COMMISSION DECISION

of 17 October 2001

mation and data from networks and individual stations measuring ambient air pollution within the
Member States

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

(3)

Having regard to the Treaty establishing the European
Community,

Having regard to Council Decision 97/101/EC of 27 January
1997 establishing a reciprocal exchange of information and
data from networks and individual stations measuring ambient
air pollution within the Member States (1), and in particular
Article 7 thereof,

Whereas:

(1)

(2)

Decision 97/101/EC lays down a system for reciprocal
exchange of information and data on ambient air pollu-
tion.

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.

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

The Annexes to Decision 97/101/EC are replaced by the text in
the Annex to this Decision.

This Decision is addressed to the Member States.

specific PAH substances and proposals for amendments to this Decision as necessary.

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.

26.10.2001

Official Journal of the European Communities

L 282/73

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

The yth percentile is the concentration X
k

, where the value of k is calculated as follows:

k = (q × N)

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

The value of (q × 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.

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

— for one-hour values:
— for 24-hour values:

(b) Calculation of statistical parameters

Minimum data capture 75 %,
At least 13 one-hour values available, not more than six succes-
sive one-hour values missing.

minimum data capture 50 %,
— for the mean and the median:
— for the percentiles 98, 99,9 and the maximum: minimum data capture 75 %.

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).’
