Volcanic ash is no ordinary dust: It gets injected into the atmosphere, climbs to the stratosphere, impacts climate, powders roadways and clogs jet engines. To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, Cornell researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range. The work is helping scientists uncover how this tiny material - measured in microns and nanometers - plays a big role in the atmosphere.
