| Zusammenfassung |
| Glacier-wide mass balance has been measured for more than sixty years and is
widely used as an indicator of climate change and to assess the glacier
contribution to runoff and sea level rise. Until recently, comprehensive
uncertainty assessments have rarely been carried out and mass balance data
have often been applied using rough error estimation or without
consideration of errors. In this study, we propose a framework for
reanalysing glacier mass balance series that includes conceptual and statistical
toolsets for assessment of random and systematic errors, as well as for
validation and calibration (if necessary) of the glaciological with the
geodetic balance results. We demonstrate the usefulness and limitations of
the proposed scheme, drawing on an analysis that comprises over 50 recording
periods for a dozen glaciers, and we make recommendations to investigators
and users of glacier mass balance data. Reanalysing glacier mass balance
series needs to become a standard procedure for every monitoring programme
to improve data quality, including reliable uncertainty estimates. |
