Research Highlights

What were the trace gas and particulate emissions from the 2003 southern California wildfires? (2007)

In October 2003, thirteen major wildfires in southern California burned more than 300,000 hectares of mainly chaparral biome, strongly impacting an urban area populated by ~20 million people.

Observations of 1,1-difluoroethane (HFC-152a) at AGAGE and SOGE monitoring stations 1994-2004 and derived global and regional emission estimates (2007)

We have taken a 10-year record of observations of a gas used predominantly in hand-held foam blowing canisters and assessed the state of its trends in the atmosphere.

HFC-245fa and HFC-365mfc — New foam-blowing hydrofluorocarbons (HFCs) on the horizon (2006)

The regulations of the Montreal Protocol on Substances that Deplete the Ozone layer and its Amendments and Adjustments has led to the phase-out of chlorofluorocarbons (CFCs) and hydrofluorochlorocarbons (HCFCs) in the rigid foam blowing sector.

Retention behaviour of volatile C1-C3 fluoroalkanes upon selected preconcentration adsorbents. I. Carbon molecular sieves and activated charcoals (2006)

This paper describes experimental methods and presents results for the adsorption of atmospherically important gases on carbon-based solid adsorbent materials used principally in our on-site ADS-GCMS instruments.

Global trends, seasonal cycles and European emissions of dichloromethane, trichloroethene and tetrachloroethene from the AGAGE observations at Mace Head, Ireland and Cape Grim, Tasmania. (2006)

Chlorinated hydrocarbons are emitted to the atmosphere from their widespread use as solvents in diverse industrial, commercial and domestic applications.

Can recent growth rate anomalies in the greenhouse gases be attributed to large-scale biomass burning events? (2005)

A significant annual increase in the rate of CO2 accumulation was observed at the Mace Head (Ireland) AGAGE station during 2002-2003. While unexpected, the increase was in close agreement with a similar increase reported in Hawaii.
