SO2 {rpanel}

Sulphur dioxide measurements over Europe

Description

The data document values of SO2, on a log scale, from monitoring stations across Europe from 1990 to 2001. The data were collected through the 'European monitoring and evaluation programme' (EMEP) and they are available at https://www.emep.int. The data recorded here have been organised into a convenient form for analysis.

The data file consists of six variables: site: a site code for the monitoring station longitude: longitude of the monitoring station latitude: latitude of the monitoring station year: year of measurement month: month of measurement logSO2: SO2 measurement on a log scale

## Not run: 
  Month     <- SO2$month + (SO2$year - 1990) * 12
  Year      <- SO2$year + (SO2$month - 0.5) / 12
  Location  <- cbind(SO2$longitude, SO2$latitude)
  back      <- I
  if (require(maps)) {
  	mapxy <- map('world', plot = FALSE,
              xlim = range(SO2$longitude), ylim = range(SO2$latitude))
      back  <- function() map(mapxy, add = TRUE)
