The main meteorological station at the Széchenyi István Geophysical Observatory equipped mostly with Campbell Scientific meteorological instruments has undergone a major change in recent years. Data download from the data logger has been automated by a mini-PC, new instruments have been added (ceilometer, visibility and present weather sensor, barometer) and the station has been moved to a new location. Now it better complements the atmospheric measurements in the observatory, for example by facilitating the determination of the so-called fair-weather conditions for the evaluation of atmospheric potential gradient measurements. Additionally, a cooperation with the Hungarian Meteorological Service (HMS) has been established, in the framework of which meteorological data are transmitted from the observatory to the HMS. Plots of the station data, updated every 10 minutes, are available on the observatory’s website.
