Darin W. Toohey
Professor, Department of Atmospheric and Oceanic SciencesPh.D., Harvard University (1988)
In Situ Trace Gas Measurements Group Home Pages
Research Interests
Kinetics, spectroscopic, and field measurements of trace species in the troposphere and lower stratosphere; design and fabrication of fast-response in situ instrumentation.
Teaching Interests
Physics and chemistry of the earth system; optics, electronics, and mechanical design.
Dr. Toohey exploits ultrasensitive spectroscopic techniques for fast-response measurements in the laboratory and field. He has designed and built instruments that have been deployed at the ground and on high-altitude balloons and aircraft. His present research addresses the mechanisms by which inorganic free radicals control the abundances of gases that influence the radiative balance of the earth. Dr. Toohey is presently expanding his research efforts to include laser-based laboratory studies of small particle formation and growth to address the impact of aerosols on earth's changing chemistry and climate.
