  1. 1. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Alexandra Arnsteg; [2022]
    Nyckelord :BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Sammanfattning : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  3. 2. Estimation of the potential BVOC emissions by the different tree species in Malmö

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Larissa Lisa Gesa Scholz; [2019]
    Nyckelord :BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

    Sammanfattning : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. LÄS MER

  4. 3. Early season BVOC emission for young potted Norway spruce (Picea abies)

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Erica Jaakkola; [2019]
    Nyckelord :Physical Geography and Ecosystem analysis; BVOC; Norway spruce; PTR-TOFMS; photosynthesis; Earth and Environmental Sciences;

    Sammanfattning : Biogenic volatile organic compounds (BVOC) are emitted naturally from the biosphere to the atmosphere and are a part of the global carbon emissions. BVOCs are contributing to around 5-10% of the total net carbon exchange to the atmosphere. LÄS MER

  5. 4. The link between secondary organic aerosol and monoterpenes at a boreal forest site

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ying Zhou; [2017]
    Nyckelord :physical geography; ecosystem analysis; BVOC; SOA; Monoterpenes; temperature; relative humidity; wind; Earth and Environmental Sciences;

    Sammanfattning : Secondary organic aerosol (SOA) plays a significant role in climate change by altering the global atmospheric radiation budget. Biogenic volatile organic compounds (BVOCs) are major sources for the formation of SOA. LÄS MER

  7. 5. Is there new particle formation in the marine boundary layer of the North Sea?

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Natalia Kelbus; [2014]
    Nyckelord :Geography; Physical Geography; aerosol particles; new particle formation; nucleation; particle size distribution; NanoMap; Science General; Earth and Environmental Sciences;

    Sammanfattning : The effect of aerosol particles on climate and the human health emphasizes the necessity to focus on the research about aerosol particles. Aerosol particles emitted due to anthropogenic activities increase the scattering and absorption of solar radiation in the atmosphere which leads to an increased cooling of the climate (direct effect).
