This data collection contains various phases of the Coupled Model Intercomparison Project (CMIP) experiments and relevant data processed from the CMIP collections for climate research such as third phas of CMIP and fifth phase of CMIP. The data collection originates from the World Climate Research Programme (WCRP) Working Group of Coupled Modelling (WGCM) with 20 climate modeling groups from around the world and input from the IGBP AIMES project agreed to promote a new set of coordinated climate model experiments. The latest experiments comprise the fifth phase of the Coupled Model Intercomparison Project (CMIP5). CMIP5 will notably provide a multi-model context for 1) assessing the mechanisms responsible for model differences in poorly understood feedbacks associated with the carbon cycle and with clouds, 2) examining climate predictability and exploring the ability of models to predict climate on decadal time scales, and, more generally, 3) determining why similarly forced models produce a range of responses. The data collection represents the contributions to WCRP’s climate experiments by our Australian climate model runs and the international collection of climate model runs for the coupled model intercomparison project (CMIP) hosted through the ESGF. This data collection underpins many scientific works in the Australian funded research in climate variability, change and adaption as well as the participation of Austalian scientists in the IPCC Assessment report. Currently we are preparing the 5th Assessment Report (AR5) for the Intergovernmental Panel on Climate Change (IPCC) based on the CMIP5 data collection.

Collection of meteorological weather analysis and forecast model output from the Bureau of Meteorology using the Australian Community Climate and Earth System Simulator (ACCESS) numerical weather prediction for various domains, such as global, regional, and city/state. The data collection comes from the Bureau’s daily operational numerical weather prediction analyses and forecasts from the period since the ACCESS system became operational in 2009, as well as significant ACCESS NWP research experiments. The analyses are output from the ACCESS version of the UK Met Office 4DVAR software and the forecast data is output from the ACCESS version of the UK Met Office Unified Model software. Data are in the same formats that are used internally in the Bureau’s operational systems. For analyses and forecasts, the data are in grib or netCDF formats; model-specific formats are used for observations, model initial and boundary conditions and other associated files.

ACCESS-S1 is the Australian Bureau of Meteorology’s seasonal prediction system used for multi-week and seasonal prediction. The archive provides access to the hindcast set i.e., forecasts run retrospectively for dates in the past. The hindcast set consists of an 11 member ensemble from the 1st, 9th, 17th, and 25th of every month for the period 1990-2012. ACCESS-S1 is based on the UK Met Office GloSea5-GC2 seasonal prediction system, but has enhancements to the ensemble generation strategy to make it appropriate for multi-week forecasting. The global coupled model includes high resolution atmospheric (N216 which is ~60 km in the mid-latitudes; and 85 levels in the vertical) and ocean (0.25° with 75 levels) models, as well as multi-layer land and sea-ice models.
Collection of various atmospheric reanalysis and observation data sets from local Australian and international sources such as NCEP-1, NCEP-2, ERA-40, ERA-40c and gridded observation data sets such as AWAP for weather and climate research. List of data sets: AWAP, CFSR, CMAP, COREv2, CRU, ERA40, ERA40c, GISS, GPCP, HADCRU, HOAPS, Hadisst, ISCCP, JRA25anl, JRA25fcst, Merra, NCEP2, NCEP2g25,NCEPg25, OAFLUX, and SOC
ERA-Interim is a global re-analysis produced by the European Centre for Medium-Range Weather Forecast (ECMWF). ERA-Interim set of global analysis describes the state of atmosphere, land and ocean-wave conditions from 1979 to the present date. It is widely used to build initial and boundary conditions in models and generally as climatology for climate studies. Our subset includes surface and 3-d variables on model levels, pressure levels, potential temperature and potential vorticity levels at 0.75X0.75 degrees of spatial resolution and also the ERA Interim Land version2 which uses a n improved land scheme. Some fields are also available at 1.5X1.5 degrees of spatial resolution. The data has a 6-hours time step and most fields are also available as synoptic monthly means and monthly means of daily means. The original data is in grib format, we convert it to NetCDF to make it more easily usable.
The broad geographical and temporal extent of this data makes together with the high number of represented fields makes this collection useful to a large number of earth science disciplines.

