ANNEX I. Observed Exceedances and Annual Statistics
Observed exceedances of ozone threshold values and annual statistics
in 1996 at individual monitoring stations reporting in the framework of the Council
Directive 92/72/EEC on air pollution by ozone.
Information on ozone exceedances and concentrations for the individual
stations reporting in the framework of the Ozone Directive over the period 1 January 1996
- 31 December 1996 is available in computer readable form only. Upon request a diskette
containing the following tables is available:
Table I.1: Number of days on which exceedances of threshold
values (180 µg/m3 and 200 µg/m3 for hourly values; 110 µg/m3
for 8-hourly values and 65 µg/m3 for daily values) were observed at reporting
monitoring stations; period 1 January - 31 December 1996.
Table I.2: The longest period of consecutive days on which
exceedances of threshold values were observed at reporting monitoring stations; period 1
January - 31 December 1996.
Table I.3: Average length (in days) of periods of consecutive
days on which exceedances of threshold values were observed at reporting monitoring
stations; period 1 January - 31 December 1996.
Table I.4: Annual statistics (percentiles and maximum values) of
hourly and moving eight hourly ozone concentrations for reporting monitoring stations; all
concentrations in µg/m3; period 1 January - 31 December 1996.
Table I.5: Annual statistics (averaged, 50-, 95- and 98-
percentile values) of hourly NOx concentrations for reporting monitoring
stations; all concentrations in µg/m3; period 1 January - 31 December 1996.
Table I.6: Annual statistics (averaged, 50-, 95- and 98-
percentile values) of hourly NO2 concentrations for reporting monitoring
stations; all concentrations in µg/m3; period 1 January - 31 December 1996.
Table I.7: Annual statistics (averaged, 50-, 95- and 98-
percentile values) of daily VOC concentrations for reporting monitoring stations; all
concentrations in µg/m3; period 1 January - 31 December 1996.
Notes to the Tables
Table I.1
Exceedances of the threshold value of 360 µg/m3 for hourly
values has been observed in 1996 at 2 stations:
country | station name & city | date, time | max conc (µg/m3) |
Greece | Liosia, Athens Marousi |
21 May 1996, 14.00 21 May 1996, 13.00 |
391 361 |
In Table I.1 it is also indicated when no exceedance of (one or more) threshold values
was observed at the station. This information has not been submitted by the Member States
and is inferred from the available data. In cases where the information was insufficient
for an unambiguous answer a "?" is printed.
