Seasonality of isoprenoid emissions from a primary rainforest in central Amazonia
Alves, Eliane Gomes; Jardine, Kolby J.; Tóta, Júlio; Jardine, Angela B.; Yáñez-Serrano, Ana Maria; Karl, Thomas G.; Tavares, Julia ValentimTropical rainforests are an important source of isoprenoid and other volatile organic compound (VOC) emissions to the atmosphere. The seasonal variation of these compounds is however still poorly understood. In this study, vertical profiles of mixing ratios of isoprene, total monoterpenes and total sesquiterpenes, were measured within and above the canopy, in a primary rainforest in central Amazonia, using a pr...
An overview of the Amazonian Aerosol Characterization Experiment 2008 (AMAZE-08)
Martin, Scot T.; Andreae, Meinrat O.; Althausen, Dietrich; Artaxo, Paulo; Baars, Holger; Borrmann, Stephan H.; Chen, Qi; Farmer, Delphine K.The Amazon Basin provides an excellent environment for studying the sources, transformations, and properties of natural aerosol particles and the resulting links between biological processes and climate. With this framework in mind, the Amazonian Aerosol Characterization Experiment (AMAZE-08), carried out from 7 February to 14 March 2008 during the wet season in the central Amazon Basin, sought to understand th...
Emissions of putative isoprene oxidation products from mango branches under abi...
Jardine, Kolby J.; Meyers, Kimberly T.; Abrell, Leif; Alves, Eliane Gomes; Yáñez-Serrano, Ana Maria; Kesselmeier, Jürgen; Karl, Thomas G.Although several per cent of net carbon assimilation can be re-released as isoprene emissions to the atmosphere by many tropical plants, much uncertainty remains regarding its biological significance. In a previous study, we detected emissions of isoprene and its oxidation products methyl vinyl ketone (MVK) and methacrolein (MACR) from tropical plants under high temperature/light stress, suggesting that isopren...
