Biogenic volatile organic compounds (BVOCs) play a significant role in the interactions between the biosphere and the atmosphere, but their impact in northern latitudes is difficult to quantify due to a lack of measurements and modeling studies.
We present here the findings from our latest field campaigns in a mountain birch forest near Abisko (Northern Sweden), where we used Proton Transfer Reaction–Time of Flight–Mass Spectrometry (PTR–TOF–MS) and the Eddy Covariance technique to measure the ecosystem-scale fluxes of BVOCs during 3 growing seasons (2021, 2022, and 2023), to understand the diel cycle of these emissions. Furthermore, our study aims to observe and model the impact of herbivore insect defoliation on the gas exchange of the forest, caused by a caterpillar outbreak during our 2023 campaign.
