Quantifying anthropogenic methane emissions and their uncertainties using very high spatial and spectral resolution satellite and airborne data

Kurzfassung

Methane is one of the most powerful greenhouse gases that has contributed to about a third of the 2010-2019 global warming relative to the pre-industrial times in 1850-1900. The Upper Silesian Coal Basin in southern Poland is one of the strongest anthropogenic methane (CH4) emitters in Europe, with emissions ranging from 228 to 339 ktCH4yr-1. In that region, ventilation shafts and drainage stations used in coal mines are the main sources of CH4 emissions, of which the mass flows and their sources of uncertainties can be assessed using an adapted version of the Integrated Mass Enhancement (IME) method.
