Frost hollow monitoring with our air temperature and humidity LoRaWAN sensors, an initiative by Stephan Vogt, monitors frost hollows in Switzerland. In this season he started to use Decentlab's air temperature and relative humidity with radiation shield (LoRaWAN) and the Data Access platform to monitor Hintergräppelen, a promising site to reach lowest temperatures in Switzerland.

On Tuesday morning we recorded a new minimum of this season with -21.89 °C. We are looking forward for a really cold winter.
