Mass yields of secondary organic aerosols from the oxidation of alpha-pinene and real plant emissions by Kroll, Jesse, Hao, L. Q., Romakkaniemi, S., Yli-Pirilä, P., Joutsensaari, J., Kortelainen, A., Miettinen, P., Vaattovaara, P., Tiitta, P., Jaatinen, A., Kajos, M. K., Holopainen, J. K., Heijari, J., Rinne, J., Kulmala, M., Worsnop, D. R., Smith, J. N., Laaksonen, A.

“…This study presents smog chamber laboratory work, focusing on SOA formation via oxidation of the emissions of two dominant tree species from boreal forest area, Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies), by hydroxyl radical (OH) and ozone (O[subscript 3]). …”

The impact of bark beetle infestations on monoterpene emissions and secondary organic aerosol formation in western North America by Berg, A. R., Heald, Colette L., Huff Hartz, K. E., Hallar, A. Gannet, Meddens, A. J. H., Hicke, J. A., Lamarque, Jean-Francois, Tilmes, S.

“…Responses to beetle attack are shown to be substantially larger (up to a 3-fold localized increase in summertime SOA concentrations) in a scenario based on bark-beetle attack in spruce trees. Placed in the context of observations from the IMPROVE network, the changes in SOA concentrations due to beetle attack are in most cases small compared to the large annual and interannual variability in total organic aerosol which is driven by wildfire activity in western North America. …”
