Volcanic plume likely to dissipate in days
U. COLORADO (US)—The eruption of an Icelandic volcano that sent a huge plume of ash into the atmosphere and caused sweeping disruptions of air traffic over Great Britain and Scandinavia on April 15 will likely dissipate in the next several days, according to atmospheric scientist Brian Toon.

Inland air spiked with chlorine
U. WASHINGTON / U. COLORADO (US)—A new study suggests that chlorine, a chemical usually kicked into the atmosphere by sea spray, is more abundant than expected in air far from any coastline, and looks to be interacting with man-made pollution at night in ways that might affect air quality and climate.
