Variables included:

- Date: the local calendar date across which variables are summarised

- WS_DailyMean: daily mean wind speed (units = km/h)

- WD_DailyMean: direction of the daily mean (U,V) wind vector (units = degrees clockwise from north)

- PR_DailySum: total precipitation from midnight to midnight (units = mm)

- TM_DailyMean: daily mean temperature (units = degrees celcius)

- RH_DailyMean: daily mean relative humidity (units = percentage)

- U_DailyMean: mean daily east-west wind component (units = km/h)

- V_DailyMean: mean daily north-south wind component (units = km/h)

- WS_Midday: wind speed at midday (units = km/h)

- WD_Midday: wind direction at midday (units = degrees clockwise from north)

- TM_Midday: temperature at midday (units = degrees celcius)

- RH_Midday: relative humidity at midday (units = percentage)

- U_Midday: east-west wind component at midday (units = km/h)

- V_Midday: north-south wind component at midday (units = km/h)

- TS: The code "TS" (denoting thunderstorm) appeared in the METAR/SPECI records at some point in this day. These are based on meteorological observer reports from this site.

Notes:

1) These data are based on half-hourly summaries supplied by the Bureau of Meteorology.

2) When midday values were not available, the snapshot values were taken from the nearest time-point.

3) When preparing these summaries, the timing of midday and boundaries of each day were based on local time.

Data quality issues:

1) Precipitation was not available in this record before 1999-03-02.

2) The METAR/SPECI fields were not archived consistently prior to 1999-03-01.

The original data can be obtained from the Australian Bureau of Meteorology through their Climate Data services. See www.bom.gov.au for further information
