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

April 2016: A new article co-authored by CAC member Jenny Fisher has just been published in Atmospheric Chemistry and Physics. Led by Karen Yu (Harvard), the paper investigates the sensitivity of a chemical transport model to grid resolution when simulating chemistry under high-isoprene conditions.

March 2016: CAC has a new paper, led by Travis Naylor, in Animal Production Science. This paper was 1 of 4 published as part of the national manure management program we were involved in for the last 3 years.

March 2016: CAC welcomed Iris Dion to the group. Iris has a masters degree from the University Pierre & Marie Curie, and will be spending the next few months working with Jenny Fisher and collaborators at Macquarie University to model the Australian mercury cycle. Iris' research assistantship is funded by CAC and a small grant from the Faculty of Science, Medicine and Health. 

March 2016: CAC member Jenny Fisher attended Science Meets Parliament 2016 as a representative of the Australian Meteorological & Oceanographic Society. Read more about the experience in the Bulletin of the Australian Meteorological & Oceanographic Society.

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.
