             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.",
