    Scanned copies of the Bureau of Meteorology Operational Synoptic Charts covering Australia. The charts are Mean Sea Level (MSL) charts with irregular upper air charts, this collection is on 3 CD's - for the months (April-October) between 1956 and 1959 - for the months (April-October) between 1960 and 1969 - random selection between 1956 and 1959.

    The CSIRO Dawn-2100 archive contains datasets for atmospheric, land and oceanographic variables for the approximate period 1850 - 2100 (dependent on model). These have been created through the concatenation of 20th century (20C3M) and other scenario (currently SRESA1B or SRESA2) data from a number of the 25 differant global climate models (GCM) from various countries. The SRESA2_va dataset contains the Northward wind variable for various GCM's and runs (multiple runs being averaged to a single file if existing) under the scenario SRESA2 emissions 2001 to 2100. 1 GCM model is available with data for variables being in 12 month, annual and 4 seasons(DJF, MAM,JJA,SON) format with 5 files totaling 1.40 GB as Netcdf files. Available for internal use and analysis by CSIRO staff on the HPSC cherax.

    The CSIRO archive of the Australian Bureau of Meteorology Global Analysis and Prediction (GASP) global gridded analysis datasets for the period from 1998 until present. The Global AnalysiS Prediction model uses spectral numerical analysis techniques to provide 6-hourly (00,06,12,18) variables at 60 levels from the surface to 10 hPa with a resolution of 1 deg (approximately 85 km horizontal resolution). Datasets have been tarred into single monthly archives with the following file following folder convention [ /YYYY/YYYYMM.tar (YY=year, MM=month)], with each monthly file being approximately 6-7 MB totaling 75.9 GB per year. Datasets are in netcdf format and are continuously updated.

    The National Centers for Environmental Prediction (NCEP) Aviation (AVN) global gridded analysis datasets for the period from Jan 2002 until the current day. The NCEP AVN gives 6 hourly Atmospheric variables at 26 levels with a resolution of 1 degree. It is a time limited model run produced to give global weather forecast predictions for other clients that rely on data being available at a fixed time, especially important for applications such as aviation. The AVN model was superceeded in October 2002 and is now known as the global forecast system (GFS)model, however as other software and systems rely on this folder naming convention {avnYYMM (YY=year, MM=month)} the newer GFS model data is still being saved with this older title. This archive is updated daily.

    The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) gridded analysis datasets for the period from Dec 2004 until the current day. The NCEP GFS is a global spectral data assimilation and forecast model system giving 6 hourly (00, 06, 12 and 18 UTC) atmospheric variables at 26 levels with a resolution of .5 degree. The GFS model superceeded the AVN in October 2002. Data is stored with the following folder convention {gfs2YYMM (YY=year, MM=month)}, this archive is updated on a daily basis.

    The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) final (FNL) gridded analysis datasets for the period from Jan 2000 until the current day. The NCEP GFS is a global spectral data assimilation and forecast model system giving 6 hourly (00, 06, 12 and 18 UTC) atmospheric variables at 26 levels with a resolution of .5 degree. The FNL version uses the same GFS model but the analysis is run at 3 hours past synoptic time instead (when more observational data is available), where a shorter (GDAS), 9-hr forecast is run. This 9-hr forecast is presumably of slightly better quality, as its analysis contains more observational information. The GFS model superceeded the AVN model in October 2002. Data is stored under a single folder(fnl) with 6 hourly files Zipped and Tar'd into a single monthly file with the naming convention {gfsYYMM (YY=year, MM=month)}. This archive is updated on a monthly basis.

    The Navy Operational Global Atmospheric Prediction System (NOGAPS) global gridded analysis datasets for the period from October 2006 until the current day. NOGAPS is the Department of Defense high resolution global numerical weather prediction system using a spectral model (GSM) with its development being a joint activity of the Naval Research Laboratory (NRL) and the Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC). NOGAPS data is available in 12 hourly (00 & 12 UTC) Atmospheric variables at 22 levels with a resolution of 1.25 deg. Data has been stored with the following folder convention [nogapsYYMM (YY=year, MM=month)], approximately 730 files per year totaling 5.64 GB with each 12 hr file being 8.2 MB. This archive is updated on a daily basis.

These have been created through the concatenation of 20th century (20C3M) and other scenario (currently SRESA1B or SRESA2) data from a number of the 25 differant global climate models (GCM) from various countries. The SRESA1B_ua dataset contains the Eastward wind variable for various GCM's and runs (multiple runs being averaged to a single file if existing) under the SRESA1B scenario (SRESA1B emissions 2001 to 2100, then constant GHG 720ppm). Data for variables is available in 12 month, annual and 4 seasons(DJF, MAM,JJA,SON) format with 15 files totaling 2.01 GB as Netcdf files. Available for internal use and analysis by CSIRO staff on the HPSC cherax.

    The CSIRO archive of the Tas Futures 2008 Regional Climate Model simulation datasets for the years 1961-2100. Created with the CSIRO CCAM (Cubic Conformal Amostpheric Model) RCM (Regional Climate Model) by dynamically downscaling the GFDL CM2.1 (Geophysical Fluid Dynamics Laboratory Global Climate Model 2.1) outputs to 60 km resolution (C64 Grid) with the main target area centered over Australasia. These runs have been completed using only bias corrected SST(Sea Surface Temperatures) and Sea Ice (No Atmospheric) forcings. 4X Daily atmospheric variables are available globally at 18 levels with .5º (60km) resolution on a C64 Grid. There are 1680 daily files in netcdf format, totaling approximately 2.47 TB. Regional climate data is also available for CCAM nested in other GCMS as part of this project. This dataset has also been further downscaled to 14km resolution for the Tasmania region.
