ANNEX III U.K. INFORMATION SUBMITTED BY MEMBER STATES TO THE COMMISSION AND CRITERIA FOR AGGREGATING DATA AND CALCULATING STATISTICAL PARAMETERS

I. Information to be submitted to the Commission U.K.

The following table stipulates the type and amount of data Member States are to submit to the Commission:

a Se definition of AOT40 in Section I of Annex I.
b Maximum daily 8-hour mean (see section II of Annex I note (a)).
c Value to be reviewed, pursuant to Article 11(3), in the light of developing scientific knowledge.
	Type of station	Level	Averaging/accumulation time	Provisional data for each month from April to September	Report for each year
Information threshold	Any	180 μg/m3	1 hour	for each day with exceedance(s): date, total hours of exceedance, maximum 1 hour ozone and related NO2 values when required, monthly 1 hour maximum ozone	for each day with exceedance(s): date, total hours of exceedance, maximum 1 hour ozone and related NO2 values, when required
Alert threshold	Any	240 μg/m3	1 hour	for each day with exceedance(s): date, total hours of exceedance, maximum 1 hour ozone and related NO2 values, when required	for each day with exceedance(s): date, total hours of exceedance, maximum 1 hour ozone and related NO2 values when required
Health protection	Any	120 μg/m3	8 hours	for each day with exceedance(s): date, 8 hours maximumb	for each day with exceedance(s): date, 8 hours maximumb
Vegetation protection	Suburban, rural, rural background	AOT40a = 6 000 μg/m3·h	1 hour, accumulated from May to July	—	Value
Forest protection	Suburban, rural, rural background	AOT40a = 20 000 μg/m3·h	1 hour, accumulated from April to September	—	Value
Materials	Any	40 μg/m3 c	1 year	—	Value

As part of the yearly reporting, the following must also be provided, if all available hourly data for ozone, nitrogen dioxide and nitrogen oxides of the year in question have not already been delivered under the framework of Council Decision 97/101/EC(1):

• for ozone, nitrogen dioxide, nitrogen oxides and the sums of ozone and nitrogen dioxide (added as parts per billion and expressed in μg/m³ ozone) the maximum, 99.9th, 98th, 50th percentile and annual average and number of valid data from hourly series,

• the maximum, 98th, 50th percentile and annual average from series of daily 8-hour ozone maxima.

Data submitted in the monthly reports are considered provisional and are to be updated, if necessary, in subsequent submissions.

II. Criteria for aggregating data and calculating statistical parameters U.K.

Percentiles are to be calculated using the method specified in Council Decision 97/101/EC.

The following criteria are to be used for checking validity when aggregating data and calculating statistical parameters:

a In cases where all possible measured data are not available, the following factor shall be used to calculated AOT40 values: * being the number of hours within the time period of AOT40 definition, (i.e. 08:00 to 20:00 h CET from 1 May to 31 July each year, for vegetatin protection and from 1 April to 30 September each year for forest protection).
Parameter	Required proportion of valid data
1 hour values	75 % (i.e. 45 minutes)
8 hours values	75 % of values (i.e. 6 hours)
Maximum daily 8 hours mean from hourly running 8 hours averages	75 % of the hourly running 8 hours averages (i.e. 18 8 hours averages per day)
AOT40	90 % of the 1 hour values over the time period defined for calculating the AOT40 valuea
Annual mean	75 % of the 1 hour values over summer (April to September) and winter (January to March, October to December) seasons separately
Number of exceedances and maximum values per month	90 % of the daily maximum 8 hours mean values (27 available daily values per month) 90 % of the 1 hour values between 8:00 and 20:00 Central European Time
Number of exceedances and maximum values per year	five out of six months over the summer season (April to September)
