原始语种摘要: Biogenic volatile organic compounds (BVOCs) are substantial contributors toatmospheric chemistry and physics and demonstrate the close relationshipbetween biosphere and atmosphere. Their emission rates are highly sensitiveto meteorological and environmental changes with concomitant impacts onatmospheric chemistry. We have investigated seasonal isoprenoid andoxygenated VOC (oxVOC) fluxes from a Norway spruce ( Picea abies )tree in central Germany and explored the emission responses under variousatmospheric conditions. Emission rates were quantified by using dynamicbranch enclosure and proton-transfer-reaction mass spectrometry (PTR-MS)techniques. Additionally, ambient mixing ratios were derived throughapplication of a new box model treatment on the dynamic chamber measurements.These are...
