Mass balance of three Svalbard glaciers reconstructed back to 1948
A simple model using upper-air meteorological variables in the NCEP-NCAR Reanalysis database is used to model seasonal components of mass balance of three glaciers in Svalbard. The model was originally developed for glaciers in North America, and has been applied to glaciers in Norway, Sweden and Iceland. Over the period for which mass balance data are available for the three Svalbard glaciers,...
متن کاملAdjustment of regional climate model output for modeling the climatic mass balance of all glaciers on Svalbard
Large-scale modeling of glacier mass balance relies often on the output from regional climate models (RCMs). However, the limited accuracy and spatial resolution of RCM output pose limitations on mass balance simulations at subregional or local scales. Moreover, RCM output is still rarely available over larger regions or for longer time periods. This study evaluates the extent to which it is po...

متن کاملEstimating the long-term calving flux of Kronebreen, Svalbard, from geodetic elevation changes and mass-balance modelling
This study independently quantifies geodetic elevation change and models surface mass balance to solve the continuity equation. The approach is tested on two dynamically different glaciers, Kongsvegen and Kronebreen in northwest Svalbard, through two time epochs, 1966–1990/95 (I) and 1990/95–2007 (II). On Kongsvegen, a dynamically inactive glacier, the residual term represents an error associat...
متن کاملPhotogrammetric methods applied to Svalbard glaciers: accuracies and challenges
Use of digital images is expanding as a tool for glacier monitoring, and smallformat time-lapse cameras are increasingly being used for glacier monitoring of fast-flowing glaciers. Stereoscopic imagery is preferable since it yields direct displacement results but stereo photogrammetry has more requirements regarding geometry in set-up and control points, as well as the additional cost of anothe...
