WGMS WORKSHOP ON MEASUREMENT AND UNCERTAINTY ASSESSMENT OF GLACIER MASS BALANCE

摘要

From 9-11 July 2012 the World Glacier Monitoring Service (WGMS), in collaboration with Stockholm University, organized a workshop on measurement and uncertainty assessment of glacier mass balance. The workshop built on the results and experience of earlier workshops in Tarfala in 1998 (Published in Geogr. Ann. A) and in Skeikampen, Norway, in 2008 (published in Ann. Glaciol.). It was held at the Stockholm University Tarfala Research Station in northern Sweden. The major aims of the workshop were to discuss methods and to identify and quantify related uncertainties of mass balance measurements from the ground, air and space, as well as to provide best practices for the homogenization, validation and recalibration of (long-term) observational series. In view of the increasing number of long-term mass-balance series and the fact that there are several glaciers where the geodetic and glaciological results largely diverge, there is a strong need to address the questions raised. The meeting was attended by experts currently performing and (re-)analysing mass-balance measurements by means of glaciological and geodetic methods.
