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 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 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...

Comparisons of in situ carbon dioxide and methane measurements at Cape Grim – an update; and an overview of GCWerks software for in situ data processing Abstract Loh et al. [2013] presented a first look at the Picarro cavity ringdown spectrometer (CRDS) record for continuous measurement of atmospheric CO2, CH4 (and water vapour) from the instrument that was installed at Cape Grim in February 2012. The Picarro record provides a more truly continuous time coverage than the...

Seasonal coastal sea-level prediction using a dynamical model Abstract Sea level varies on a range of time scales from tidal through to decadal and centennial change. To date little attention has been focussed on the prediction of interannual sea-level anomalies. Here, we demonstrate that forecasts of coastal sea-level anomalies from the dynamical Predictive Ocean Atmosphere Model for Australia (POAMA) have significant skill throughout the equatorial Pacific and along the...
