  bibo_abstract:
  - We use meteorological data from two automatic weather stations (AWS) on Juncal
    Norte Glacier, central Chile, to investigate the glacier–climate interaction and
    to test ablation models of different complexity. The semi-arid Central Andes are
    characterized by dry summers, with precipitation close to zero, low relative humidity
    and intense solar radiation. We show that katabatic forcing is dominant both on
    the glacier tongue and in the fore field, and that low humidity and absence of
    clouds cause strong radiative cooling of the glacier surface. Surface albedo is
    basically constant for snow and ice, because of the scarcity of solid precipitation.
    The energy balance of the glacier is simulated for a 2-month period in austral
    summer using two models of different complexity, which differ in the inclusion
    of the heat conduction flux into the snowpack and in the parameterization of the
    incoming longwave radiation. Net shortwave radiation is the dominant component
    of the energy balance. The sensible heat flux is always positive, while both the
    net longwave radiation and latent heat flux are negative. Neglecting the subsurface
    heat flux and corresponding variations in surface temperature leads to an overestimation
    of ablation of 2% over a total of 3695 mm water equivalent (w.e.) at the end of
    the season. Correct modelling of incoming longwave radiation is crucial, and we
    suggest that parameterizations based on vapour pressure and air temperature should
    be used rather than on computed cloud amount. We also used an enhanced temperature-index
    model incorporating the shortwave radiation flux, which has two empirical parameters.
    We apply it both with values of parameters obtained for Alpine glaciers and recalibrated
    on Juncal Norte. The model recalibrated against the correct energy balance simulations
    performs very well. The model parameters respond to the meteorological conditions
    typical of this climatic setting.@eng
