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
July 2015: A second paper featuring CAC's collaborative work on the Southern Hemisphere Model Intercomparison Project (SHMIP) has just been published in Atmospheric Chemistry and Physics. CAC members Jenny Fisher, Clare Murphy, Nicholas Jones, and David Griffith contributed to this analysis of global model ability to represent atmospheric CO and HCHO in the Southern Hemisphere, pointing to large uncertainties in biogenic emissions and chemistry. A companion paper led by CAC was published earlier this year.
June 2015: PhD student and Laser Chemistry Laboratory member Christopher Hansen has a new publication in a themed issue of the journal Physical Chemistry Chemical Physics. The paper is based on his work studying the gas-phase ultraviolet photochemistry and photophysics of protonated quinoline, a nitrogen-containing ion and an important building block of molecules that are found in functional materials and may play a role in interstellar and extraterrestrial chemistry.
