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.

CAC Research Themes

CAC_measurements

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.

CAC_model

Modelling and Analysis: 

Using global models and developing advanced analysis methods to interpret measurements, probe datasets, and test theories of atmospheric composition and chemistry.

CAC_laser

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.

Radiation - SIPEX

Solar Radiation and Aerosols: 

Following changes in particles in the atmosphere to understand their impact, formation, and fate.
