Quality Assurance Practices
This page outlines known instrument problems and the quality assurance practices adopted by Truganina Weather to ensure our data are of the highest quality possible.
Situations that affect the operation of our PWS and adversely impact on the availability or the quality of our data are recorded in our Operations Log.
Measured Elements
Mean Sea Level Pressure (MSLP)
The electronic MSLP data are routinely compared to the MSLP data from the nearby BoM AWS at Laverton (control data). This ongoing comparison enables adjustments to be applied as necessary to the electronic MSLP data displayed on the console. The comparison also enables adjustments to be made to the aneroid barometer.
Temperature
The electronic temperature data are routinely compared to the manual temperature data (control data). This ongoing comparison enables adjustments to be applied as necessary to the electronic temperature data in WUHU.
Our electronic temperature data, which are used in our real-time and daily reporting as well our monthly and long-term statistics, are routinely compared to the temperature data from a nearby BoM AWS for local consistency (see Performance Monitoring below).
Rainfall
The electronic rainfall data are routinely compared to the manual rain gauge data (control data). This ongoing comparison enables adjustments to be applied as necessary to the electronic rainfall data in WUHU.
Our manual rainfall data, which are used in our daily reporting as well as our monthly and long-term statistics, are routinely compared to the rainfall data from nearby electronic rain gauges in the BoM rainfall network for local consistency (see Performance Monitoring below).
Known Instrument Problems
- Our data-logging and display software (WUHU) occasionally registers erroneous rainfall following a reboot, and
- The 0.5 mm resolution of the electronic rain gauge is suitable for real-time reporting but is not suitable for daily reporting or monthly and long-term statistics.

Performance Monitoring
The daily rainfall and temperature data are routinely compared against the BoM AWS at Laverton. The daily rainfall is also routinely compared against the Melbourne Water rainfall and river level station on Skeleton Creek at Hoppers Crossing (Hoppers in the table below).
