The aim of the group is to quantify and understand the emission of hydrocarbon compounds from vegetation. Especially, we aim at understanding the terpenoid emission from boreal ecosystems. The methods used include emission chamber techniques as well as micrometeorological flux measurements, such as disjunct eddy covariance and gradient technique.

An example of ecosystem scale monoterpene fluxes measured by the disjuct eddy covariance method (black dots) and two different emission modeling algorithms (blue and red lines). The algorithm shown as red line is based on recent isotope labeling study (Ghirardo et al., 2010, Plant, Cell & Environment, 33, 781-792. doi: 10.1111/j.1365-3040.2009.02104.x).
