In Tyrol, manual snow measurements are available from the hydrological year 1952/53. HS and SWE are sampled weekly by staff of the Tyrolean Hydrological Service in the close proximity of meteorological stations. These ‘station data’ are the basis for a regional-scale application accounting for an area of more than 12,000 km² (Figure 1). For measuring SWE, snow pits are dug to ensure that no snow is lost when the core is extracted from the pack. Additionally, data from a snow pillow at Kühtai (1,930 m a.s.l.) are used (Kirnbauer & Blöschl 1990) to densify the data pool at higher elevations. For consistency with the other station data, only one measured pair of HS and SWE from the snow pillow per week (randomly picked) in the period 1993–2010 is added to the calibration dataset. Overall, data from 35 stations were compiled for the period of 1952 to 2010. The mean observation length is 33 years and the data cover mainly the months from November to May. The stations are located at elevations between 528 and 2,036 m a.s.l., covering approximately 60% of the area of the province of Tyrol (Figure 1). Following Jonas et al. (2009), quality checks were carried out using ρ computed from HS and SWE, with data rejected where the computed ρ was outside the range of 50–600 kg m⁻³. Table 1 provides information about the snow data, the providers and the application of the data for calibration or validation.
