Quantification of methane emissions from hotspots and during COVID-19 using a global atmospheric inversion [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Concentrations of atmospheric methane (CH4), the second most important greenhouse gas, continue to grow. In recent years this growth rate has increased further (2020: +15.6 ppb), the cause of which remains largely unknown.
