Daily weather observations from multiple locations around Australia, obtained from the Australian Commonwealth Bureau of Meteorology and processed to create this realtively large sample dataset for illustrating analytics, data mining, and data science using R and Rattle.
The data has been processed to provide a target variable
RainTomorrow (whether there is rain on the following day -
No/Yes) and a risk variable RISK_MM (how much rain recorded in
millimeters). Various transformations are performed on the data.
The weatherAUS dataset is regularly updated an updates of this
package usually correspond to updates to this dataset. The data is
updated from the Bureau of Meteorology web site.
The locationsAUS dataset records the location of each weather
station.
The source dataset comes from the Australian Commonwealth Bureau of Meteorology. The Bureau provided permission to use the data with the Bureau of Meteorology acknowledged as the source of the data, as per email from Cathy Toby (C.Toby@bom.gov.au) of the Climate Information Services of the National CLimate Centre, 17 Dec 2008.
A CSV version of this dataset is available as https://rattle.togaware.com/weatherAUS.csv.
weatherAUSThe weatherAUS dataset is a data frame containing over 140,000
daily observations from over 45 Australian weather stations.
DateThe date of observation (a Date object).
LocationThe common name of the location of the weather station.
MinTempThe minimum temperature in degrees celsius.
MaxTempThe maximum temperature in degrees celsius.
RainfallThe amount of rainfall recorded for the day in mm.
EvaporationThe so-called Class A pan evaporation (mm) in the 24 hours to 9am.
SunshineThe number of hours of bright sunshine in the day.
WindGustDirThe direction of the strongest wind gust in the 24 hours to midnight.
WindGustSpeedThe speed (km/h) of the strongest wind gust in the 24 hours to midnight.
Temp9amTemperature (degrees C) at 9am.
RelHumid9amRelative humidity (percent) at 9am.
Cloud9amFraction of sky obscured by cloud at 9am. This is measured in "oktas", which are a unit of eigths. It records how many eigths of the sky are obscured by cloud. A 0 measure indicates completely clear sky whilst an 8 indicates that it is completely overcast.
WindSpeed9amWind speed (km/hr) averaged over 10 minutes prior to 9am.
Pressure9amAtmospheric pressure (hpa) reduced to mean sea level at 9am.
Temp3pmTemperature (degrees C) at 3pm.
RelHumid3pmRelative humidity (percent) at 3pm.
Cloud3pmFraction of sky obscured by cloud (in "oktas": eighths) at 3pm. See Cload9am for a description of the values.
WindSpeed3pmWind speed (km/hr) averaged over 10 minutes prior to 3pm.
Pressure3pmAtmospheric pressure (hpa) reduced to mean sea level at 3pm.
ChangeTempChange in temperature.
ChangeTempDirDirection of change in temperature.
ChangeTempMagMagnitude of change in temperature.
ChangeWindDirectDirection of wind change.
MaxWindPeriodPeriod of maximum wind.
RainTodayInteger: 1 if precipitation (mm) in the 24 hours to 9am exceeds 1mm, otherwise 0.
TempRangeDifference between minimum and maximum temperatures (degrees C) in the 24 hours to 9am.
PressureChangeChange in pressure.
RISK_MMThe amount of rain. A kind of measure of the "risk".
RainTomorrowThe target variable. Did it rain tomorrow?
