My research addresses the role of trace gases and aerosols on Earth's climate, atmospheric oxidation, and air quality. We develop instruments for fast-response in situ measurements from the ground, balloons, and aircraft.  We have participated in  more than  50 field campaigns over three decades to examine topics such as stratospheric ozone depletion over the Arctic, the impact of rockets on stratospheric chemistry, long-range transport of pollutants, and the role of aerosols in modification of cloud properties. have conducted work in Antarctica, Spitsbergen, New Zealand, Sweden, Nepal, the Virgin Islands, Alaska, Hawaii, and throughout the continental United States.  For more details, see
Google Scholar, on, and ResearchGate. We recently moved into the new Sustainability, Energy, and Environment Complex (SEEC) on East Campus. We recently completed a series of successful measurements of cloud water contents from the NCAR Gulfstream-V aircraft as part of the ORCAS field campaign, and we are flying our cloud water instrument on the NASA DC-8 aircraft as part of the KORUS-AQ campaign based in South Korea.

Prof. Toohey is involved in various activities at CU and in the scientific community. He currently serves as the faculty director of the Sustainability and Social Innovation Residential Academic Program (SSI RAP) located at William Village North, the first LEED platinum residence hall at CU Boulder.

Science Policy

In 2011-2012, Prof. Toohey served as a Jefferson Science Fellow at the U.S. Department of State in the Bureau of East Asian and Pacific Affairs, working on issues related to energy and green growth for APEC,
issues that are featured in the President's Climate Action Plan. He attended the 10th APEC Energy Ministerial Meeting in St. Petersburg, Russia, and organized a workshop on Climate Change Adaptation in Singapore. Since returning to CU,
he helped develop proposals for hosting a hub of the Future Earth Secretariat in the United States and for linking
educators at CU working in the fields of sustainability and global development.
