ACD and TIIMES scientists detected significant fluxes and concentrations of methyl salicylate (MeSA) in a tree plantation atmosphere using micrometerological techniques in combination with highly sensitive mass spectrometry.

A recent study by scientists from ACD and the Mexican government concluded that Mexico City?s ambient ozone (O3) can be reduced by decreasing emissions of volatile organic compounds (VOCs); while decreases in emissions of nitrogen oxides (NOx) may be less effective, and possibly even counterproductive, in reducing local O3 concentrations.

Researchers at NCAR and the Australian Institute of Marine Science suggest that natural processes, ocean thermostat, appear to be regulating sea surface temperatures in a biologically diverse region of the western Pacific Ocean, thereby protecting some of the worlds largest coral reefs from the impacts of climate change.
