tropical cyclone projections

Posted by on Jan 20, 2016 in Abstracts, Abstracts 2015

Refining Australian region tropical cyclone projections Abstract Decision-makers require high quality projections of future tropical cyclone (TC) behaviour, especially coastally impacting TCs.  However, the latest international TC projection studies provide contradictory results on changes in TC activity, with some showing increases and others decreases in TC numbers both globally and in the Australian region. As a consequence our confidence in projections has been set...

Greenhouse gas observing networks

Posted by on Jan 20, 2016 in Abstracts, Abstracts 2015

Designing optimal greenhouse gas observing networks for Australia Abstract Atmospheric transport inversion is commonly used to infer greenhouse gas (GHG) flux estimates from concentration measurements. The optimal location of ground based observing stations that supply these measurements can be determined by network design. Here, we use a Lagrangian particle dispersion model (LPDM) in reverse mode together with a Bayesian inverse modelling framework to derive optimal GHG...

Fourier transform spectrometer results from the Gunn Point campaign, June 2014, including emission factors of greenhouse gases from savanna fires. Abstract In June 2014 an intensive measurement campaign took place at Gunn Point in the Northern Territory primarily aimed at characterising the emissions from early dry season savanna fires. A Fourier transform spectrometer was deployed and from this the concentration of CO2, CO, N2O, CH4 and 13CO2 over the measurement campaign...

Cloud feedbacks in ACCESS and CMIP5 models

Posted by on Jan 20, 2016 in Abstracts, Abstracts 2015

Cloud feedbacks in ACCESS and CMIP5 models Abstract Cloud feedbacks provide the greatest source of uncertainty in projections under given greenhouse gas scenarios, and are currently the subject of intense international scrutiny.  Quantifying, understanding and evaluating cloud feedbacks therefore remain top-priority tasks for quantifying projection uncertainty, assessing confidence in models and narrowing the range of future projections.  Evaluating cloud feedbacks in...

Gunn Point

Posted by on Jan 19, 2016 in Abstracts 2014

Gunn Point Field Savannah Campaign Abstract Queensland University of Technology (QUT) participated in the Gunn Point Field Savannah Campaign, held at the Australian Tropical Atmosphere Research Station at Gunn Point, Northern Territory between 28 May and 28 June 2014. The campaign was conducted in collaboration with the CSIRO, Bureau of Meteorology, University of Wollongong, Macquarie University and Aerodyne Research. Measurements were performed on aerosol primarily emitted...
