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
September 2017: A new paper led by CAC PhD student Jesse Greenslade was published in Atmospheric Chemistry and Physics. The paper, titled "Stratospheric ozone intrusion events and their impacts on tropospheric ozone in the Southern Hemisphere" uses a combination of balloon-borne ozonesonde measurements and a chemical transport model to identify and quantify events when ozone is transported from the stratosphere to the troposphere over the southern ocean.
August 2017: CAC members David Griffith, Nicholas Deutscher and Beata Bukosa attended the International Carbon Dioxide Conference (ICDC10) in Interlaken, Switzerland, which was also the 10th anniversary of this event. During the conference they presented the research related to carbon dioxide and the carbon cycle, including observations from the TCCON network, interpretation of in-situ and remote greenhouse gas measurements across Australia and radon tracer flux measurements of different greenhouse gases in agricultural environments.
August 2017: CAC member Jenny Fisher presented an invited talk at the 2017 Atmospheric Chemistry Gordon Research Conference. Her talk, titled "Fates of Volatile Organic Compounds in the Presence of (Some) NOx: Implications for the Remote Atmosphere" was part of a session on Chemistry in the Remote Atmosphere.
July 2017: Laser Chemistry Laboratory PhD student Cameron Bright won back-to-back best poster prizes at the Australian and New Zealand Society for Mass Spectrometry (ANZSMS) conference in Adelaide and then from the Physical Chemistry Division at the RACI Congress in Melbourne.
July 2017: CAC's deputy director Adam Trevitt has been in the news! His group's research using lasers to probe the chemistry at the surface of a single droplet at a time was featured in the Illawarra Mercury, and he also did an interview with the Vox FM 106.9 Illiawarra "Monday Grapevine" radio show.
July 2017: A new paper co-authored by CAC member Jenny Fisher was published in Atmospheric Chemistry and Physics. Led by Christopher Chan Miller from Harvard (a CAC alum!), the paper uses aircraft observations to better understand glyoxal and its use as a constraint for isoprene emissions.
July 2017: CAC member Jenny Fisher took part in the first-ever Science-A-Thon, joining others worldwide who tweeted 12 photos over 12 hours showing a day-in-the-life of scientists of all varieties. The Science-A-Thon doubled as an outreach event and a fundraiser for the Earth Science Women's Network. Check out Jenny's photos & tweets!
July 2017: CAC member and Laser Chem Lab leader Adam Trevitt received the 2017 Michael Guilhaus Research Award. The Guilhaus Award of $10,000, supported in 2017 by Waters and Australian and New Zealand Society for Mass Spectrometry (ANZSMS), is granted to an early career researcher (<10 yrs from award of PhD) to support innovative research in the field of mass spectrometry. The award honours the work of Professor Michael Guilhaus, a pioneer of modern mass spectrometry instrumentation development, and an advocate of early career researchers in Australia.
July 2017: CAC researcher Nicholas Deutscher received $689K in funding from the Australian National Low Emissions Coal Research & Development Targeted Program for the project "Developing and verifying an atmospheric assurance system for the Gippsland near-shore environment." Jointly led by UOW and the University of Melbourne, the project also involves CAC members David Griffith and Travis Naylor.
