The atmosphere is replete with aerosols made up of organic molecules, which are necessary for clouds to form, as well as for rain and other forms of precipitation to fall. However, how these organic aerosols form has largely remained a mystery to atmospheric scientists. Now, a new study published in Science this week (August 30) shows that salt compounds released by plants and fungi hover above the Amazon Rainforest, where the may exert a significant impact on the region’s weather by contributing to s aerosols to the atmosphere and serving as seeds for cloud and rain formation.
An international team of researchers led by biogeochemist Meinrat Andreae of the Max Planck Institute for Chemistry in Germany found the particles by climbing up a 262-foot tower and collecting air samples, PhysOrg reported. The main source of these particles, which are rich in potassium, is likely fungal spores, which have a gel ...
