What’s really important when you get down to thinking of global climate, and how could these measurements affect you?

Using Particles to Visualize Climate

Murray Johnston explains how his research group utilizes their data to visualize what is happening in our atmosphere.


Murray V. Johnston III is a professor of chemistry and biochemistry at the University of Delaware. His research focuses on applying mass spectrometry to determine changes in matter, specifically related to problems of atmospheric, environmental, and biological significance.

Engaging Scientists and Others through Visuals

When people connect to something, they talk about it. Murray V. Johnston III discusses why the connection is necessary to climate-change science. 


Instruments like mass spectrometers are an important method by which scientists can study changes in the air at the most minute levels, even the level of nanoparticles. While we can’t see all the changes in the air that might affect things like cloud formation or climate, Johnston’s research provides us with a fundamental understanding of particles in the air and the various factors at work that change how particles form, react, and behave.
