The natural cycles of exchange of substances between the biosphere and the atmosphere are of major relevance to the Earth's climatic system. Perhaps the best-known example of this is the carbon cycle ...

The terrestrial vegetation emits large amounts of volatile organic compounds (VOC) into the atmosphere, which on oxidation produce secondary organic aerosol (SOA). By acting as cloud condensation ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The Amazon is also known as the Green Ocean, for the way ...

Deep in the Amazon, high above the rainforest, clouds sprout from the thick atmosphere, their condensed water vapor billowing into the blue sky beyond. Underneath this, on the ground but acutely aware ...

When new particles develop in the atmosphere, this influences cloud formation and with that the climate too. Since a few years, these complex processes have been reproduced in a large air chamber ...

Easily spotted by their honeycomb shape, open-cell clouds are one of the most common cloud formations, found on the backside of low pressure systems and skirting the edges of every continent. Yet for ...

Researchers discovered that plants, such as trees and shrubs, can promote the formation of more cloud seeds by means of gaseous hydrocarbons of so-called sesquiterpenes. This finding could reduce ...
