„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

GCOS Tiered Monitoring System
A multi-level, integrative strategy combining:
local process understanding with global coverage,
in-situ measurements with remote sensing, and
traditional observations with new technologies

Global Terrestrial Network for Glaciers: strategy
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)

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 noncommercial 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.
