What is in the Air We Breathe?


“What we do in my group is we zoom in on the aerosols.”

Vicki Grassian and her team look at aerosols at a microscopic level to determine their impact on our health and our climate. Aerosols can be mineral dust and sea spray from the ocean or created by human activity or stem from any number of sources. They can travel across the globe impacting people, animals, and the planet in their wake.

Grassian’s work seeks to understand how aerosols and other gases not only affect us but how we might harness them for solar geoengineering.
