Context and objectives
Isoprenoids represent an important class of Biogenic Volatile Organic Compounds (BVOCs). Among plant BVOCs, isoprenoids form the most abundant class, with isoprene representing about half of the total BVOCs emitted globally. The presence of BVOCs – and in particular of isoprene – alters the cycle NO–NO2–O3 responsible for O3 formation & degradation leading to the formation of other secondary pollutants such as peroxyacyl nitrates (PAN’s) and particulate matter.
In the HYPI project we linked isoprene flux measurements at the leaf and canopy levels to hyperspectral vegetation indices. We aimed to demonstrate whether hyperspectral vegetation indices offer the possibility for an improved estimation of the spatial and temporal variability of isoprene emissions of ecosystems.
