Vejrvirkning[redigér | redigér wikikode]
Visse bioaerosoler i atmosfæren (kan) reagere med visse stoffer og bliver hygroskopiske og er med til at danne skyer og tåge. Det viser sig at mange landplanter danner store mængder af bioaerosolen isopren og visse udbredte planktonarter danner store mængder af bioaerosolen dimethylsulfid.

ScienceDaily Citat: "..."We think we measured all major components of the hydroxyl radical reactants, but there is something still unaccounted for,” says Brune. "We know that something we cannot identify is reacting with the hydroxyl radicals and we know it is temperature dependent and not light dependent. We just do not know what it is."..."

They make hundreds of millions of tons of this chemical...for reasons that we still do not fully understand."..."

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..."
