Calculated changes in total ablation for the period 7 July to 23 August (in m w.e.) after perturbations to input parameters: air temperature (T, ± 1 °C), relative humidity (RH, ± 10%), wind speed (WS, ± 0.3 and + 1.0 m s−1), and incoming (Sin, ± 50 W m−2) and reflected (Sref, ± 50 W m−2) shortwave radiation.
