Abstract. Glacier-wide mass balance has been measured for more than sixty years and is widely used as an indicator of climate change to assess the glacier contribution runoff sea level rise. Until recently, comprehensive uncertainty assessments have rarely carried out data often applied using rough error estimation or without consideration errors. In this study, we propose a framework reanalysing series that includes conceptual statistical toolsets assessment random systematic errors, well...
ABSTRACT Glacier surface mass-balance measurements on Greenland started more than a century ago, but no compilation exists of the observations from ablation area ice sheet and local glaciers. Such data could be used in evaluation modelled mass balance, or to document changes glacier melt independently model output. Here, we present comprehensive database The spans 123 1892 2015, contains total ~3000 46 sites, is openly accessible through PROMICE web portal ( http://www.promice.dk ). For each...
Greenland’s peripheral glaciers and ice caps are particularly sensitive to a warming climate often respond more rapidly than the Greenland Ice Sheet. These smaller bodies also play vital role in local ecosystems. End-of-winter distribution of snow cover is key driver glacier mass balance, but predicting accumulation complex terrain challenging due interplay topography wind that influences snowfall deposition re-distribution. Accurate balance estimates must therefore rely on in-situ...
Measurements of the glacier mass balance are great climatic relevance, as glaciers serve reliable indicators climate change. They respond directly and sensitively to changes in long-term atmospheric conditions. virtually ‘live’ on same time scale To understand how a reacts prevailing its changes, measurements conducted some either annually or every six months. The winter measurement, usually performed early May when snow thickness is at greatest, assesses increase during...
Abstract Global warming is causing an apparent rapid retreat of many glaciers worldwide. In addition to mass-balance investigation, the determination and monitoring total glacial ice volume ice-thickness distribution are important parameters for understanding interactions between climate complex glacier system. Because spatially irregular sparse datasets, scaling often a challenging problem. This study focuses on two small (<2 km 2 ) temperate in Hohe Tauern (Eastern Alps) region central...
Abstract A detailed model of Alpine surface processes is used to simulate the amount preferential deposition as well redistribution snow due snowdrift for two alpine glaciers (Goldbergkees and Kleinfleißkees, Austrian Alps). The sequence snow-cover modelling consists simulation wind field with a mesoscale atmospheric model, three-dimensional finite-element drift module, an energy-balance module snowpack module. All modules exception wind-field are integrated within Alpine3D frame....
Abstract. Geometric effects induced by the underlying terrain slope or tilt errors of radiation sensors lead to an erroneous measurement snow ice albedo. Consequently, artificial diurnal albedo variations in order 1–20 % are observed. The present paper proposes a general method correct measurements cases where tilts both and slopes not accurately measured known. We demonstrate that atmospheric parameters for this correction model can either be taken from nearby well-maintained horizontally...
Abstract. The negative surface mass balance of glaciers and ice caps under a warming climate impacts local ecosystems, influencing the volume timing water flow in catchments while also contributing to global sea level rise. Peripheral distinct Greenland sheet respond faster change than main sheet. Accurate assessment depends on situ observations near-surface ablation, but very few ablation are freely available for Greenland's peripheral glaciers. transect three automated weather stations A....
Abstract. Greenland's peripheral glaciers are losing mass at an accelerated rate and contributing significantly to sea level rise, but only a few direct observations available. In this study, we use the unique combination of high-resolution remote sensing data balance quantify contribution singular avalanche event Freya Glacier (74.38° N, 20.82° W), small (5.5 km2, 2021) mountain glacier in Northeast Greenland. Elevation changes calculated from repeated photogrammetric surveys August 2013...

Glaciers are important and fast changing landscape elements in Hohe Tauern National Park (HTNP). In 1998, 10% of the HTNP area was covered with ice, less than half glaciated during Little Ice Age maximum. Glaciological monitoring includes mass balance measurements, glacier inventories, length change records flow velocity complemented by climatological, hydrological dendrochronological observations. All these data evidence climate history an outstanding way, comparable to few other sites world.
Abstract Humans currently perceive glaciers as icons of a pristine high mountain landscape. Glaciers attract millions visitors every year and add to building Alpine identity, but also provide ecosystem services. Using Austria’s largest glacier an example, we show that abundant water availability would allow artificial management conserve the under ongoing climate change, although costs in order €10 8 per exceed threefold related total visitor tourism revenues. While present theoretical...
Abstract. Global warming and glacier retreat are affecting the morphodynamics of proglacial rivers. In response to changing hydrology, altered hydraulics will significantly impact future glacifluvial erosion channel development. This study analyses a evolution process at foreland Austria’s biggest Pasterze, by predicted runoff until 2050 based on glacio-hydrological model. A high-resolution digital elevation model was created an unmanned aerial vehicle, sediment sampled, one-dimensional...
Little is known about the evolution and dynamics of icebergs in alpine lakes. We analyzed movement ablation patterns at an ice-contact lake Pasterze Glacier, Austria, using time-lapse images. Iceberg was quantified for two timescales related to meteorological as well glacier data from adjacent tongue. On a multiyear scale, one iceberg (IB1) monitored during twenty-five-month period. single-day paths eighty-four were tracked over 16 hours. Results IB1 revealed average 72 mm d−1 June September...
Abstract. The diurnal albedo variation of glaciers on clear sky days can be relatively high due to geometric effects induced by tilt errors. In the present paper, these errors measurements are corrected in cases where tilts both, sensors and slopes not accurately measured. For this method correction, a nearby reference measurement with horizontally levelled sensor is needed determine atmospheric parameters. Based that model developed fitted measured data directions slopes, which vary daily...
