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

November 2016: CAC member Jenny Fisher and UOW climate scientist Helen McGregor published an article in The Conversation on the value of NASA's Earth Science research.

November 2016: CAC members celebrated the 40th Anniversary of the Cape Grim Baseline Air Pollution Station with a commemorative ceremony, a visit to the station, and three days of science at the Atmospheric Composition and Chemistry Observations and Modelling Conference. CAC academic Stephen Wilson, who was Officer in Charge at Cape Grim from 1988-1992, played an important role in the proceedings: leading part of the station visit and jointly cutting the celebratory cake during the ceremony.

November 2016: CAC Deputy Director Adam Trevitt visited China as part of the ATSE's YSEP China-Australia program. Seven Universities in 10 days: Beijing Normal, Peking, Beijing Int. Tech., Dalian Chemical Physics, USTC (NRSL), Shanghai Jiao Tong and Shanghai U. Amazing journey - so much exciting science.

November 2016: In the latest round of funding from the Australian Research Council, CAC Deputy Director Adam Trevitt and collaborators were awarded a Discovery Project on Formation, photochemistry and fate of gas-phase peroxyl radicals. CAC associate member Sandy Burden was awarded a Discovery Early Career Researcher Award on Statistical tools for assessing effects of environmental change.

October 2016: CAC member Jenny Fisher received one of three 2016 L'Oreal-UNESCO For Women in Science fellowships awarded in Australia. She will use the fellowship funding to improve the resolution of the GEOS-Chem atmospheric chemical transport model over Australia. Her current work and plans for the fellowship are described in more detail in this video and this media release.

October 2016: CAC members Clare Murphy and Travis Naylor hosted a CSIRO Scientists in Schools ASSETS Indigenous high school student for work experience. Grace Kalinin did an excellent job using low cost sensors to monitor PM2.5 levels around the M1 highway.

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.
