The columns in the data set represent the precipitation weighted mean concentrations of ions for the year 1986, for 47 sites in the United Kingdom.
|Rain||Rain (measured in mm)|
|x||x-coordinate (measured in cm)|
The measurement of NH4+ for site number 35 was not available and is represented by NA in the data set. The x- and y-cordinates were measured in cm from a map of the UK.
