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

May 2019: CAC PhD student Beata Bukosa and researcher Jenny Fisher attended the 9th International GEOS-Chem Meeting (IGC9) at Harvard University. Beata presented her work developing a new model capability to simultaneously simulate multiple carbon greenhouse gases, and both attended the myriad talks, posters, clinics, and model development working group. Jenny also attended the GEOS-Chem Steering Committee meeting held after the conference.

May 2019: OCO-3, the Orbiting Carbon Observatory 3 satellite, launched successfully from Cape Canaveral on Saturday 4th May on its way to the International Space Station. CAC researchers are closely involved in the validation of OCO carbon dioxide measurements.

April 2019: CAC researcher David Griffith presented an invited lecture on the impact of isotopic variations on measurements of atmospheric greenhouse gases at the European Geophysical Union 2019 General Assembly. He also presented papers on open path FTIR greenhouse gas measurements as part of the Gipnet project for detecting fugitive GHG plumes, and solar remote sensing at the Burgos, Philippines site (all with other UOW coauthors).

March-April 2019: CAC researcher David Griffith visited the Korean Research Institute for Standards and Science (KRISS, S. Korea) and Laboratory for Science of Climate and Environment (France) to advise and collaborate on applications and use of the UoW-Ecotech Spectronus Greenhouse Gas analyser and on solar remote sensing measurements. The Spectronus is being introduced into the pan-European ICOS (Integrated Carbon Observing System) greenhouse gas measurement and research programs.

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.
