Mark Zondlo and his research team frequently find themselves 45,000 feet above the Earth looking for water vapor in the upper reaches of the atmosphere. From a seat in a National Science Foundation (NSF) research jet, the engineers can search a slice of the sky for pollutants and gases that play a role in climate change. Zondlo, an assistant professor of civil and environmental engineering, said that water plays a greater role in climate change than many people imagine. “If we want to un
