John Gille is the 2008 George W. Goddard winner in recognition of his outstanding research and significant accomplishments in building instruments and interpretation of results in the monitoring of the atmosphere, in particular on the High Resolution Dynamics Limb Sounder ( HIRDLS ). More...
Stratospheric Injections to Counter Global Warming Could Damage Ozone Layer. An idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth's protective ozone layer, new research concludes. The study, led by Simone Tilmes of NCAR's Atmospheric Chemistry Division... Science Express - April 24, 2008. More...
Announcements
Julia Lee-Taylor was recently promoted to Project Scientist II. Julia is in the Chemical Process Modeling group and works with process models, simulating detailed tropospheric oxidation chemistry and soil nitrogen chemistry within the CCSM, collaborating with research on snow photochemistry, trace gas sources, and UV effects on biology and human health.
