weatherAUSR Documentation

Daily weather observations from multiple Australian weather stations.

Description

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.

Usage

weatherAUS

Format

The weatherAUS dataset is a data frame containing over 140,000 daily observations from over 45 Australian weather stations.

Date

The date of observation (a Date object).

Location

The common name of the location of the weather station.

MinTemp

The minimum temperature in degrees celsius.

MaxTemp

The maximum temperature in degrees celsius.

Rainfall

The amount of rainfall recorded for the day in mm.

Evaporation

The so-called Class A pan evaporation (mm) in the 24 hours to 9am.

Sunshine

The number of hours of bright sunshine in the day.

WindGustDir

The direction of the strongest wind gust in the 24 hours to midnight.

WindGustSpeed

The speed (km/h) of the strongest wind gust in the 24 hours to midnight.

Temp9am

Temperature (degrees C) at 9am.

RelHumid9am

Relative humidity (percent) at 9am.

Cloud9am

Fraction 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.

WindSpeed9am

Wind speed (km/hr) averaged over 10 minutes prior to 9am.

Pressure9am

Atmospheric pressure (hpa) reduced to mean sea level at 9am.

Temp3pm

Temperature (degrees C) at 3pm.

RelHumid3pm

Relative humidity (percent) at 3pm.

Cloud3pm

Fraction of sky obscured by cloud (in "oktas": eighths) at 3pm. See Cload9am for a description of the values.

WindSpeed3pm

Wind speed (km/hr) averaged over 10 minutes prior to 3pm.

Pressure3pm

Atmospheric pressure (hpa) reduced to mean sea level at 3pm.

ChangeTemp

Change in temperature.

ChangeTempDir

Direction of change in temperature.

ChangeTempMag

Magnitude of change in temperature.

ChangeWindDirect

Direction of wind change.

MaxWindPeriod

Period of maximum wind.

RainToday

Integer: 1 if precipitation (mm) in the 24 hours to 9am exceeds 1mm, otherwise 0.

TempRange

Difference between minimum and maximum temperatures (degrees C) in the 24 hours to 9am.

PressureChange

Change in pressure.

RISK_MM

The amount of rain. A kind of measure of the "risk".

RainTomorrow

The target variable. Did it rain tomorrow?
