abstract = "Isoprene dominates global non-methane volatile organic compound
emissions, and impacts tropospheric chemistry by influencing
oxidants and aerosols. Isoprene emission rates vary over several
orders of magnitude for different plants, and characterizing this
immense biological chemodiversity is a challenge for estimating
isoprene emission from tropical forests. Here we present the
isoprene emission estimates from aircraft eddy covariance
measurements over the Amazonian forest. We report isoprene
emission rates that are three times higher than satellite top-down
estimates and 35% higher than model predictions. The results
reveal strong correlations between observed isoprene emission
rates and terrain elevations, which are confirmed by similar
correlations between satellite-derived isoprene emissions and
terrain elevations. We propose that the elevational gradient in
the Amazonian forest isoprene emission capacity is determined by
plant species distributions and can substantially explain isoprene
emission variability in tropical forests, and use a model to
demonstrate the resulting impacts on regional air quality.",