The ARC Centre of Excellence for Climate System Science (ARCCSS) Oceans Research Program has been working on a version of a 1/4 ocean model which is fully coupled into the ACCESS suite. This model is the product of a couple of years of work, lead by Paul Spence, Nic Hannah and Marshall Ward, with help from collaborators at GFDL and CSIRO. In June 2015 the first simulation was released, a 300 year, pre-industrial spin-up simulation. Other simulations will follow, so that the data can be used for studying the low-frequency variability and equilibrated mean state of the climate system at high ocean resolution.

The World Climate Research Programme (WCRP) is backing an international initiative called the COordinated Regional climate Downscaling EXperiment (CORDEX). The goal of the initiative is to provide regionally downscaled climate projections for most land regions of the globe, as a compliment to the global climate model projections performed within the fifth Coupled Model Intercomparison Project (CMIP5). CORDEX-AustralAsia includes data from both dynamical and statistical downscaling over Australia and the surrounding regions. The data covers the period from 1950-2100 and is designed for use within climate change impacts and adaptation studies. It is expected that many scientific publications will be produced using the data and will cite the dataset. CORDEX is an ongoing initiative that will continue to grow in both data contributions and use over the next several years. CORDEX data is being distributed through the Earth System Grid Framework (ESGF).

The Year of Tropical Convection is a joint project of the WWRP-THORPEX and the WCRP that combines high resolution analysis and forecast data with satellite data and a Tropical Cyclone Satellite Information System. YOTC is a year of coordinated observing, modeling and forecasting of organized tropical convection and its influences on predictability as a contribution to the United Nations Year of Planet Earth to complement the International Polar Year (IPY). This effort is intended to exploit the vast amounts of existing and emerging observations, the expanding computational resources and the development of new, high-resolution modeling frameworks, with the objective of advancing the characterization, diagnosis, modeling, parameterization and prediction of multi-scale convective/dynamic interactions, including the two-way interaction between tropical and extra-tropical weather/climate. This dataset is a of the re-analysis data produced by ECMWF for the YOTC.
This data includes all the available pressure levels analysis data and some of the surface data at the highest available resolution, 0.125X0.125 degrees. The data is available in its original format, grib, and it has been converted to NetCDF to facilitate its use.

This dataset is subset of OFES, OGCM (Ocean general Circulation Model) for the Earth Simulator. OFES is a fifty-year eddy-resolving simulation of the world ocean. The data cover from January 1980 to December 2010, the spatial extent is global with exclusions of the poles and resolution is 1/10 of degree. This high resolution allows a good representation of boundary currents and mesoscale eddies. High-resolution simulations, such as this, are not only useful to regional studies, but also to improve climate models, of which the ocean is an important component. Another important role is to provide climatology for areas where observations are sparse. As well as the simulation output data, this collection comes with software to perform Lagrangian trajectory simulations.

Community Atmosphere Biosphere Land Exchange (CABLE)
CABLE includes two subcollections:
This collection will comprise of critical global datasets, which are central to the evaluation/comparison of the CABLE land surface model against observational data. CABLE is part of the state-of-the-art Australian Community Climate Earth Systems Science ACCESS model. Land surface models need to be systematically evaluated against a wide range of observational or other benchmark data. This collection will enable the evaluation/comparison of various key CABLE parameters against remotely sensed estimated and other land surface models. This will in turn further enhance and inform future areas of CABLE model development. Evaluating CABLE against these data enables model deficiencies to be identified. This, in turn, enables model improvements to be made. CABLE is part of the ACCESS modelling system; improvements in CABLE therefore have national impact through enhancing the national capability in weather forecasting, climate projection and ultimately how climate change impacts on Australian physical and social systems This collection will avoid the duplicate download and re-gridding of these datasets by the CABLE community and hence enhance research collaboration. It will also ensure consistent updating of the data to allow researchers in Australia access to the latest versions of these data. CABLE trac wiki: https://trac.nci.org.au/trac/cable/wiki
