Susan Solomon, an atmospheric chemist with the National Oceanic and Atmospheric Administration (NOAA) in Boulder, Colo., has been presented with the American Meteorological Society's Henry G. Houghton Award for her research into ozone deterioration. Solomon received the award at the society's annual meeting in New Orleans last month. She was cited for "outstanding theoretical and observational research on atmospheric constituent structure and for significant contributions to understanding the Antarctic ozone hole."
