    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.

    The National Centers for Environmental Prediction (NCEP) Aviation (AVN) global gridded analysis datasets for the period from Jan 2002 until the current day. The NCEP AVN gives 6 hourly Atmospheric variables at 26 levels with a resolution of 1 degree. It is a time limited model run produced to give global weather forecast predictions for other clients that rely on data being available at a fixed time, especially important for applications such as aviation. The AVN model was superceeded in October 2002 and is now known as the global forecast system (GFS)model, however as other software and systems rely on this folder naming convention {avnYYMM (YY=year, MM=month)} the newer GFS model data is still being saved with this older title. This archive is updated daily.

    The Canadian Metrology Center (CMC) gridded datasets containing wind, temperature, specific humidity and other flux's and ground level variables for the period from Jan 2006 until the current day. The CMC gridded dataset consists of 12 hourly (00, 12 UTC) Atmospheric variables at 28 levels with a resolution of 1 deg. Data has been stored with the following folder convention [cmcYYMM (YY=year, MM=month)], approximately 730 files totaling 28.10 GB per year, with each 12 hr file being 38.5 MB. This archive is updated on a daily basis.

    The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) gridded analysis datasets for the period from Dec 2004 until the current day. The NCEP GFS is a global spectral data assimilation and forecast model system giving 6 hourly (00, 06, 12 and 18 UTC) atmospheric variables at 26 levels with a resolution of .5 degree. The GFS model superceeded the AVN in October 2002. Data is stored with the following folder convention {gfs2YYMM (YY=year, MM=month)}, this archive is updated on a daily basis.

    The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) final (FNL) gridded analysis datasets for the period from Jan 2000 until the current day. The NCEP GFS is a global spectral data assimilation and forecast model system giving 6 hourly (00, 06, 12 and 18 UTC) atmospheric variables at 26 levels with a resolution of .5 degree. The FNL version uses the same GFS model but the analysis is run at 3 hours past synoptic time instead (when more observational data is available), where a shorter (GDAS), 9-hr forecast is run. This 9-hr forecast is presumably of slightly better quality, as its analysis contains more observational information. The GFS model superceeded the AVN model in October 2002. Data is stored under a single folder(fnl) with 6 hourly files Zipped and Tar'd into a single monthly file with the naming convention {gfsYYMM (YY=year, MM=month)}. This archive is updated on a monthly basis.

    The Navy Operational Global Atmospheric Prediction System (NOGAPS) global gridded analysis datasets for the period from October 2006 until the current day. NOGAPS is the Department of Defense high resolution global numerical weather prediction system using a spectral model (GSM) with its development being a joint activity of the Naval Research Laboratory (NRL) and the Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC). NOGAPS data is available in 12 hourly (00 & 12 UTC) Atmospheric variables at 22 levels with a resolution of 1.25 deg. Data has been stored with the following folder convention [nogapsYYMM (YY=year, MM=month)], approximately 730 files per year totaling 5.64 GB with each 12 hr file being 8.2 MB. This archive is updated on a daily basis.

    The CSIRO archive of Cape Grim Baseline Air Pollution Station - Hourly Atmospheric Meteorology datasets. 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. The role of the station has been to observe global air quality through the measurements of atmospheric pollution such as carbon dioxide, ozone, halocarbons, oxides of nitrogen, particulates, precipitation chemistry as well as to monitor other parameters such as solar radiation and meteorological variables. This archive contains hourly measurements of Atmospheric Wind speed and direction at 10 & 50m heights, temperature, humidity, rainfall, atmospheric pressure, number of baseline minutes for the hour, CN counts and carbon dioxide concentrations for the period from Jan 1976 until the present. Variable data is available as both an hourly averaged annual file or as a single (all years concatenated) file in either in Ascii (.dat) or binary (.bin) file format, including both Australian Eastern Standard Time (AEST) time and Co-ordinated Universal Time (UTC=AEST-10hr, also called GMT) time and date formats within each file.

  • This record describes the BASTA radar and Radiosonde products by Protat et al. (2020) from observations made in the Northern Territory northwest region. A shipborne 95 GHz Doppler cloud radar mounted on a stabilized platform was used to retrieve vertical profiles of three-dimensional (3D) winds by sequentially pointing the stabilized platform in different directions. The resulting dataset consists of the processed BASTA 3D winds (the subject of the paper), and the radiosonde dataset, which is used for validation. For more details please refer to the cited article (download link provided below): Protat, A. and I. McRobert (2020): Three-dimensional wind profiles using a stabilized shipborne cloud radar in wind profiler mode. Atmos. Meas. Tech., 13, 1–12. https://doi.org/10.5194/amt-13-1-2020.

  • This record describes the upper meteorological data collected with combined dual sensing by Windsond and Anasphere tethersonde on the RV Investigator Voyages from 2016 onwards. Parameters measured: pressure, temperature, relative humidity directly, then derived values for height, dew point, vapour pressure, mixing ratio and potential temperature. This data will also be available at the Australian Ocean Data Network (portal.aodn.org.au) and the World Data Centre for Greenhouse Gases (https://ds.data.jma.go.jp/gmd/wdcgg/). Further information can be found in the data and documentation links below.

  • This record describes Underway (UWY) data collected from the Marine National Facility RV Investigator Event voyage IN2014_E03. This is the first trial voyage for the RV Investigator departing Hobart on the 11th November and returning to Hobart on the 17th November 2014. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. The UWY data from this trial voyage was assessed and will not be processed as the quality is too variable to make it feasible/useful. The unprocessed UWY data is part of the EOV archive and will not be released.
