    These wind statistics data are collected continuously at the Tasmanian Earth Resources Satellite Station (TERSS) facility on Droughty Hill near Hobart on Tasmania's south east coast. Data collection began in September 1995 and continued to Dec 2011. Instrument Details: Location: latitude -42.9256, longitude 147.4206, ground elevation 150m, instrument 7 metres above ground. Manufacturer: R.M. Young Company. Traverse City, Michigan 49686 U.S.A. 616-946-3980 (http://www.youngusa.com) Model: Wind Monitor, model 05103V (See link to brochure). Data: Each line of data gives values reduced from samples collected every second over the preceding 10 minutes. Parameters include: Date; Time (UTC); Mean wind speed; Minimum wind speed; Maximum wind speed; Mean direction; Standard deviation of the previous 10 1-minute direction averages; Vector averaged wind speed; Vector averaged wind direction; Vector averaged "stress" in (m/s)**2; Vector averaged stress direction. The code that takes the one second readings and produces the 10 minute averages in the data files is available via the documentation links section). NOTE: This data is collected in order to assist in the daily management of the satellite dish. The instrument is located at a site to suit this particular purpose, not at a location that would provide the best statistics for other purposes.

    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.

    Wind-induced currents are among the strongest currents in the oceanic surface layer. Winds drive ocean currents by transferring momentum to this layer. The important quantity in this process is the wind stress, which is a quadratic function of wind speed. The data used in this project were produced by the NCEP/NCAR reanalysis project. NCEP and NCAR are cooperating in a project to produce a 40-year record of global analyses of atmospheric fields in support of the needs of the research and climate monitoring communities. The wind-stress dataset covers the period 1965 to 1997 and contains the following fields from which the velocity vector (speed and direction) were calculated: .zonal wind stress .meridional wind stress

    Maps showing quarterly means of wind curl on Australia's oceans from interpreted basedata supplied by the National Centers for Environmental Prediction (NCEP) Re-analysis Project, 1976 to 1998 inclusive. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

    The SODA (Simple Oceanographic Data Assimilation) datasets are global ocean reanalysis datasets created by assimilating timely temperature and salinity observational data into an eddy permitting forecast model based on the Parallel Ocean Program POP1.3 model forced with ERA40 winds. SODA was created to reconstruct historical ocean climate variability on space and timescales similar to those captured by the atmospheric reanalysis projects at NCEP. The CSIRO version of the ENACT dataset is a concatenation of the individual monthly variables into single netcdf files for the time period 1958-2001 with a spatial resolution of .5° x .5° at 40 levels. It has also been processed to include calculated anomaly and climatological forms of this data. There are 3 models available: Ver1.2: Monthly-9 files 80.4GB, Anomaly-9 files 77.3GB, Climatology-9 files 1.88GB Ver1.4.2: Monthly-7 files 76.1GB, Anomaly-8 files 78.0GB, Climatology-7 files 3.5GB Ver2.0.2: Monthly-16 files 152.0GB, Anomaly-16 files 156.0GB, Climatology-16 files 3.5GB

    The European Centers for Medium range Weather Forecasts (EMCW) Ocean Re-Analysis System 3(ORA-S3) datasets, created by the synthesis of surface and subsurface ocean observations (temperature, salinity, altimeter derived sea-level anomalies) , surface fluxes from atmospheric analysis and reanalysis, and a general circulation ocean model(HOPE). ORA-S3 was created and is used to provide initial conditions for coupled model forecasts as well as seasonal & decadal forecasting predictions within the ENSEMBLES project. The CSIRO version of the ORA-S3 dataset is a concatenation of the individual monthly variables into single netcdf files for the time period 1959-2006 at 256 lat & 195 Lon positions with 29 Levels. It has also been processed to include calculated Anomaly, Climatological and Seasonal forms of this data. There are 10 Monthly files 13.0GB, 10 Anomaly files 13.0GB, 10 Climatology files 557MB, and 10 Seasonal files 9.81GB.

    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.

    On the FRV Southern Surveyor cruise SS3/90, 108 stations throughout the Gulf of Carpentaria were sampled for sea temperature, salinity, water depth, and sediment grain size. Data was also collected from the 1989-1990 "Jacqueline D" cruises and from commercial trawlers. Relevant rainfall, wind and temperature data were obtained from the Meteorological Bureau.
