The CSIRO archive of observed atmospheric CO2 concentrations at the Aspendale CSIRO Marine and Atmospheric Research division measured with the CSIRO developed LOFLO Mk2 instrument. LOFLO is an analysis system built around a commercial LI-COR 6251 optical bench which utilizes NDIR (non-dispersive infrared) gas analysis technology to measure CO2 concentrations in sample air. Consuming smaller volumes of calibration gases (approx. 15ml/min) and requiring much less operator intervention, LOFLO measurements have significantly less bias than traditional NDIR measurement techniques. Measurements using LOFLO first began at Cape Grim in May 2000 and has since been expanded to other global stations with the newer improved LOFLO Mk2. Stations using LOFLO include Cape Grim, Maquarie Island, Otways Basin and Aspendale. CO2 measurements are available from the Aspendale Air Pollution Station for the period 24/4/08 until present, with logged data available as yearly ascii text files in hourly averaged and minutely averaged periods for CO2 concentration, standard deviation, max & min values as well as a baseline flag. Typically file size is approximately 500 KB and 12 MB for an hourly averaged and minutely averaged year of data respectively.

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 Climate Prediction Centers (CPC) Merged Analysis of Precipitation (CMAP) dataset uses a technique which produces pentad and monthly analysis of global precipitation in which observations from raingauges are merged with precipitation estimates from several satellite-based algorithms (infrared and microwave). The CSIRO version of this dataset is a concatenation of the individual monthly data files into a single contiguous netcdf file for the two sepearate time periods of 1979-2006 and 1980-1999 with a spatial resolution of 2.5° x 2.5°. The 1980-1999 version of the dataset has also been processed to include calculated Climatology and Seasonal forms of this dataset. There are approximately 4 files totaling 27.1 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 CSIRO archive of observed atmospheric CO2 concentrations at the Otway Basin Naylor Field (30km WNW of Peterborough) carbon-dioxide geo-sequestration site, measured with the CSIRO developed LOFLO Mk2 instrument. This study (the first of its kind in Australia) by the Cooperative Research Center for Greenhouse Gas Technologies (CO2CRC) is to monitor the trial geo-sequestration of CO2 into the depleted gas field (Naylor Field) and to observe the environmental effects to determine the viability and effectiveness of CO2 geo-sequestration. LOFLO is an analysis system built around a commercial LI-COR 6251 optical bench which utilizes NDIR (non-dispersive infrared) gas analysis technology to measure CO2 concentrations in sample air. Consuming smaller volumes of calibration gases (approx. 15ml/min) and requiring much less operator intervention, LOFLO measurements have significantly less bias than traditional NDIR measurement techniques.Measurements using LOFLO first began at Cape Grim in May 2000 and has since been expanded to other global stations with the newer improved LOFLO Mk2. Stations using LOFLO include Cape Grim, Maquarie Island, Otways Basin and Aspendale. CO2 measurements are available from the Otways Basin geosequestration site for the period 12/1/07 until present, with logged data available as yearly ascii text files in hourly averaged and minutely averaged periods for CO2 concentration, standard deviation, max & min values as well as a baseline flag. Typically file size is approximately 500 KB and 12 MB for an hourly averaged and minutely averaged year of data respectively.

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.

This product represents the predicted spatial patterns of species abundance, species richness and species evenness of demersal fish communities in the SEMR. It provides a description of the structure rather than the composition (i.e. specific species) of these assemblages. Structure equates to total species abundance (the total number of individuals), species richness (the total number of species) and species evenness (relative proportions of species). The product can also be used to identify areas in the SEMR that are predicted to have unique combinations of species richness and evenness. This allows managers to identify areas that are predicted to have common or rare types of community structure.

This product (i.e. Access data base) contains data (longitudes, latitude and biodiversity attribute variables) that describes the predicted spatial patterns of biodiversity categories based on species richness and evenness of demersal fish in the EMR. This product provides predictions for total species abundance, species richness and species evenness and estimates of uncertainty for demersal fish. The predicted patterns are represented as point data arranged on a 0.1 degree grid (~ 1.2 km2) covering depths 50-900 metres in the EMR from 24oS to 34oS

The CSIRO Bayside Air Quality Station datasets contain measurements of important urban air pollutants for the period of June 2004 to the present day measured in the atmosphere at the CSIRO Aspendale measuring station. There are variables for both chemical (gases such as carbon monoxide(CO), nitrogen oxides (NO, NO2, NOx), sulfur dioxide(SO2) & ozone(O3)) and physical properties (particulate mass measurements: size<10µm(Pm10), size<2.5µm(Pm2.5), size<100nm(UFP)). Variable data is logged on a minutely basis and is available in daily-average annual and hourly-average monthly excel spreadsheet formats. The Bayside Air Quality Station is located at CSIRO Marine and Atmospheric Research (CMAR) Aspendale, Victoria (38° 01' 41" South, 145° 01' 48" East)
