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
October 2018: CAC research assistant and former Honours student Jack Simmons graduated and was featured in a UOW press release about his Antarctic research trip.
October 2018: The Greenhouse gases Observing SATellite-2 "IBUKI-2" (GOSAT-2) was successfully launched by the H-IIA rocket from the Japanese Aerospace Exploration Agency (JAXA) Tanegashima Space Center on October 29, 2018. CAC members look forward to years of providing ground-truthing data for GOSAT-2 as well as to using its latest atmospheric products.
October 2018: A study on measurements of some nitrogen oxides in Melbourne air has just been published in Atmospheric Chemistry and Physics. The research was the result of a collaboration between members of the Centre for Atmospheric Chemistry (Stephen Wilson and Nicholas Jones), the University of Melbourne, the Bureau of Meteorology and the University of Heidelberg. The surprising finding was that at a site that is not very polluted by world standards there was a large source of HONO during the day. During some days this represented the dominant source of the hydroxyl radical, the major atmospheric cleansing agent of the atmosphere.
September 2018: Several CAC researchers and PhD students attended the 15th International Global Atmospheric Chemistry (IGAC) Science Conference, which was held jointly with the 14th international Commission on Atmospheric Chemistry and Global Pollution (iCACGP) Quadrennial Symposium in Takamatsu, Japan. CAC Director and IGAC Steering Committee Member Clare Murphy was also in attendance at the pre-conference scientific meetings and met the staff from the journal Atmosphere at their conference booth.

CAC Research Themes
Using global models and developing advanced analysis methods to interpret measurements, probe datasets, and test theories of atmospheric composition and chemistry.
Investigating photodissociation action spectroscopy, radical chemistry and microdroplet dynamics using pulsed-laser spectroscopy and mass spectrometry techniques.
Using remote-sensing spectrometric techniques to quantify emissions from vegetation fires to the atmosphere.
Developing and applying novel techniques to measure greenhouse gas emissions from agricultural practices and identifying effective strategies to mitigate emissions from the industry.
Following changes in particles in the atmosphere to understand their impact, formation, and fate.
