↑Max Planck Society. (2004, February 26). Astonishing Discovery Over The Amazonian Rain Forest. ScienceDaily Citat: "...An international team of scientists from the Max Planck Institute of Chemistry, Mainz, Germany, the University of Antwerp, Belgium, the Ghent University, Belgium, and the University of São Paulo, Brazil, examined natural aerosols from the Amazonian rain forest, and has found that they contained two previously unknown compounds, which are photooxidation products of isoprene. These compounds are hygroscopic and could impact cloud formation, rainfall and climate...This discovery is a breakthrough because for the first time a link can be demonstrated between isoprene emitted by forest vegetation and formation of water soluble fine particles..."
↑Carnegie Mellon University. (2014, May 15). Emissions from forests influence very first stage of cloud formation. ScienceDaily Citat: "...This new study uncovers an indispensable ingredient to the long sought-after cloud formation recipe -- highly oxidized organic compounds..."It turns out that sulfuric acid and these oxidized organic compounds are unusually attracted to each other. This remarkably strong association may be a big part of why organics are really drawn to sulfuric acid under modern polluted conditions," Donahue said...The fine-tuned model not only predicted nucleation rates more accurately but also predicted the increases and decreases of nucleation observed in field experiments over the course of a year, especially for measurements near forests. This latter test is a strong confirmation of the fundamental role of emissions from forests in the very first stage of cloud formation, and that the new work may have succeeded in modeling that influence..."
