Measurements at Cape Grim

Posted by on Oct 29, 2015 in Abstracts, Abstracts 2014

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

Posted by on Oct 29, 2015 in Abstracts, Abstracts 2015

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

Posted by on Oct 29, 2015 in Abstracts, Abstracts 2015

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...

Antarctic Ozone Hole during 2012

Posted by on Sep 1, 2015 in Abstracts, Abstracts 2014

The Antarctic Ozone Hole during 2012 Abstract We review the 2012 Antarctic ozone hole, making use of various meteorological reanalyses, remotely sensed ozone measurements and ground-based measurements of ultra-violet radiation. Based on analysis of 33 years of satellite records, we find that the ozone hole of 2012 was one of the least severe since the late 1980s in terms of maximum area, minimum ozone level and total ozone deficit. In particular, the estimated integrated...

Declining aerosols in CMIP5 projections

Posted by on Sep 1, 2015 in Abstracts, Abstracts 2014

Declining aerosols in CMIP5 projections: effects on atmospheric temperature structure and midlatitude jets Abstract We assess the effects of declining anthropogenic aerosols in Representative Concentration Pathway 4.5 (RCP4.5) in four models from the Coupled Model Intercomparison Project Phase 5 (CMIP5), with a focus on annual, zonal-mean atmospheric temperature structure and zonal winds. For each model, we diagnose the effect of declining aerosols from the difference...
