Minister for the environment r. vējonis 16. attachment Cabinet of 21 October 2003, the Regulation No 588 European Commission presented information about ozone pollution and data collection and statistical indicator calculation criteria i. information to be submitted to the European Commission no PO box score Monitoring stations the way the level of pollution by the time interval the preliminary data for each month from April to September the information included in the annual report of 1. Information for any of these rules referred to in annex 12, 180 mg/m3 for 1 hour per day where the information threshold exceeded: the date, the duration of the exceedance, maximum 1 hour value and, if necessary, the corresponding value of the monthly maximum of NO2 in the hour value for each day on which the information threshold exceeded: the date, the duration of the exceedance, maximum 1 hour value and, if necessary, the corresponding value of the 2. NO2 alert level any of these rules referred to in annex 12, 240 μg/m3 for 1 hour for each day during which the alert threshold has been exceeded : date, duration of the exceedance, maximum 1 hour value and, if necessary, the appropriate value for each day of NO2, which exceeded the alert threshold: date, duration of the exceedance, maximum 1 hour value and, if necessary, the corresponding value of 3. NO2 target value for the protection of human health by any of these rules referred to in annex 12, 120 μg/m3, 8 hours per day, which exceeded the target value: date, 8 hour maximum per day that exceeded the target value: date, 8 hour maximum value 4. Target value for the protection of vegetation in suburban, rural background measurements AOT40 = 6000 μg/m3 x h hours from May to July, target value 5. Indicator of forest protection for the suburban, rural background measurements AOT40 = 20000 mg/m3 x h hours, April to wake – the indicator value 6. Pointer protection of any material in this rule referred to in annex 12, 40 μg/m3 1-indicator value 2. the annual report shall also give the following information 2.1. for ozone: nitrogen dioxide, nitrogen oxide pollution-the maximum value of 99.9., 98 and 50 percentile and annual average value, as well as the annual average number of valid data hourly measurements;
2.2. maximum value of 98 and 50 percentile and annual average of daily maximum 8-hour ozone values.
3. Data, presented in the monthly reports are considered provisional, and, if necessary, clarify the following messages.

II. Criteria for collecting data and calculating statistical parameters 4. Percentile is calculated in accordance with the European Council of 27 January 1997 decision 97/101/EC "on the mutual exchange of information and data obtained by measuring the air quality network and stations".
5. Data collection and calculation of statistical parameters, use the following criteria: no PO box required a valid Parameter data rate 5.1. one hour values 75% (45 minutes) 5.2. eight hours 75% of the value of the value (6 hours) 5.3 maximum daily 8-hour average, derived from the eight-hour period every hours calculated averages 75% of the eight-hour period every hour averages (18 eight-hour daily averages) 5.4 the AOT40 for 90% of the one hour values for the period set in the calculation of the AOT40 * 5.5 annual average 75% of the one hour values in the summer period (April to September) and winter (January to March and October to December) individual 5.6. number of exceedances and maximum values during the month, 90% of the daily maximum 8-hour mean values (27 daily values per month) 90% of the one hour values from 8.00 until 20.00 o'clock by the time Central 5.7. number of exceedances and maximum values per year five out of six months over the summer season (April to September)
Note the.
Where all possible measured data are not available, the size calculation of the AOT40 uses the following formula: where: n-the total possible number of hours number of hours during the period of AOT40 definition (from 8.00 until 20.00 o'clock after Central European time each year from May 1 to July 31 of vegetation protection and from 1 April to 30 September, protection of forests);
k – measured the hour value.
