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 ABOM 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, plus our monthly and long-term statistics, are routinely compared to the temperature data from a nearby ABOM 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 plus our monthly and long-term statistics, are routinely compared to the rainfall data from nearby rain gauges in the ABOM rainfall network for local consistency (see Performance Monitoring below).

Performance Monitoring

Daily monitoring of the primary elements (rainfall, maximum temperature and minimum temperature) is achieved by comparing the data from Truganina Weather against the ABOM AWS at Laverton (ABOM ID = 087031 in the table below). Our daily rainfall is also compared to the Melbourne Water rainfall and river level station on Skeleton Creek at Hoppers Crossing (ABOM ID = 587049 in the table below).

087031 = ABOM AWS at Laverton, 587049 = Melbourne Water rain gauge at Hoppers Crossing.

This table is normally updated each day after the evening manual observation
