#' @title PM10 dataset
#' @description 
#' Concentration of partical matter of diameter 10 micrometers or smaller (\code{PM10}) 
#' is one of the most widely adopted measurements for assesment of ambient air quality.
#' In this dataset, we provide \eqn{175} measurement of daily temporal distribution of \code{PM10}
#' in Graz, Austria, collected between December 2004 and June 2005. 
#' 
#' For the purpose of this R package, raw data of 48 observations per day, was transformed
#' to functional objects in Fourier basis using \pkg{fda} package.
