Two datasets Milan.summer and Milan.winter, each containing 5 air pollutants: daily maximum of NO2, NO, O3 and SO2, daily mean of PM10; and 6 meteorological covariates: maximum precipitation, maximum temperature, maximum humidity, mean precipitation, mean temperature and mean humidity.
A \(1968*12\) data frame and a \(1924*12\) data frame.
The summer period corresponds to the period 30 April - 30 August between 2003 and 2017 and thus the dataset contains \(1968\) observations. The winter period corresponds to the period 32 November - 27(28) February. The records start from 31 December 2001 until 30 December 2017 and thus the dataset contains \(1924\) observations.
