Investigating the interplay between ocean, earth and atmosphere
Dr. Chang studies aerosol particles in the air – where they come from, and how they change, move and impact current weather and longer-term climate change. Having completed a postdoctoral fellowship at Harvard, she’s spent thousands of hours in the field on ships and in coastal regions studying the atmosphere and its interplay with the ocean.
We need to understand how energy, gases and particles are exchanged between the atmosphere and the ocean. It’s not a simple process and it can go in both directions. There are layers on top of the ocean that prevent gases from absorbing, there are waves, there are storms, there is sea spray, they can all have an impact. And the ultimate question is, how do they affect climate?
