Volatile Organic Compounds (VOCs) are key components in the atmospheric oxidative capacity. They play a key role in aerosol formation (secondary organic aerosol, SOA), atmospheric chemistry by the ozone formation, and cloud formation implying high sanitary and climatic impacts (Seinfeld and Pandis, 2016;Tripathi et al., 2022).Despite being considered to be a dominant source of biogenic VOCs (BVOCs) such as isoprene and monoterpenes, their measurement-based studies are very limited (Guenther et al., 2012;Paton-Walsh et al., 2022). Minimizing uncertainties in estimates of BVOC emissions necessitates further observations (Guenther, 2013). Conducting experiences to evaluate BVOCs fluxes such as leaf-level enclosure, tower and aircraft-based above the canopy is essential to enhance our understanding of the processes influencing BVOC diversity. Furthermore, the recent use of satellite data aims to provide tendencies and variability of VOC emissions in the atmosphere (Bauwens et al., 2022) and can be useful for flux measurements.Réunion Island (21• S, 55• E), located 700 km east of Madagascar and characterized by a complex orography due to its volcanic origin (Gillot and Nativel, 1989), is often considered as a natural laboratory of the exchanges between the atmosphere with the biosphere (ocean and tropical forests).The island presents a tropical climate, specific atmospheric dynamics due to steep slopes covered by forests, boundary layer variations and sea breeze phenomenon, facili...
