The original article was published after the first measurement campaign in the Upper Silesian Coal Basin in July 2022 and is available at the Institute of Atmospheric Physics Deutsches Zentrum für Luft- und Raumfahrt (DLR-IPA) website. The second measurement campaign in the Upper Silesian Coal Basin, in which our PhD student from the Atmospheric Physics Department, Stanislaw Król, participated, took place between the 10 - 19 of October 2022.

Measurement campaigns were conducted from the airport in Bielsko-Biała. The flights took place mainly near the "Pniówek" mine and the "Andrzej" shaft. Measurements were taken up and down from the shafts (horizontal distance ~0.5 km - 5 km), and at multiple altitudes up to ~1-2 km, to map CH4 emissions. After takeoff, a HELiPOD platform was attached to the helicopter, which has a number of measuring devices on board, including two CH4 sensors: a Picarro and a Li-7700. The helicopter with the platform crosses the CH4 plume, allowing it to be measured in three dimensions.

Thanks to the efforts of Stanisław, a graduate student of the Akademia Górniczo-Hutnicza w Krakowie, specializing in the study of surface fluxes of methane in municipal landfills, our UFT 2.0 ultra-fast thermometer (UFT-2) from the IGF Fluid Dynamics Laboratory has been also installed on the HELiPOD platform. The UFT-2 is capable of measuring temperatures in clouds and plumes with a spatial resolution of a few centimetres.
