Due to its high short-term global warming potential (GWP) compared carbon dioxide, methane (CH4) is a considerable agent of climate change. This research aimed at analyzing data on gathered the GAW (Global Atmosphere Watch) station Lamezia Terme (Calabria, Southern Italy) spanning seven years continuous measurements (2016-2022) and integrating results with key meteorological data. Compared previous studies detected mole fractions same station, daily-to-yearly patterns have become more prominent thanks analysis much larger set. Overall, yearly increase in general agreement by NOAA, though local peaks are present, an linked Covid-19 identified. Seasonal changes trends proved be fully cyclic, daily cycles being largely driven wind circulation synoptic features. Outbreak events been statistically evaluated depending their weekday occurrence test possible correlations anthropic activities. A cross between specific directions has also that sources may deemed responsible for highest fractions.
