The role of goop: Research shows pollution doesn't change the rate of droplet formation

actly what is going on with that cloud, and this allows for very accurate measurements of cloud formation."

Beginning in 2004, Nenes and his graduate students took the chamber along on ten missions operated by NASA, NSF, NOAA and ONR. They flew through the pristine air of the Arctic, smoke from forest fires in Canada, and polluted air masses over the United States. They also sampled polluted air over Mexico City, clean air over the forests of Finland, and dust-laden air over the Mediterranean. Though the particles flowing through the cloud chamber were different each time, the rate at which they formed droplets, the condensation coefficient, remained the same.

"We have literally hundreds of hours of data studying cloud formation from areas all over the globe," Nenes said. "We didn't see any changes in the droplet nucleation time scale."

In future studies, Nenes would like to study particles from other areas of the world, especially Africa and China. He'd also like to see what happens when the temperature of the air flowing through the cloud chamber is cold enough to form ice. There is some evidence that the kinetics of ice formation may be different in particles that are rich in "goop."

The study of droplet formation provides one small step toward reducing the uncertainty in climate modeling.

"This is good for atmospheric and climate scientists, because some of the uncertainty of droplet formation and aerosol impacts goes away," Nenes added. "With careful measurements and global deployment of measuring instruments, you can actually resolve outstanding questions in cloud physics and help simplify the descriptions of clouds in climate models."
