#' Example data for deweather
#'
#' The `road_data` dataset is provided as an example dataset as part of the
#' `deweather` package. The dataset contains hourly measurements of air
#' pollutant concentrations, wind speed and wind direction collected at the
#' Marylebone (London) air quality monitoring supersite between 1st January 1998
#' and 23rd June 2005.
