Abstract

Methane is a greenhouse gas with an increasing concentration in the atmosphere due to human activities. The availabe inventories of CHj emissions contain large uncertainties, especially on a small scale. In this paper high-resolution time series of methane measurements are analysed. It is found that methane concentrations measured in source areas show stronger temporal and spatial variation than background locations. Observations at background locations form the lower limit for observations in source areas. Meteorological conditions, e.g. wind direction and veloc
