Abstract

The resonant and non-resonant photoacoustic (PA) detection of atmospheric trace gases is discussed with special respect to field measurements. Continuous in-situ methane measurements in a cow shed by a non-resonant PA detector applying an HeNe laser are reported, which allow the model based determination of the methane production rate of cows.
