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

June 2017: PhD student Beata Bukosa attended a one week Climate Change Winter School at the University of New South Wales in Sydney hosted by the ARC Centre of Excellence for Climate System Science. The winter school focused on the scientific fundamentals of climate change. It also involved sessions where the students could learn how to use the Monash Simple Climate Model and workshops where the participants had to hypothesise the effect of different scenario changes on Earth's climate.

June 2017: PhD student Jesse Greenslade represented CAC at the Faculty of Science, Medicine and Health round of UOW's Three Minute Thesis (3MT) competition. Jesse's presentation, If a tree grows up in the forest, with nobody around to hear it, does it still emit isoprene? explained his thesis research using satellite formaldehyde observations to estimate isoprene emissions in Australia, and why this work matters.

June 2017: Jenny Fisher presented a seminar titled Thinking outside the (grid) box: combining modelling with aircraft observations to understand the nitrogen chemistry of the atmosphere at the University of Sydney's School of Chemistry seminar series.

June 2017: CAC had a strong presence at the recent joint NDACC Infrared working group and TCCON annual meetings at the Universite Pierre et Marie Curie in Paris. Talks were presented by Nicholas Deutscher, David Griffith, Nicholas Jones, Clare Murphy and Voltaire Velalzco who also presented a poster.

June 2017: Clare Murphy attended two days of talks and workshops related to the UGPN NEST-SEES project at the University of Surrey (June 5th and 6th). She delivered a lecture on open-path measurements for air quality assessment and took part in panel discussions regarding future challenges for air quality, climate and health. She has been recognised as an official collaborator in the newly establised Global Centre for Clean Air Research at the University of Surrey.

May 2017: CAC PhD student Beata Bukosa visited Dylan Jones' research group at the University of Toronto. Beata worked on the creation of a new carbon simulation in the 3D Global Chemical Transport Model GEOS-Chem. This new simulation will couple the currently separate CO2, CH4 and CO simulations which should improve the representation of these gases in the model. During this visit Beata also attended the 5th Carbon Assimilation Workshop where she presented her work and introduced the joint CO2-CH4-CO simulation project she was working on with the Jones group.

May 2017: Students Bea Bukosa and Jesse Greenslade and researcher Jenny Fisher represented CAC at the 8th International GEOS-Chem Conference at Harvard University. Between them, they presented two posters and a talk, attended several model clinics, and ran a working group meeting!

April 2017: Jenny Fisher spent two weeks as a Visiting Scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, USA. During her visit, she spent time working with collaborators from NCAR's Atmospheric Chemistry Observations & Modeling group and presented a seminar on the Impacts of organic nitrates on the NOx budget.

April 2017: CAC joins forces with Japan’s NIES and the Energy Development Corporation of the Philippines to establish the first Total Carbon Column Observing Network Station in Southeast Asia. A unique collaborative project spearheaded and coordinated by CAC researcher Voltaire Velazco with mentor David Griffith brings together UOW, the Energy Development Corp. (EDC Philippines), a world leader in geothermal energy production, and Japan’s National Inst. for Environmental Studies (NIES) - Japan’s forefront in environmental research, to establish a total carbon observing column network (TCCON) station in the Philippines, described in a new paper led by Voltaire. TCCON Philippines will be the primary tropical validation site for Japan’s GOSAT-2 satellite and is already providing data to NASA’s OCO-2 mission.

April 2017: CAC undergrad (and future Honours student) Jack Simmons' 51-day voyage to Antarctica earlier this year has been profiled in the video Journey of a lifetime and story Out to Sea by UOW's The Stand publication.
