The sensor’s principle of measurement deals with the transit-time measurement of an ultrasonic pulse. The sensor transmits several energy-charged pulses to the snow cover and subsequently receives its reflected signals. Based upon the required transit time of the ultrasonic signals, the USH-8 sensor calculates the current snow depth. The processing time of the ultrasonic pulses here is enormously influenced by the air temperature. For this reason, the snow depth sensor also possesses integrated temperature compensation. This takes into account the influence of the air temperature on the processing time of the ultrasonic signals, in the calculation of the snow depth. The calculation takes place in the sensor, so that the output signal provides the already converted snow depth. USH-8 Specifications: Snow Depth Measurement Range of measurement: 0 to 8 m Minimum distance to the maximum expected snow depth: 1 m Accuracy: 0,1 % (FS) Resolution 1 mm Principle of measurement: Ultrasonic (Frequency 50 kHz; Angle of reflected beam 12°) Integrated Compensation of the Air Temperature Temperature sensor: Integrated air-temperature sensor in self-venting radiation shield Range of measurement: -35 to 60 °C Resolution: 0,1 °C Non-linearity: ? 0,15 % Interfaces Analogue: Snow depth measurement 0/4 - 20 mA signal (configurable) Resolution: 12 Bit Max. load: 300 ? Digital: Snow depth measurement; air temperature; quality flag RS 232; serial interface Protocol: Various ASCII formats This sensor garamtees: - precise measurement of snow-depth in extreme conditions - additional air-temperature detection feature to measure snow-depth over a wide temperature range - the powerful ultrasonic impulses emitted by this sensor deliver reliable readings even when there is a difficult reflection ratio, as is the case with fresh snow.

An automatic weather station (AWS) is defined as a “meteorological station at which observations are made and transmitted automatically” (WMO, 1992a). In particular, in the framework of the SHARE project for all parameters, the data has been visually checked, looking for extremely and unusual low/high values and/or periods with constant values.
