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

June 2016: CAC members Clare Murphy and Stephen Wilson and partners from the University of Surrey, University of São Paulo, and North Carolina State University, received a grant from the University Global Partnership Network for research into Next-Generation Environmental Sensing for Local to Global Scale Health Impact Assessment.

June 2016: CAC hosted a class of visiting HSC Chemistry students from Warrawong High School. Current students and recent graduates Max Desservettaz, Bea Bukosa, Joel Wilson, Kaitlyn Lieschke, and Cameron Bright talked to the students about their paths to research degrees and their current research. The students then visited the Laser Chemistry and Atmospheric Chemistry Labs to see science in action! Photos from the visit are available in the photo gallery.

May 2016: A new article led by CAC member Jenny Fisher has just been published in Atmospheric Chemistry and Physics. The study uses aircraft and ground-based data to understand organic nitrates and their impact on the atmospheric NOx budget in an isoprene- and monoterpene-rich environment.

May 2016: CAC director Clare Murphy visited Dr Prashant Kumar at the University of Surrey to discuss plans for a quadrilateral UGPN project on air quality monitoring and modelling.

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.
