Centre for Atmospheric Chemistry

Welcome to
the Centre for Atmospheric Chemistry

Research at the Centre for Atmospheric Chemistry advances understanding of atmospheric trace gas and aerosol chemistry, atmosphere/biosphere exchange of trace gases, and long term changes in atmospheric composition and chemistry - from the laboratory to the field and at local to global scales.

Over more than 20 years, we have established the most intensive atmospheric composition and chemistry research and training program in Australian universities. We collaborate widely in Australian and international atmospheric science communities including other universities, CSIRO, ANSTO, BOM, federal and state government departments and international networks.

Recent CAC News

August 2016: CAC made an impressive showing at the Australia-New Zealand Aerosol Assembly with talks by CAC members Clare Murphy and Steve Wilson and PhD student Doreena Dominick. Also in attendance were postdoc Elise-Andree Guerette and honours student Tom Keatley, as well as our visitor and UGPN partner Prashant Kumar from the University of Surrey.

July 2016: CAC member Jenny Fisher gave an invited presentation on atmospheric organic nitrates at the Telluride Science Research Center Workshop New Insights into Gas-Phase Atmospheric Chemistry, held in Telluride, Colorado USA. Travel costs were provided by travel grants from The Ian Potter Foundation and the UOW Faculty of Science, Medicine and Health.

July 2016: CAC PhD student Matthew Prendergast from the Laser Chemistry Lab was awarded a prize for an outstanding poster presentation by the RSC Gas Kinetics Group at the 24th International Symposium on Gas Kinetics and Related Phenomena (York, UK).

July 2016: CAC member Berywck Poad and collaborators have broken a world record by synthesising the strongest base ever made. Their work was profiled in an article in Chemistry World.

July 2016: CAC director Clare Murphy has been named as one of the new UOW Women of Impact. Clare was interviewed about her research by WIN TV News in a segment that aired the night of the Women of Impact launch. For more details, read about Clare's experiences From the Arctic to Western Sydney.

CAC Research Themes


Trace Gas Measurements: 

Determining the amounts, sources and sinks of atmospheric trace gases with solar remote sensing, in situ and flux measurements, including operating two sites in the TCCON and NDACC networks.


Modelling and Analysis: 

Using global models and developing advanced analysis methods to interpret measurements, probe datasets, and test theories of atmospheric composition and chemistry.


Laser Photochemistry and Spectroscopy: 

Investigating photodissociation action spectroscopy, radical chemistry and microdroplet dynamics using pulsed-laser spectroscopy and mass spectrometry techniques.


Fire Emissions: 

Using remote-sensing spectrometric techniques to quantify emissions from vegetation fires to the atmosphere.


Agricultural Emissions: 

Developing and applying novel techniques to measure greenhouse gas emissions from agricultural practices and identifying effective strategies to mitigate emissions from the industry.

Radiation - SIPEX

Solar Radiation and Aerosols: 

Following changes in particles in the atmosphere to understand their impact, formation, and fate.
