Air humidity and temperature play an important role in mete- orology. Highly accurate measurements of these climate pa- rameters form the basis of accurate forecasts and meaningful records.
To ensure precise measurements, the probe is always installed in a ra- diation shield. Condensation on the probe in early morning mist or in fog results in incorrect measurements due to delayed measurement when the weather conditions change due to sunlight or if the fog lifts. In this case, a ventilat- ed radiation shield does not provide any improvement, as it cannot prevent condensation on the sensor.
