TLDR
It is indicated that forest floor plays a substantial role in the boreal forest total VOC emissions, and the VOC fluxes correlated positively with temperature and light, while relative humidity correlated negatively.Abstract:
Background and Aims
Volatile organic compound (VOC) emissions from biogenic sources are important contributors to chemical reactions in the air. Soil/forest floor VOCs contribute significantly to the ecosystem scale emissions, however, these emissions and their temporal and spatial variations are poorly characterised. The below-canopy VOC emissions have been measured mainly in campaigns; continuous measurements over the whole growing season are rare.read more

Biogenic volatile emissions from the soil
Josep Peñuelas,Dolores Asensio,Dorothea Tholl,Katrin Wenke,Maaria Rosenkranz,Birgit Piechulla,Jörg-Peter Schnitzler +6 more
TL;DR: This review summarizes the scarce available data on the exchange of VOCs between soil and atmosphere and the features of the soil and particle structure allowing diffusion of volatiles in the soil, which is the prerequisite for biological VOC-based interactions.

Annual cycle of volatile organic compound exchange between a boreal pine forest and the atmosphere
TL;DR: In this article, the authors measured fluxes of several volatile organic compounds (VOCs) and oxygenated VOCs over a Scots-pine-dominated boreal forest semi-continuously between May 2010 and December 2013.

Contribution of understorey vegetation and soil processes to boreal forest isoprenoid exchange
TL;DR: In this article, a statistical model was constructed based on prevailing temperature, seasonality, trenching treatments, understory vegetation cover, above canopy photosynthetically active radiation (PAR), soil water content, and soil temperature to estimate isoprenoid fluxes.

Isoprene and monoterpene emission rate variability: Model evaluations and sensitivity analyses
TL;DR: In this paper, a simple exponential relationship between emission rate (E) and leaf temperature (T), E = Es [exp (β(T - Ts))], provides a good approximation for the temperature dependence of monoterpene emission.
