Organic aerosol particles that form in the air above the Amazon rain forest likely arise from potassium-rich droplets emitted from rain forest flora and fauna, especially molds (Science, DOI: 10.1126/science.1223264). So-called secondary organic aerosols form from oxidation of airborne organic gases and play key roles in weather and climate by seeding clouds and absorbing or scattering sunlight, but their origin and . . .
