TY - T1 - Emission measurements of biogenic volatile organic compounds in multiple scales SN - / UR - URN:ISBN:978-952-5822-60-1; http://hdl.handle.net/10138/36774 T3 - A1 - Haapanala, Sami A2 - PB - Helsingin yliopisto Y1 - 2012 LA - eng AB - Volatile organic compounds (VOCs) are reactive trace gases abundant in the atmosphere. As strongly reactive constituents they have many impacts on the atmospheric chemistry. To properly understand the processes involved in VOC cycles within the biosphere and atmosphere, we must have comprehensive knowledge on the biogenic and anthropogenic emissions and atmospheric concentrations. In this thesis, the emissions of VOCs were measured in many scales from various Fennoscandian ecosystems, utilizing ... VO - IS - SP - OP - KW - meteorologia N1 - PP - ER -
