The transition to polarimetric (dual-polarised) radars began in 2017 with the upgrade of 4 Meteor 1500 radars located in Melbourne, Brisbane, Adelaide, and Sydney. [7] The network has further been enhanced through the installation of 8 new polarimetric Meteor 735 radars across WA, [8] NSW [9] & Victoria, [10] and two polarimetric WRM200 radars [11] manufactured by Vaisala, one to replace the ...
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the state meteorological services that existed before then. [3]
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The Bureau of Meteorology noted that "Kalgoorlie Doppler Radar image at 0725 UTC (1525 AWST) showed a pixel which had an inbound velocity of around 110 km/h at a height of ~487 metres above the ground (aliased: 22.5 m/s outbound)" in the tornado record for this event.

Weatherzone, known before 9 August 2010 as The Weather Company and still trading under this name, is the main provider of value-added meteorological services in Australia. [ citation needed ] Their main business lines are services to energy, utilities and mining companies.
For example, a radar mounted on top of a 10 m (33 ft) mast has a range to the horizon of about 13 kilometres (8.1 mi), considering atmospheric refraction effects. If the target is above the surface, this range will be increased accordingly, so a target 10 m (33 ft) high can be detected by the same radar at 26 km (16 mi).
The Jindalee Operational Radar Network (JORN) is an over-the-horizon radar (OHR) network operated by the Royal Australian Air Force (RAAF) that can monitor air and sea movements across 37,000 square kilometres (14,000 sq mi).
Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range of 128 km (80 mi), for detecting velocity pattern (Doppler effect), and an extra long range up to 240 km (150 mi) at low elevation angle but strongly folded or aliased (where the maximum unambiguous velocity interval (±Vmax ...
