Short summary
The paper demonstrates which different biological factors and physico-chemical processes are important regulators of soil isoprenoid emissions at different times of the year. With the obtained knowledge on soil VOC sources, it will be possible to add soil VOC production into air chemistry models and thus improve the understanding on climatic feedback mechanisms between secondary organic aerosol formation, clouds, and radiative forcing.
