  • Worldwide glacier mass changes are considered to represent natural key variables within global climate-related monitoring programmes, especially with respect to strategies concerning early detection of enhanced greenhouse effects on climate
  • Effective sample size for glacier mass balance
  • The A. aims to determine the effective sample size of 2 glaciers by analysis of the spatial correlation between point mass balance measurements. Correlograms from multiple time series of point mass balance, measured on White Glacier (Axel Heiberg
  • Island, Canada) and Abramov Glacier (Alai Range, Kirgizia), show that the correlation decreases with the difference in elevation between the points. A principal component analysis confirms that the effective sample size is very small.
  • Effect of uncertainties in measured variables on the calculated mass balance of Storglaciären
  • Detailed mass balance measurements have been carried out on Storglaciären since 1945, adhering to a fixed system of measurements since the 1960s. Using a geographical information system approach, the effect of parameters such as density conversion
  • . Storglaciären is also used as a reference for all other glaciers in the programme. In general, Swedish glaciers are still responding to the major climatic warming around 1910-1920 by retreat, and the effect of very long response times. However, measured volume
  • regression equations were examined. The results point to dominant effect of the gradient of mass balance with altitude of alpine glaciers compared to transverse variations. The number of mass balance measurements required appears to be scale invariant
