The Australian Bureau Of Meteorology - Australian Gridded Intensity, Frequency, Duration Datasets (BOM - IFD) for a 100 year return interval. IFD datasets contain rainfall statistics, with the CSIRO Archive having data for 2, 24 & 72 hour periods at .05° resolution for the South East Australia region covering New South Wales and Victoria. IFD datasets are commonly used in Climate change studies, for design and risk assessment of dams and bridges, design of roof and stormwater drainage systems, flood plain management, soil conservation studies and to express the "severity" of a single rainfall event (in terms of its rarity). The process of estimating IFDs, known as frequency analysis, is an important part of hydrological design procedures. An analysis of rainfall data from a single station is often unreliable; not temporally or spatially consistent; and should generally not be used for design purposes. Instead a set of accurate, consistent IFD data was derived for the whole of Australia by the Bureau of Meteorology as part of the revision of Australian Rainfall and Runoff with the Institute of Engineers Australia(1987). INTENSITY is the rainfall rate (in mm per hour), FREQUENCY is how often a type of rainfall event will occur and DURATION is the period of time over which the rain is measured. There are 3 files covering the 2, 24, 72 hr periods (each ~1.03MB) in Ascii Arcg format totaling approximately 3.11 MB.

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.

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 NCEP/NCAR (National Center for Environmental Protection/National Center for Atmospheric Research) Re-analysis 1 project (NCEP R-1) is an analysis/forecast system to perform data assimilation using past data from 1948 to the present. In 1998 NCEP/DOE (National Center for Environmental Protection/Department of Energy) partnered to produce the Re-analysis 2 project (NCEP R-2) to address model and human errors identified in the old reanalysis R-1 model. Several error fixes were introduced in going from R-1 to R-2, most importantly the Southern Hemisphere bogus data problem (1979-1992) that rendered R-1 almost unusable for Southern Hemisphere extratropical investigations for the affected years. The oceanic albedo was too high by a factor of about two for the entire reanalysis period, may have affected the Southern more than the Northern Hemisphere because of the greater proportion of ocean surface. Other errors were found with the snow-cover analysis, discontinuities in the relative humidity and cloudiness relationship table and a snow-melt term and the presence of an undesired “spectral snow” feature. Output of the NCEP R-1 product continues to be released to the present day, however, R-2 has only been performed for the years of 1979-2002 for detailed evaluation. These datasets can be found on cherax in the subdirectories for R1 (other gauss, pressure, spectral, surface, surface gauss and tropopause), which match the names used by NCEP in their anonymous server. For R-2 other gauss and surface gauss have been merged into gaussian grid, and tropopause data do not exist at this point in time. All variables that are a function of time are resolved every 6 hours (0h, 6h, 12h and 18h UTC), and a complete year of data is written to a single file (either 1460 or 1464 times depending on whether the particular year is a leap year). The pressure data are on a 2.5 by 2.5 degree horizontal grid ( 144 × 73 regular grid points) for each of the 17 pressure levels2. The surface and tropopause data are also on a 2.5 by 2.5 degree horizontal grid (144 × 73 regular grid points). The surface gauss and other gauss (or gaussian grid in R-2) data have an approximate 1.8 by 1.8 degree horizontal grid (192 × 94 Gaussian grid points or approximately 200 km horizontal spacing). The spectral data is in coefficient form, there are 4032 for the T62 model resolution. Seasonal and monthly climatologies are available for the period 1948-2003 for the R-1 data and 1979-2001 for the R-2 data. For every variable there are four types of average netCDF files that are referred to as long-term monthly (lm), longterm seasonal (ls), year-by-year monthly (ym) and year-by-year seasonal (ys). The four seasons are referred to with the abbreviations DJF (December, January and February average), MAM (March, April and May average), JJA (June, July and August average) and SON (September, October and November average).

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_pr dataset contains the Precipitation flux 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. These variables have also been further analysed to give monthly, seasonal and annual trend data, calculated from a monthly timeseries referenced to the area-weighted mean global warming values. 19 GCM models are available with data for variables being in 12 month, annual and 4 seasons(DJF, MAM,JJA,SON) format with 37 files totaling 5.22 GB as Netcdf files. Available for internal use and analysis by CSIRO staff on the HPSC cherax.
