Evaluation of a process-based model for biogenic isoprene emissions

Terrestrial vegetation plays a crucial role in the regulation of atmospheric composition and climate that goes beyond that of carbon dioxide and surface energy fluxes (Arheth et al., 2008). In particular biogenic volatile organic compounds (BVOCs) affect the lifetime of some greenhouse gases (e.g. methane, Monson & Holland, 2001), are precursors of others (e.g. ozone, Sanderson et al., 2003) and are a source of secondary organic aerosol (SOA) (Claeys et al., 2004).
