BOM IFD - Bureau Of Meteorology, South East Australia (NSW,VIC) Gridded Intensity, Frequency, Duration datasets (.05º 100 year return interval)
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.
