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

August 2018: CAC researcher Nicholas Deutscher was awarded an ARC Future Fellowship to work on measuring greenhouse gases in the atmosphere and understanding what causes their variability. His project, Novel techniques for interpreting atmospheric variability and its drivers, will make extensive use of the AirCore measurement technique in and existing measurements made by CAC, combined with atmospheric modelling, to improve greenhouse gas emissions estimates and understand how these are likely to evolve in a changing climate.

July 2018: CAC PhD student Beata Bukosa represented the School of Chemistry at the faculty round of the Three Minute Thesis (3MT) competition. As the Faculty of Science, Medicine and Health Judge's Winner, she was chosen to represent the faculty at the final round of UOW's 3MT competition with the other faculty round winners. Her talk title was Missing pieces: Imitating our Earth system, and she talked about the importance of greenhouse gas measurements and modelling in Australia.

July 2018: CAC Director Clare Murphy has been appointed Section Editor-in-Chief for "Air Quality" for the journal Atmosphere.

Laser Photochemistry and Spectroscopy: 

Investigating photodissociation action spectroscopy, radical chemistry and microdroplet dynamics using pulsed-laser spectroscopy and mass spectrometry techniques.

CAC_fires

Fire Emissions: 

Using remote-sensing spectrometric techniques to quantify emissions from vegetation fires to the atmosphere.

CAC_agriculture

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.
