abstract = {Methane is the second most important greenhouse gas in
terms of anthropogenic radiative forcing. Since
pre-industrial times, the globally averaged dry mole
fraction of methane in the atmosphere has increased
considerably. Emissions from coal mining are one of the
primary anthropogenic methane sources. However, our
knowledge about different sources and sinks of methane is
still subject to great uncertainties. Comprehensive
measurement campaigns and reliable chemistry–climate
models, are required to fully understand the global methane
budget and to further develop future climate mitigation
strategies. The CoMet 1.0 campaign (May to June 2018)
combined airborne in situ, as well as passive and active
remote sensing measurements to quantify the emissions from
coal mining in the Upper Silesian Coal Basin (USCB, Poland).
Roughly 502 kt of methane is emitted from the ventilation
shafts per year. In order to help with the flight planning
during the campaigns, we performed 6 d forecasts using the
online coupled, three-time nested global and regional
chemistry–climate model MECO(n). We applied three-nested
COSMO/MESSy instances going down to a spatial resolution of
2.8 km over the USCB. The nested global–regional model
system allows for the separation of local emission
contributions from fluctuations in the background methane.
Here, we introduce the forecast set-up and assess the impact
of the model's spatial resolution on the simulation of
methane plumes from the ventilation shafts. Uncertainties in
simulated methane mixing ratios are estimated by comparing
different airborne measurements to the simulations. Results
show that MECO(3) is able to simulate the observed methane
plumes and the large-scale patterns (including vertically
integrated values) reasonably well. Furthermore, we obtain
reasonable forecast results up to forecast day four.},
