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...

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...

Prioritizing climate change adaptation options for iconic marine species Abstract Adaptation options in response to climate impact scenarios for marine mammals and seabirds were developed based on the IPCC vulnerability framework. Under this framework, vulnerability to the physical effects of climate change can be reduced by adaptation options that reduce exposure of individuals, reduce the sensitivity of individuals, and increase the adaptive capacity of individual/species...

Seasonality of biological and physical controls on surface ocean CO2 from hourly observations at the Southern Ocean Time Series site south of Australia Abstract The Subantarctic Zone (SAZ) is important for air-sea CO2 exchange, ventilation of the lower thermocline, and nutrient supply to global ocean productivity. Here we present the fi rst high-resolution autonomous observations of mixed layer CO2 partial pressure (pCO2) and hydrographic properties covering a full annual...
