Climate service announcements
Weekly Tropical Climate Note web address change
Scheduled release date: 15 September 2015
The web address of the Weekly Tropical Climate Note will be changing to www.bom.gov.au/tropical-note/. The old web address will be discontinued. Please update your bookmarks and links.
Changes to the Cooperative Observer Network
Scheduled update: 1 August 2015
From 1 August 2015 a number of manual observation sites will record a single, daily observation and will no longer have 3 pm observations. The majority of sites are unaffected by this change.
The Bureau's observations network includes a broad range of meteorological observations equipment to meet the needs of its forecasting and severe weather warning services, and provides data for the National Climate Record.
The Bureau continually assesses its network of meteorological observations to ensure the most effective and cost efficient network is in operation. As the availability of automated observations has increased, the number of manual observations has decreased.
In some cases data from nearby Automatic Weather Stations may be accessed on the Bureau's website as an alternative.
Northern Rainfall Onset outlook
Scheduled release date: 25 June 2015
The Northern Rainfall Onset outlook is a seasonal outlook service for tropical Australia. It includes maps, graphs and a description of the chance of the northern rainfall onset being earlier or later than average across the region.
The Northern Rainfall Onset outlook will be linked from the Climate homepage, and Climate outlooks
Weekly Rainfall Update web address change
Scheduled release date: 31 March 2015
The web address and format of the Weekly Rainfall Update will be changing. Content will remain consistent, however links to old state rainfall tables will be replaced.
The Weekly Rainfall Update is linked from the Climate homepage, Rainfall deficiencies, Reports and summaries and the climate RSS feed.
Seasonal climate outlook update
Scheduled release date: 22 May 2013
The Bureau of Meteorology is updating the model it uses for the monthly Seasonal climate outlook
The 3-month outlooks will be based on a dynamical model, which uses the physics of the atmosphere, oceans, land and ice interactions to calculate the probability of above (or below) normal rainfall and temperature. Previously, outlooks were based on a statistical model, which uses history as a guide to the next season's rainfall and temperature.
Climate change and variability update
Scheduled release date: 30 April 2013
The updated Climate change and variability page integrates related information and adds a 'Climate updates' feature section.
ACORN-SAT data has replaced the previous temperature dataset in Australian trend map and timeseries applications.
Climate model summary update
Scheduled release date: 18 February 2013
An updated and enhanced Model summary page has replaced Model outlooks of ENSO conditions.
Please update your bookmarks and links.
The Model summary page has added graphs, Indian Ocean Dipole and more model background information.
New one minute solar data service
Scheduled release date: 29 August 2012
One minute solar data
A new service has been externally funded to provide web access to one minute resolution solar data from the Bureau's ground solar network. All available data are online, accessed one station-month at a time. Data are free but an automated registered user approach has been implemented to assist service management.
A companion product (IDCJAD0114) is also available (at cost recovery charges) which provides all one minute solar data and associated one minute AWS weather data (when available) on a USB drive.
Weather station directory update
Scheduled release date: 13 August 2012
The updated Weather station directory is now dynamic, enabling searches for climate data stations based around a town, geographic location, or Bureau station number. Half hourly and one minute data are now included. The resultant station list can be included in a form to request data from Climate data services. Links are provided to data freely available online.
New Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) dataset
Scheduled release date: 23 March 2012
The Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) dataset has been developed for monitoring climate variability and change in Australia.
The ACORN-SAT page includes dataset background information and links to the station catalogue and data.
Maps - recent conditions update
Scheduled release date: 7 December 2011
Monthly rainfall data quality control changes
Scheduled release date: 11 October 2011
Climate Data Online monthly rainfall information is being updated. A recent data review has resulted in changes to the classification of quality controlled monthly-total rainfall data. Around 500,000 records (5.5% of total records) will have their status changed to ‘not quality controlled’. The total precipitation value should remain unchanged. These records are pre-2000, with greater than half pre-1950. Their status was down-graded because they lacked historical detail.
During the review process a small quantity of daily rainfall data were recovered enabling updating and additional monthly totals to be calculated.
New data services portal
Scheduled release date: 5 September 2011
The new Data services portal introduces integrated data services information and tools to help streamline custom data requests and enquiries.
Daily rainfall, temperature, solar exposure: all years of data available in one file
Scheduled release date: 28 April2011
From Climate data online, all years of daily rainfall, temperature and solar exposure data can now be downloaded in a single file, for each weather station. This history file is linked as 'All years of data' in the top right corner of the data table and graph pages.
Solar exposure data: daily and monthly station data now available from Climate data online
Scheduled release date: 14 December 2010
From Climate data online, daily and monthly solar exposure tables, graphs and data are now available.
You can use solar exposure data to estimate the amount of solar energy available.
New climate and weather extremes service
Scheduled release date: 7 December 2010
Australian climate and weather extremes provides information about extremes of temperature and rainfall. The highest and lowest maximum and minimum temperatures and highest daily rainfall are presented as tables, graphs and maps for each state, the Northern Territory and Australia.
