  17. history ¦ organisation ¦ monitoring strategy ¦ website ¦ datasets „policy-related monitoring“ means that… …observations must be relevant feasable cost-effective …corresponding strategies must be future-oriented coherent …and the resulting products must be useful understandable

  18. GCOS Tiered Monitoring System history ¦ organisation ¦ monitoring strategy ¦ website ¦ datasets A multi-level, integrative strategy combining:local process understanding with global coverage, in-situ measurements with remote sensing, and traditional observations with new technologies

  19. Global Terrestrial Network for Glaciers: strategy history ¦ organisation ¦ monitoring strategy ¦ website ¦ datasets main goals of long-term observations: • process understanding • model validation • change detection • impact assessments Haeberli et al. (2000) change detection: • rate of change • acceleration trends • pre-industrial variability • change patterns integrated / tiered observing strategy Tier 1: multi-component obs. system across environmental gradients Tier 2:process understanding and model calibration => extensive energy & mass balance studies Tier 3:regional indicators => mass change (stakes&pits, photogrammetry, LIDAR) Tier 4:regional representativeness => cumulative length change; DEM differencing Tier 5:global coverage => inventories (remote sensing/geoinformatics)

  23. history ¦ organisation ¦ monitoring strategy ¦ website ¦ datasets GTN-G data policy • Endorsement of ICSU’s fundamental principal of full and open exchange of data and information for scientific and educational purposes. • One-year retention period is granted to allow all investigators and data contributors time to properly analyse, document, and publish their data and results before submitting them in standardized formats to GTN-G. • All data submitted to GTN-G are considered public domain for non-commercial use and are made digitally available at no costs. • The use of data and information from GTN-G requires acknowledgement to the respective GTN-G operational bodies (WGMS, NSIDC, GLIMS) and/or the original investigators and sponsoring agencies according to the available meta-information. • All GTN-G datasets come with citation recommendations and digital object identifiers.

  24. www.wgms.ch ¦ www.nsidc.org ¦ www.glims.org ¦ www.gtn-g.org 120 years of internationallycoordinated glaciermonitoring compilation and dissemination of standardized data about glacier distribution and changes GTN-G is today’s organisationalframework for the glacierdata centers and services
