Summary

Hobart (Mt Koonya) radar is a new state-of-the-art weather radar (C-band Doppler radar). The new radar has a higher resolution than the previous radar - at Hobart Airport - and its Doppler capability allows the display of wind flows associated with weather systems as well as rainfall intensity on the Bureau's website. This information helps forecasters and the community see, in greater detail, upcoming weather - including severe weather such as thunderstorms and strong winds.

The new radar will also help improve forecasts for the region by providing forecasters with additional information on rainfall from thunderstorms to cold fronts that can move towards the populated southeast from the west at any time of the year.

These improvements include better:

  • continuous 24/7 weather radar coverage for southern Tasmania via the Bureau's website
  • better estimates of rainfall rates for use in flood warnings
  • detection of clear air boundaries which are vital for groups like bushfire management agencies and the aviation industry.

The radar location is on the Tasman Peninsula just on 46km east-south-east of Hobart. The radar site is some 478m above sea level with the tower an additional 36.6m above ground level (the tallest radar tower in the country).

The new radar was installed as part of the Strategic Radar Enhancement Project (SREP). The SREP initiative will deliver four new radars over the next few years to close significant gaps in the existing weather radar coverage for Australia, and develop the underlying science to enhance the capability in warnings and forecasts.
