Evaluation of GTN-G in 2014
 through GTN-G Advisory Board, under the lead of the International Association of
Cryospheric Sciences
 C. Rolstad Denby, L.M. Andreassen, A. Arendt, G. Cogley, V. Ryabinin
 (evaluation is a WDS-requirement)
 Evaluation of GTN-G and its operational bodies (WGMS, GLIMS, NSIDC) concerning
the monitoring of glaciers and ice caps:
 WGMS Klausur, 13 February 2014
 self-evaluation report (Q2)
 site visite (9-11 June 2014, Boulder)
 final evaluation report (Q4)

Evaluation of GTN-G in 2014 – outcome relevant to WGMS activities
 “The WGMS staff does an admirable job with data compilation, outreach, training
activities as well as scientific production.”
=>  (CATCOS, SMD4GC, MoU IRD/CRNS)
 “We do see strong potential for WGMS to act as a distributor of high level data derived
from remote sensing products, for example glacier-wide mass balances determined from
laser altimetry.”
=> Strengthen the remote sensing competence at WGMS (Glaciers_cci Option 5)
=> GLIMS/RGI issue to be solved at NSIDC and with NASA proposal
 “The Advisory Board supports the idea of merging the two products as a biennial
Fluctuations of Glaciers, which will free resources and offer the public a more timely
product.”
=> Global Glacier Change Bulletin (GGCB) series
 “the GTN-G web portal should be an early focus for improvements in publication of,
and access to, services that are already provided.”
=> WGMS MetaData Browser update postponed to 2015, priority on finalization of
