Isoprene plays a significant role in tropospheric chemistry due to the large amount of emission and its high chemical reactivity. It is the major species of Biogenic Volatile Organic Compounds (BVOCs) emitted from terrestrial vegetation and accounts for half of global BVOC emission (Guenther et al., 2012). Isoprene is an important precursor of ozone and secondary organic aerosol (SOA) (Claeys et al., 2004;Sillman, 1999), so accurately estimating isoprene emission is required to understand the ozone and SOA relevant chemical and physical processes for improving air quality and managing their climatic impact.The emission of isoprene is affected by multiple environmental factors like light condition and temperature (
