Pollutants

A list of the pollutants, with a short description, can be found in the pollutants_id table available in this package. This table comes from http://dd.eionet.europa.eu/vocabulary/aq/pollutant/view. In the europollution package, pollutants are called using their code in the pollutants_id table. For instance, to download data on sulphur dioxide and ozone, the following pollutant argument should be passed to the functions: pollutants = c("SO2", "O3").

Note that all pollutants are not be available for each station. The functions provided in this package enable to download all the available data.

ep_search_pollutant function

The function ep_search_pollutant enables to find the code for a pollutant. To find the code for sulphur dioxide, use the following command for example:

europollution::ep_search_pollutant("sulphur")

The function returns every entry in the pollutant_id table which contains the word "sulphur". The code of interest is "SO2" and can be used in the other functions.
