Sažetak
Indices were devised to classify air pollution monitoring sites according to the type of expected photochemical pollution. The indices are based on two contributions: one due to the ratio of daily maximum-to-minimum ozone volume fractions and the other to observed peak values. The two contributions are combined by multiplication. The type of station is mainly described by the mentioned ratio incidence of ozone volume fractions exceeding the limit of 80 ppb. Twelve monitoring stations of the EMEP network werer classified according to this index into three groups: clean, medium and polluted, based on the data for the growth seasons (April through September) 1997 to 2000.
