Weather Observing Program

The real-time observations from the automatic instruments at Truganina Weather are routinely provided to numerous third parties. We also take two manual observations each day, one in the morning and one in the evening, using both the automatic and manual instruments. We are a registered Storm Spotter for the ABOM and report incidents of severe weather caused by thunderstorms.

All significant disruptions to the normal observing program, not including problems experienced by third parties, are recorded in our PWS Operations Log.

Real-Time Observations

The real-time observations from the automatic instruments are submitted about every 5 minutes to these national and international weather exchange networks:

Standard Observing Practice

To be consistent with standard ABOM practice the meteorological day ends at 9.00 am, the exception is significant weather phenomena which ends at midnight:

Our evening observation is nominally taken at 6.00 pm and involves manually recording:

Note: The mercury-in-glass maximum thermometer was accidentally broken during 2021, thus ending the ongoing maximum temperature comparison at 9.00 am between the automatic and manual instruments. Both sets of instruments had previously given almost identical results.

Storm Spotter

Bureau of Meteorology Storm Spotter logoTruganina Weather is a registered volunteer Storm Spotter for the ABOM. The Storm Spotter Network is an important component of the Severe Thunderstorm Warning Service provided by the ABOM.

Storm Spotters provide "on-the-spot" reports if any of the following are observed:

Established in 1989, the Storm Spotter Network is based on similar networks implemented in Canada and the United States of America and accounts for a large proportion of severe weather reports received by the ABOM. The timely information helps forecasters to prepare and update severe weather warnings and also impacts on Australian research into severe thunderstorms by providing a better picture of the frequency and distribution of violent storms.

Community Rainfall Reader

Community Rainfall ReaderTruganina Weather is part of a network of more than 350 volunteer community rainfall readers that record daily rainfall for Melbourne Water.

Melbourne Water uses these volunteer records plus data from its own network of electronic rain gauges to help understand rainfall patterns across Melbourne, especially after heavy storms, to plan their works.

The combined data also helps Melbourne Water to plan responses to droughts and floods, and to make sure that rivers and creeks have enough water to support local wildlife.
