The measurement and modeling of Biogenic Volatile Organic Compounds (BVOC) are essential for understanding regional and global atmospheric chemistry, carbon cycles, and climate. Controlling anthropogenic emissions would reduce both ASOA and BSOA. The model simulations indicate that the contribution of biogenic VOC emissions to ozone formation is lower in June (9-11%) and August (6-9%) than in July (17-20%). Boreal peatlands have significant emissions of non-methane biogenic volatile organic compounds (BVOCs). This overview compiles the actual knowledge of the biogenic emissions of some volatile organic compounds (VOCs), i.e., isoprene, terpenes, alkanes, alkenes, alcohols, esters, carbonyls, and acids. Biogenic emissions were estimated at 23.54 Tg/yr, with a peak in the summer and decreasing from southern to northern China. The changes in ecosystem BVOC emission are evaluated under normal precipitation conditions, then throughout a controlled 2-month drought period, and finally through a re-wet period where rain was re-introduced to the rainforest. Monoterpenes are among the most frequently studied biogenic volatile organic compound (VOC) emissions from foliage, because they contribute a large part to total global hydrocarbon emissions, and are very reactive in the atmosphere (Fehsenfeld et al., 1992; Guenther et al., 1995).
