Maybe this paper has a serious background but this what the Ig committee really wants – making people laugh, and then think “Methane Emissions from the Munich Oktoberfest” in Atmospheric Chemistry and Physics.
This study presents the first investigation of the methane (CH4) emissions of a big festival. In 2018 we measured the CH4 emissions of Munich Oktoberfest, the world’s largest folk festival, using in-situ measurements combined with a Gaussian plume dispersion model. Oktoberfest is a potential source for CH4 as a high amount of natural gas for cooking and heating is used.
I believe this is a better proposal for the Ig Nobel Prize than my own Lancet letter about the Octoberfest.
