These dataset contains daily quality air measurements in
Spain over a period of 18 years (from 2001 to 2018). The measurements refer to
several pollutants. These data are openly published by the Government of Spain.
The datasets were originally spread over a number of files and formats. Here,
the same information is contained in simple dataframe for convenience of
researches, journalists or general public. See the Spanish Government website
<http://www.miteco.gob.es/> for more information.
