odgi: Ozone Depleting Gas Index Data, 1992-2018

Description Usage Format Details Source Examples

Description

The NOAA Earth System Research Laboratory has an ozone depleting gas index (ODGI) data set from 1992 to 2018. This dataset summarizes Table 1 and Table 2 from its website in a tidy/long format. The primary interest here (for my purposes) is the ODGI indices (including the new 2012 measure). The data set includes constituent greenhouse gases/chlorines as well in parts per trillion. The primary use here is for in-class illustration.

Usage

1
data("odgi")

Format

A data frame with 756 observations on the following 4 variables.

Year

the year of observation

Area

categorical for Antarctic or Mid-latitudes

Category

categorical, whether for the particular greenhouse gas (e.g. CFC-11, CFC-12, CH3Cl) or the ODGI measures of interest to me.

Value

a numeric vector

Details

I'm working under the assumption that the constituent gases in Value is measured in parts per trillion while the ODGI measures are a separate index measure. Use with caution.
