# I believe these are the official period of measurement for Min/Max data by the BoM in Australia.

FURTHER (Till 31/01/2012)

 

 

 

 

 

~ Humidity over 97% equals 100%, under 10% equals 5%

 

 

~ Wind gusts are unable to be measured under 4.3km/h

 

 

~ Heat Index is not calculated when the air temperature falls below 20C, it equals the air temperature.

~ Air pressure is taken from station level (approx 8m ASL). Add 1hPa for sea level pressure.

 

 

FURTHER (From 01/02/2012)

 

 

 

 

 

~ Humidity limit values are no longer restricted

 

 

~ Wind gusts are unable to be measured under 0.5km/h accurately, thus are ignored

 

 

~ Heat Index is not calculated when the air temperature falls below 20C, it equals the air temperature.

~ Air pressure is taken from station level (approx 8m ASL). Add 1hPa for sea level pressure.

Current Monthly Report - Data averaged for the month so far. Where extreme average records are mentioned,

these are calculated on the data received so far. Records are officially recognised only after an official monthly

report has been released.
