Zusammenfassung |
Fluxes of biogenic volatile organic compounds (VOC) and methane were
measured above a boreal fen. Vegetation on the fen is dominated by
Sphagnum mosses and sedges. A relaxed eddy accumulation (REA) system with dynamic
deadband was designed and constructed for the measurements. Methane,
C2-C6 hydrocarbons and some halogenated hydrocarbons were analysed
from the samples by gas chromatographs equipped with FID and ECD. A
significant flux of isoprene and methane was detected during the growing
seasons. Isoprene emission was found to follow the common isoprene emission
algorithm. Average standard emission potential of isoprene was 680 µg
m-2 h-1. Fluxes of other non-methane hydrocarbons were below
detection limit. |
