The Amazon’s Secret Aerosol Factory: Solving a 20-Year Atmospheric Puzzle

Tropical regions like the Amazon exhibit high concentrations of aerosol particles in the upper troposphere, puzzling scientists for decades. Scientists have discovered that isoprene, a plant-emitted hydrocarbon, drives aerosol particle formation in the cold upper troposphere of tropical regions. Trace acids amplify this process, linking tropical emissions to cloud formation and climate dynamics. These findings [...]
