|Kopisty Observatory is the oldest working mast station in the Czech Republic. It is equipped with an 80 m high mast for measuring vertical profiles of wind, temperature and humidity. Measurements are made on four floors at heights of 20, 40, 60 and 80 metres. In 2014, thanks to the CzechGlobe project, the mast was equipped with ultrasonic anemometers that measure flow in both horizontal and vertical directions. In cooperation with the Institute of Thermomechanics of the CAS, the measurements are used, for example, to study turbulence in the atmospheric boundary layer.
