Documentation

On this Picostat.com statistics page, you will find information about the co2 data set which pertains to Mauna Loa Atmospheric CO2 Concentration. The co2 data set is found in the datasets R package. You can load the co2 data set in R by issuing the following command at the console data("co2"). This will load the data into a variable called co2. If R says the co2 data set is not found, you can try installing the package by issuing this command install.packages("datasets") 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 co2 R data set. The size of this file is about 11,113 bytes.


Mauna Loa Atmospheric CO2 Concentration

Description

Atmospheric concentrations of CO2 are expressed in parts per million (ppm) and reported in the preliminary 1997 SIO manometric mole fraction scale.

Usage

co2

Format

A time series of 468 observations; monthly from 1959 to 1997.

Details

The values for February, March and April of 1964 were missing and have been obtained by interpolating linearly between the values for January and May of 1964.
