  text: High elevation headwater catchments are complex hydrological systems that
    seasonally buffer water and release it in the form of snow and ice melt, modulating
    downstream runoff regimes and water availability. In High Mountain Asia (HMA),
    where a wide range of climates from semi-arid to monsoonal exist, the importance
    of the cryospheric contributions to the water budget varies with the amount and
    seasonal distribution of precipitation. Losses due to evapotranspiration and sublimation
    are to date largely unquantified components of the water budget in such catchments,
    although they can be comparable in magnitude to glacier melt contributions to
    streamflow. Here, we simulate the hydrology of three high elevation headwater
    catchments in distinct climates in HMA over 10 years using an ecohydrological
    model geared towards high-mountain areas including snow and glaciers, forced with
    reanalysis data. Our results show that evapotranspiration and sublimation together
    are most important at the semi-arid site, Kyzylsu, on the northernmost slopes
    of the Pamir mountain range. Here, the evaporative loss amounts to 28% of the
    water throughput, which we define as the total water added to, or removed from
    the water balance within a year. In comparison, evaporative losses are 19% at
    the Central Himalayan site Langtang and 13% at the wettest site, 24 K, on the
    Southeastern Tibetan Plateau. At the three sites, respectively, sublimation removes
    15%, 13% and 6% of snowfall, while evapotranspiration removes the equivalent of
    76%, 28% and 19% of rainfall. In absolute terms, and across a comparable elevation
    range, the highest ET flux is 413 mm yr−1 at 24 K, while the highest sublimation
    flux is 91 mm yr−1 at Kyzylsu. During warm and dry years, glacier melt was found
    to only partially compensate for the annual supply deficit.
