24-hour probabilistic solar X-ray flare forecasts, issued hourly and 6 hourly [00, 06, 12 and 18UT]

The product contains probabilistic forecasts of X-ray solar flare activity expected to occur within a 24 hour period following the forecast issue time. The forecast probabilities pertain to the full visible solar disk and/or discrete active regions on the Sun. The probabilities relate to flaring at each of two magnitude levels: 1. M-class or greater flares (peak flux in 1-8 band exceeding 10-5 W/m2) [NOAA R-scale R-1 equivalent]; 2. X-class or greater flares (peak flux in 1-8 band exceed... more

ACORN-SAT Australia v2 ( ongoing ) : Australian Climate Observations Reference Network - Surface Air Temperature (1910 onwards)

The Australian Climate Observations Reference Network - Surface Air Temperature (ACORN-SAT) dataset v2 is comprised of a consistent - or homogeneous - daily temperature record since 1910, for up to 112 observation locations across Australia. This dataset aims to create a modern Australian temperature record, by selecting relevant sites which have a long data timespan, and maximise network coverage across the continent. The v2 dataset was initially released in December 2018, and supercedes ... more

Australian Gridded Solar Climatology Web Data Services

These datasets are long term averages of solar radiation at the surface over the Australian land mass. Applications of these data include solar energy, agriculture, building thermal design and water balance modelling. Climatologies are given for two radiation parameters: the global horizontal exposure, which is the total amount of solar energy falling on a horizontal surface over a time interval; and the direct normal exposure which is the total of the component of radiation from the sun?s di... more

Australian Hydrological Geospatial Fabric (AHGF) ( Geofabric ) Web Data Services

The AHGF : Australian Hydrological Geospatial Fabric (Geofabric) is a specialised Geographic Information System (GIS). It registers the spatial relationships between important hydrological features such as rivers, water bodies, aquifers and monitoring points. By detailing the spatial dimensions of these hydrofeatures and how they are connected, it is possible to analyse how water is stored, transported and used through the landscape.

Australian Landscape Water Balance simulated [ ALWB ] data - soil moisture, rainfall, evapotranspiration, deep drainage and runoff estimates [ 1911 onwards ] {DRAFT stopgap metadata}

The datasets presented on the Australian Landscape Water Balance portal (and by request) provide nationally consistent landscape water balance estimates daily, at high resolution (5 km) across Australia. The estimates are of water fluxes, soil moisture and groundwaterstores in the Australian landscape, and are based on a model that simulates the flow of water through the land portion of the landscape?through the vegetation and soil?and then out again through evapotranspiration, runoff or dee... more

Australia Ocean 3D Bluelink Forecast Data Sample (2017)

This is a three-dimensional forecast of ocean state from the sea surface to the deep ocean. The OceanMAPS model is a Bureau of Meteorology operational global ocean forecast system with 0.1 degree horizontal resolution, and variable vertical resolution. This dataset captures a one-year period and is provided to support anyone wanting to better understand the model, or how to work with this data.

CDO ( Climate Data Online )- Temperature, Rainfall, and Solar Exposure - Daily and Monthly Values per site ( 1832 onwards )

Climate Data Online offers temperature, rainfall and solar exposure values, per day, and per month for each station, for all years that a Station has been operating and measuring that variable. Data is from both closed and open stations. Data timespans vary across stations. The earliest data is for Parramatta, commencing 1832. Data values are typically incorporated into CDO within 24 hours of the value being recorded, but QC of the data can take some time. The data's QC-status is indicated... more

Climate statistics - per site, Australasia (1834 onwards) : temperature, rainfall, wind, evaporation, sunshine, humidity, cloud and pressure

For each station, an extended list of climate statistics is provided. Data includes various statitics related to air temperature , dew-point temperature , wet-bulb temperature , ground temperature , rainfall , wind , sunshine hours , solar exposure , cloud cover , evaporation and relative humidity. Data timespans vary depending on each site's commencement, and when that data parameter was first collected at the site. Data covers all years that a site has been measuring that data paramete... more

Cloud (9am & 3pm) : Mean monthly, seasonal and annual cloud gridded data (base climatological dataset, 1976-2005), Australia

Mean monthly, seasonal and annual 9am and 3pm cloud grids, showing the cloud values across Australia in the form of two dimensional array data. The mean data are based on the standard 30-year period 1976-2005. Total cloud amount data is recorded at a network of weather stations across Australia. The total cloud amount is measured visually by estimating the fraction (in eighths or oktas) of the dome of the sky covered by clouds. A completely clear sky is recorded as zero okta, while a tota... more

Daily weather observations - per site, Australasia (2003 onwards) : temperature, rainfall, wind, evaporation, sunshine, humidity, cloud and pressure

Daily Weather Observations provides observations, for approximately 840 locations, of a number of weather elements each day for a month. Included are daily minimum and maximum temperature, rainfall, strongest wind gust, evaporation, and sunshine, together with values at 9am and 3pm of temperature, humidity, wind, cloud and pressure. Not all stations in the Bureau of Meteorology's network observe all these elements. Therefore, where appropriate, observations from a number of contiguous station... more
