R Dataset / Package DAAG / bomregions2011


On this R-data statistics page, you will find information about the bomregions2011 data set which pertains to Australian and Related Historical Annual Climate Data, by region. The bomregions2011 data set is found in the DAAG R package. You can load the bomregions2011 data set in R by issuing the following command at the console data("bomregions2011"). This will load the data into a variable called bomregions2011. If R says the bomregions2011 data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the bomregions2011 R data set. The size of this file is about 15,804 bytes.

Australian and Related Historical Annual Climate Data, by region


Australian regional temperature data, Australian regional rainfall data, and Annual SOI, are given for the years 1900-2008 or 1900-2011 or 1900-2012. The regional rainfall and temperature data are area-weighted averages for the respective regions. The Southern Oscillation Index (SOI) is the difference in barometric pressure at sea level between Tahiti and Darwin.




This data frame contains the following columns:




Eastern temperature


Southeastern region average temperature (degrees C)


Southern temperature


Southwestern temperature


Western temperature


Northern temperature


Murray-Darling basin temperature


Australian average temperature, area-weighted mean


Eastern rainfall


Southeast Australian annual rainfall (mm)


Southern rainfall


Southwest rainfall


Western rainfall


Northern rainfall


Murray-Darling basin rainfall


Australian average rainfall, area weighted


Annual average Southern Oscillation Index


Moana Loa CO2 concentrations, from 1959


Moana Loa CO2 concentrations, 1900 to 1978


CO2 concentrations, composite series


Annual average sunspot counts

The CO2 series co2law, for Law Dome ice core data. is from http://cdiac.ornl.gov/trends/co2/lawdome.html.

The CO2 series co2mlo is from Dr. Pieter Tans, NOAA/ESRL (www.esrl.noaa.gov/gmd/ccgg/trends/)

The series CO2 is a composite series, obtained by adding 0.46 to he Law data for 1900 to 1958, then following this with the Moana Loa data that is avaiable from 1959. The addition of 0.46 is designed so that the averages from the two series agree for the period 1959 to 1968

Sunspot data is from http://sidc.oma.be/sunspot-data/
