Four years of daily stable water isotope data in stream water and precipitation from three Swiss catchments.

ABSTRACT: Time series of the natural isotopic composition (²H, ¹⁸O) of precipitation and streamwater can provide important insights into ecohydrological phenomena at the catchment scale. However, multi-year, high-frequency isotope datasets are generally scarce, limiting our ability to study highly dynamic short-term ecohydrological processes. Here we present four years of daily isotope measurements in streamwater and precipitation at the Alp catchment (area 47 km²) in Central Switzerland and two of its tributaries (0.7 km² and 1.6 km²). This data set reveals short-term responses of streamflow isotopes to precipitation events, which otherwise remain obscured when isotopes are sampled weekly or monthly. The observations span the period June 2015 t
