Greenhouse gas network design using backward Lagrangian particle dispersion modelling – Part I: Methodology and Australian test case Abstract This paper describes the generation of optimal atmospheric measurement networks for determining the CO2 fluxes over Australia using inverse methods. A Lagrangian particle dispersion model is used in reverse mode together with a Bayesian inverse modelling framework to calculate the relationship between weekly surface fluxes and...

Reconciling Ground-Based and Space-Based Estimates of the Frequency of Occurrence and Radiative Effect of Clouds around Darwin, Australia Abstract The objective of this paper is to investigate whether estimates of the cloud frequency of occurrence and associated cloud radiative forcing as derived from ground-based and satellite active remote sensing and radiative transfer calculations can be reconciled over a well instrumented active remote sensing site located in Darwin,...

Antarctic sea ice response in ensemble CMIP5 historical and ozone perturbation simulations Abstract The net Southern Hemisphere sea ice area has a small statistically significant positive trend in recent decades in contrast to the decay in the Arctic sea ice cover. There have been a number of theories suggesting that it is driven by strengthening of SAM as a result of ozone depletion; increasing stratification of the ocean from sea ice melt and/or ice shelf melting,...

The Antarctic Ozone Hole during 2011 Abstract The Antarctic ozone hole of 2011 is reviewed from a variety of perspectives, making use of various data and analyses. The ozone hole of 2011was relatively large in terms of maximum area, minimum ozone level and total ozone deficit, being ranked amongst the top 10 in terms of severity of the 32 ozone holes adequately characterised since 1979. In particular, the estimated integrated ozone mass effectively removed within the ozone...

Evaluation of ACCESS model clouds over the Southern Ocean using synthetic brightness temperature program and COSP package Abstract Sea Surface Temperature (SST) warm bias in the Southern Ocean (SO) is a common problem in most climate models. We investigate the causes of this problem by performing comparisons between the modeled cloud and radiative properties and satellite observations. We use the Australian Community and Climate Earth System Simulator (ACCESS) model to...

Archiving of Cape Grim air Abstract Regular collection of Cape Grim air in high pressure metal cylinders for the purpose of maintaining an archive of atmospheric composition has continued since 1978. A history of sampling events, protocols, techniques and re-construction of atmospheric trace gas records through 1995 has been given previously [Langenfelds et al., 1996 and references therein] and updated through 2008 [Lan-genfelds et al., 2011 and references therein]. Recent...
