    Moving averaging of the wind velocity and wind direction acc. to the WMO- recommendations: The wind data can be averaged moving over a time span of up to 10 minutes on a base of 100 millisecond values. This averaging is calculated according the recommendation of the WMO as the FIFO-method.

  • Page 11: Temperature And Humidity Measurement

    3.2 Temperature and humidity measurement: A built-in hygro-thermo sensor with an I C interface is used to measure temperature and humidity levels. The sensor's power consumption is so low that even when actively performing measurement, the increase in temperature through heat loss can hardly be measured. The hygro-thermo sensor is protected from the ingress of water by a miniature housing with a vapour-permeable membrane.

    moving towards or away from the Doppler radar module. The speed at which rain drops fall is roughly proportional to the square root of the drop diameter (Gunn and Kinzer 1949). The precise relationship between the speed at which rain falls and the diameter / volume of the rain drops can be used to calculate individual volumes and thus the rainfall intensity based on the frequency rate and the frequency of the Doppler frequencies.
