 6. 7. 8. Stations must be active. Observations are made and quality controlled according to Cryo. Net best practices. The responsible agencies are committed, to the extent reasonable, to sustaining long-term observations of at least one cryosphere component. There must be a commitment to continue measurements for a minimum of four (4) years. The station location is chosen such that cryospheric measurements are representative of the surrounding region, and such representativeness needs to be clearly described. User needs have been considered in the observation design process. Personnel must be trained in the operation and maintenance of the station. In situ ancillary meteorological observations as required in the Cryo. Net best practices are made with documented quality. The station characteristics and observational programme information are kept upto-date in the GCW station information database. Station metadata are also provided to the WIGOS Information Resource (WIR) and updated regularly. Make data freely available, whenever possible in (near-)real time
