    The CSIRO versions of the BOM (Bureau of Meteorology Australia) ocean variables temperature and 20 degree isothermal temperature depth datasets for the region covering the Pacific to the Indian ocean. Individual monthly temperature and 20° isothermal temperature depth datasets have been concatenated into single contiguous netcdf files for the time period 1980-2008 with a spatial resolution of 1° x 2° at 14 levels from 0-500m. These have also been processed to include calculated Anomaly, Climatology, and Seasonal forms, approximately 8 files totaling 475.7 MB.

    The Australian Bureau Of Meteorology - Australian Gridded Datasets (BOM - Ausgrid) for the period from Jan 1961 until Dec 2000. The Ausgrid datasets are created by taking observational data from approximately 821 stations positioned across Australia and interpolating this to form a gridded dataset of the required variable for the required resolution. The CSIRO Archive contains the daily atmospheric variable Rainfall at .05° x .05° resolution for the region of South Eastern Queensland in Australia. The original Bureau of Meteorology Rainfall daily files for the whole Australia region have been processed to include only data for the South East Queensland region and have been concatenated into two forms. Single contiguous annual files (~14.8 MB), with 40 files totaling approximately 591 MB, and also as a single file (~591 MB also) for the whole period 1961-2000, in netcdf format.

    The Australian Bureau Of Meteorology (BOM) - Australian Daily Observed Rainfall datasets for the period from Jan 1910 until Aug 2005. The CSIRO archive contains the daily atmospheric variable Rainfall observational data from the 181 weather monitoring stations positioned across Australia. It is often refered to as High Quality data as it is not interpolated/reanalysed or gridded. There are 181 files with each having one stations data for the entire time period in ASCII format(approximately 1 MB) with the filename being the station ID. All stations files have been tarred into a single file for storage(approximately 160MB). There is also a reduced subset of this data available spanning the years from 1960-2000 available, 1 tarred file (containing 181 files) approximately 67 MB.

    The Australian Bureau Of Meteorology - Australian Gridded Datasets (BOM - Ausgrid) for the period from Jan 1960 until Dec 2000. The Ausgrid datasets are created by taking observational data from approximately 821 stations positioned across Australia and interpolating this to form a gridded dataset of the required variable for the required resolution. The CSIRO Archive contains the daily atmospheric variable Rainfall at .05° x .05° resolution for the region of Australia. Original zipped daily files have been concatenated into a single contiguous annual file (~800MB) in netcdf format, with 41 files totaling approximately 31.9 GB for the period 1960-2000.

    The Australian Bureau Of Meteorology - Australian Gridded Datasets (BOM - Ausgrid) for the period from Jan 2004 until the current day. The Ausgrid datasets are created by taking observational data from multiple stations positioned across Australia (821 Rainfall and 728 Temperature stations) and interpolating this to form a gridded dataset of the required variable for the required resolution. The CSIRO Archive contains the daily atmospheric variables Rainfall, Tmax and Tmin at .25° x .25° resolution for the region of Australia. Data has been stored in daily zipped files (ASCII format) with the following file naming convention [ausgridYYMMDD (YY=year, MM=month, DD=day)],with 365 files totaling approximately 15.90 MB per variable per year. This archive is updated on a daily basis.

    The CSIRO versions of the BOM (Bureau of Meteorology Australia) Australian Temperature datasets are a concatenation of the individual monthly Temperature datasets into a single contiguous netcdf file for the time period 1900-2007 with a spatial resolution of .25° x .25°. The variables tav(Average Temperature), tmax (Maximum Temperature), tmin (Minimum Temperature) & tdtr (Diurnal Temperature Range) are available for the whole of Australia and also as a subset for the Murray Darling Basin. These have also been processed to include calculated Anomaly, Climatology, and Seasonal datasets available for Australia. There are approximately 17 files for Temperature data totalling 921.32 MB.

    The CSIRO versions of the BOM (Bureau of Meteorology Australia) Australian Rainfall & Murray Darling Basin Inflow datasets are a concatenation of the individual monthly Rainfall & MDB Inflow data files into a single contiguous netcdf file for the time period 1900-2007 with a spatial resolution of .25° x .25°. These are available for the whole of Australia and also as subsets for the three regional areas of Murray Darling Basin, South East Queensland & Victoria (MDB, SEQ, VIC). The monthly Rainfall data has also been processed to include calculated Anomaly, Climatology and Seasonal forms of this dataset. There are approximately 13 files for Rainfall data totalling 424.9 MB and a single file for monthly MDB Inflow totalling 37 KB. An additional .xls file of "modelled data" was provided to the data centre in October 2014. All the data housed by CSIRO is for internal use only. Data access links via the BOM and MDBA are provided below.

    The Cape Grim Baseline Air Pollution Station facility, located at the North/West tip of Tasmania (40° 41'S, 144° 41'E), is funded and managed by the Australian Bureau of Meteorology, with the scientific program being jointly supervised with CSIRO Marine and Atmospheric Research. This archive contains 1000 litre air samples contained in stainless steel flasks collected at approximately 3 monthly intervals since 1978. The archive is housed at the Aspendale laboratory of CSIRO Marine and Atmospheric Research. The Cape Grim air archive is invaluable in determining the past atmospheric composition of a wide range of gases. For some of these gases, accurate and precise analytical methods have only recently evolved (for example HFCs and PFCs). The measurements are state-of-the-art in precision and accuracy. They are used to identify trace gas trends in the Southern Hemisphere, which in turn can be used to drive climate change models and identify processes that influence changes to the atmosphere.

    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.
