Daniel S. Burgess

A team of researchers from Harvard University in Cambridge, Mass., and from NASA's Jet Propulsion Laboratory in Pasadena, Calif., has employed ultraviolet resonance fluorescence to identify an ozone-destroying molecule in the stratosphere for the first time. The findings will enable atmospheric scientists to better predict variations in the ozone layer and subsequent changes in ultraviolet exposure at the surface. Scientists used an airborne instrument to detect the presence of the chlorine monoxide dimer in the polar atmosphere by UV resonance fluorescence. The instrument was carried...Read full article
