Atmospheric Chemistry

CSIRO's Climate, Nature and Community Resilience program is seeking a Reactive Gases Scientist to join the Atmospheric Chemistry – Climate and Air Pollution team. The team combines observations, atmospheric chemistry and modelling to provide critical scientific information that informs responses to air quality and climate change challenges. In this role, you will lead and develop a portfolio of long-term and campaign-based observations of key reactive gases and their interactions with atmospheric composition and climate. Your research will span surface ozone, oxidized nitrogen compounds and volatile organic compounds, as well as aerosol chemistry and the formation of secondary organic aerosols. You will operate and develop advanced research-grade instrumentation, lead the delivery of high-quality observational datasets and work across nationally and globally significant platforms, including the Kennaook – Cape Grim Baseline Air Pollution Station and the Research Vessel Investigator. Working with CSIRO, government, academic, industry and community partners, you will translate atmospheric chemistry expertise into practical solutions with real impact. Role particulars Location and office arrangements: CSIRO Aspendale, Melbourne, VIC Salary: AU$135k – AU$158k per annum (pro rata for part-time), plus 15.4% superannuation Tenure & work schedule: Indefinite. Part-time, job-share and flexible work arrangements may be explored based on the needs of the role and individual circumstances. Reference: 103946

A normally two-year postdoctoral appointment beginning in autumn 2027 supports original environmental research with faculty mentorship at Caltech. Fields include climate dynamics and adaptation, atmospheric chemistry, physical oceanography, glaciology, paleoclimate, biogeochemistry and environmental microbiology. The annual stipend is $80,000, with a $10,000 research-expense fund and up to $1,500 for travel to Pasadena. Continuation depends on first-year progress and completion of the doctorate. Applicants may also be considered for other relevant Caltech postdoctoral positions.
