(1) Decision 97/101/EC lays down a system for reciprocal exchange of information and data on ambient air pollution.

(2) It is appropriate to amend the Annexes to that Decision in order to adapt the list of pollutants covered as well as requirements on additional information, validation and aggregation.

(3) The measures provided for in this Decision are in accordance with the opinion of the Committee instituted by Article 12(2) of Council Directive 96/62/EC(2),

HAS ADOPTED THIS DECISION:

Article 1

ANNEX

"ANNEX I

LIST OF POLLUTANTS, STATISTICAL PARAMETERS AND UNITS OF MEASUREMENT

1. Pollutants listed in Annex I to Directive 96/62/EC on air quality

2. Pollutants not listed in Annex I to Directive 96/62/EC on air quality

Pollutants to be reported under Directives other than Directive 96/62/EC are listed in Section 3 under Nos 14 and 15. Pollutants only to be reported if available are listed under Nos 16 to 63.

3. Pollutants, units of measurement, averaging times:

>TABLE>

4. Data, calculated over the calendar year, to be transmitted to the Commission

Member States shall send raw data or shall send raw data and statistics.

For those Member States who transfer raw data and statistics the following statistics are required.

- For pollutants 1 to 61:

the arithmetic mean, the median, the percentiles 98 (and 99,9 which may be transmitted on a voluntary basis for pollutants for which the mean is calculated over one hour) and the maximum calculated from raw data corresponding to the recommended averaging times indicated in the table above,

- for pollutants 62 and 63:

total monthly deposition, calculated from raw data corresponding to the recommended averaging times indicated in the table above.

The yth percentile should be selected from the values actually measured. All the values should be listed in increasing order:

>PIC FILE= "L_2001282EN.007301.TIF">

The yth percentile is the concentration Xk, where the value of k is calculated as follows:

>REFERENCE TO A GRAPHIC>

with q being equal to y/100 and N the number of values actually measured.

The value of (q x N) should be rounded off to the nearest whole number.

All the results should be expressed at the following conditions of temperature and pressure: 293 K and 101,3 kPa, except for pollutants 62 and 63. For particle bound components, data from the year 2001 and onwards should be reported at ambient conditions.

5. Data transmission to the Commission:

Data shall be transmitted by one of the following data formats: ISO 7168 version 2 extended format, NASA-AMES 1001/1010 or DEM(1) compatible format; or in DEM database:

The Commission will confirm receipt of data and the number of stations and pollutants.

(1) Data exchange module provided on behalf of the European Commission.

ANNEX III

DATA VALIDATION PROCEDURE AND QUALITY ASSURANCE

All transmitted data are deemed to be valid.

It is the responsibility of the Member States to ensure that a quality assurance procedure is in place, which meets in general the objectives of this Decision and in paricular the objectives of the relevant Directives.

ANNEX IV

CRITERIA FOR THE AGGREGATION OF DATA AND THE CALCULATION OF STATISTICAL PARAMETERS

These criteria mainly concern the data capture

If criteria for the aggregation of data and the calculation of statistical parameters have not been laid down in EU directives the following applies:

(a) Aggregation of data

The criteria for the calculaltion of one-hour and 24-hour values from data with a smaller averaging time are

>TABLE>

(b) Calculation of statistical parameters

>TABLE>

The ratio between the number of valid data for the two seasons of the year considered cannot be greater than 2, the two seasons being winter (from January to March inclusive and from October to December inclusive) and summer (from April to September inclusive)."
