Research Highlights

Modern inhalation anesthetics: Potent greenhouse gases in the global atmosphere (2015)

Modern inhalation anesthetics undergo little metabolization during clinical application. From urban areas to the pristine Antarctic environment, we detect a rapid accumulation and ubiquitous presence of several anesthetics in the global atmosphere.

Trifluoromethane (HFC-23) Emissions in East Asia (2015)

Trifluoromethane (CHF3, HFC-23), with a 100-year global warming potential (GWP) of 12400, is regulated under the Kyoto Protocol.

HFC-43-10mee atmospheric abundances and global emission estimates (2014)

This electronics industry celaning solvent is considered only a minor contributor to global radiative forcing; however, our calculated emissions differ significantly from the available reported figures and projected estimates.

Emission estimates from long-term measurements of four new hydrofluorocarbons (HFCs): HFC-245fa, HFC-365mfc, HFC-227ea, and HFC-236fa (2011)

Long-term AGAGE measurements with global coverage are presented for four potent greenhouse gases: a fire-suppressant, a refrigerant, and two commercially-used foam blowing substances.

Renewed Growth of Atmospheric Methane (2008)

After almost a decade with little change in global atmospheric methane mole fraction, measurements from the AGAGE and CSIRO networks show renewed growth starting near the beginning of 2007.

Nitrogen trifluoride in the global atmosphere (2008)

Background atmospheric abundances and trends of nitrogen trifluoride (NF3), a potent anthropogenic greenhouse gas, have been measured for the first time.
