A measurement campaign called "Methane-To-Go Poland" took place in October 2022 in Bielsko Biała. The main focus of the campaign was to measure methane emitted from the ventillation shafts of coal mines in Upper Silesia region. The data was gathered using a specially designed platform called "HELiPOD", on which sensors such as Li-7700, Picarro and 5-hole probe were installed. There was also a contribution from the Institute of Geophysics in the form of the Ultra Fast Thermometer. The platform was suspended below a helicopter, and plume penetrations on different heights and distances were performed in order to determine the flux of methane coming from the shaft.

During the seminar, I will sketch the measurement strategy, briefly summarize the collected data and present examples of preliminary results.
