R. Eisma et al., DETERMINATION OF EUROPEAN METHANE EMISSIONS, USING CONCENTRATION AND ISOTOPE MEASUREMENTS, Environmental monitoring and assessment, 31(1-2), 1994, pp. 197-202
The determination of methane emissions on a regional scale is needed i
n order to reduce some of the uncertainties in the global methane budg
et. Our measurements of the concentration and the Carbon-13 isotope co
mposition (deltaC-13) of atmospheric methane are, combined with trajec
tories, used to get insight in the type and size of the methane emissi
ons of a large area.
