The Impact of Aerosols on Atmospheric Chemical Cycles
Quick fact
A single sulfate aerosol particle can destroy thousands of ozone molecules before falling to the ground, and aerosols are why the 'ozone hole' appears over Antarctica during spring.
Why this is interesting
You've heard that aerosols cool the planet by reflecting sunlight—but did you know they also act as tiny chemical factories that tear apart and rebuild the very molecules in our atmosphere?
