Thanks for posting your blind belief in JM's - Jennifer Marohasy's - interpretation of what is actually done. Pity you didn't provide the BoM's actual statement.
Here, below, is what the BoM
actually said.
Again, you and Marohasy distort and mislead. The BoM data has the same time constant and characteristics as a mercury thermometer and is consistent with international practice.
This and the other thread are entirely based on fabrications and lies by you and Marohasy.
And you have the gall, the bigoted arrogance and stupidity, to call others "dumb" and "retard".

How does the Bureau measure and record temperature?
The Bureau measures air temperature using an electronic sensor (a platinum resistance thermometer) placed within a Stevenson Screen, and temperature is measured every second.
The air temperature fluctuates frequently on the scale of seconds. By using a sensor which has a longer response time than the fluctuations of the air temperature, the sensor “averages” these fluctuations.
Both the mercury-in-glass thermometers, and the electronic sensors, are housed within a Stevenson Screen. The time taken for air to be exchanged from the outside environment to within the screen provides a further time integration for the measurement of the ambient air temperature.
The response time of the sensor used in the Bureau AWSs is as long or longer than the changes in the temperature of the air it is measuring.
This means that each one second temperature value is not an instantaneous measurement of the air temperature but an average of the previous 40 to 80 seconds. This process is comparable to the observation process of an observer using a "mercury-in-glass" thermometer.
Are these methods consistent with international best practice?
The Bureau's procedures comply with the World Meteorological Organization's Guide to Meteorological Instruments and Methods of Observation (the CIMO Guide) WMO-No. 8 (2014 edition). The guide is available here. The guide recommends that temperatures be integrated over time to smooth out rapid fluctuations. There is more than one method of achieving this. The WMO guidelines do not prescribe which method to take. In its automatic weather stations the Bureau achieves this by using platinum resistance thermometers. These are comparable to mercury in glass thermometers.
