Figure 14. Aerosol Ion Concentrations and Na:Mass Percentages
in TSP Samples Collected during November 1997 - June 1999
The top and bottom of each box are the 25^th and 75^th percentiles, respectively. The line within each box is the median,
and the external upper lines and lower lines are the 10^th and 90^th percentiles, respectively. Individual circles are values
outside the 10^th and 90^th percentiles.
