The Federal Department of Environment, Transport, Energy and Communications (DETEC) deals with infrastructure as well as with the environment. For this reason the focus is on the climate and weather forecasts. Meteomatics is an expert in the field of meteorology and is concerned with weather forecasting and the improvement of forecasts every day. In this context, Meteomatics developed a weather drone, the Meteodrone. As a flying weather station the Meteodrone collects data from the planetary boundary layer to close this gap. To show how it is possible to record extremely precise information on temperature, humidity and wind in the lower atmosphereMeteomatics was invited to the DETEC`s Open Day on June the 22nd.
