  text: '[1] During the ablation period 2001 a glaciometeorological experiment was
    carried out on Haut Glacier d''Arolla, Switzerland. Five meteorological stations
    were installed on the glacier, and one permanent automatic weather station in
    the glacier foreland. The altitudes of the stations ranged between 2500 and 3000
    m a.s.l., and they were in operation from end of May to beginning of September
    2001. The spatial arrangement of the stations and temporal duration of the measurements
    generated a unique data set enabling the analysis of the spatial and temporal
    variability of the meteorological variables across an alpine glacier. All measurements
    were taken at a nominal height of 2 m, and hourly averages were derived for the
    analysis. The wind regime was dominated by the glacier wind (mean value 2.8 m
    s−1) but due to erosion by the synoptic gradient wind, occasionally the wind would
    blow up the valley. A slight decrease in mean 2 m air temperatures with altitude
    was found, however the 2 m air temperature gradient varied greatly and frequently
    changed its sign. Mean relative humidity was 71% and exhibited limited spatial
    variation. Mean incoming shortwave radiation and albedo both generally increased
    with elevation. The different components of shortwave radiation are quantified
    with a parameterization scheme. Resulting spatial variations are mainly due to
    horizon obstruction and reflections from surrounding slopes, i.e., topography.
    The effect of clouds accounts for a loss of 30% of the extraterrestrial flux.
    Albedos derived from a Landsat TM image of 30 July show remarkably constant values,
    in the range 0.49 to 0.50, across snow covered parts of the glacier, while albedo
    is highly spatially variable below the zone of continuous snow cover. These results
    are verified with ground measurements and compared with parameterized albedo.
    Mean longwave radiative fluxes decreased with elevation due to lower air temperatures
    and the effect of upper hemisphere slopes. It is shown through parameterization
    that this effect would even be more pronounced without the effect of clouds. Results
    are discussed with respect to a similar study which has been carried out on Pasterze
    Glacier (Austria). The presented algorithms for interpolating, parameterizing
    and simulating variables and parameters in alpine regions are integrated in the
    software package AMUNDSEN which is freely available to be adapted and further
    developed by the community.'
