A case of the vapours: source of ‘climate-active’ organic aerosol particles pinned down

From Forschungszentrum Juelich , comes what looks to be a pretty important discovery about how plant emitted aerosols like Great Smoky Mountains National Park haze comes about and grows large enough to reflect significant sunlight, something climate models don’t yet fully account for. Major enigma solved in atmospheric chemistry Nature: Researchers discover source of climate-active…
