Factors influencing the temporal variability of atmospheric methane emissions from Upper Silesia coal mines: a case study from the CoMet mission

Data sets

Emissions of CH4 and CO2 over the Upper Silesian Coal Basin (Poland) and its vicinity (Version 4.01) M. Gałkowski, A. Fiehn, J. Swolkien, M. Stanisavljevic, P. Korben, M. Menoud, J. Necki, A. Roiger, T. Röckmann, C. Gerbig, and A. Fix https://doi.org/10.18160/3K6Z-4H73

Short summary

Determination of emissions from coal mines on a local scale requires instantaneous data. We analysed temporal emission data for ventilation shafts and factors influencing their variability. They were saturation of the seams with methane, the permeability of the rock mass, and coal output. The data for the verification should reflect the actual values of emissions from point sources. It is recommended to achieve this by using a standardised emission measurement system for all coal mines.
