This is a legislation item that originated from the EU

ANNEX IU.K.

(A) Data requirements U.K.

(1) Reporting of time U.K.

All time references shall be made available in accordance with the ISO standard 8601:2004(E) using the extended format (YYYY-MM-DDThh:mm:ss ± hh:mm) that includes the information on difference from UTC.

The time stamp refers to the end of the measurement period.

(2) Number of digits and rounding U.K.

Data should be made available with the same number of digits as they are used in the monitoring network.

Rounding has to be the very last step of any calculation, i.e. immediately before comparing the result with the environmental objective and has to be done only once. By default the system will perform rounding of the data made available where appropriate following the commercial rounding rules.

(3) Equivalence U.K.

When more than one assessment method is used at a specific location, data should be supplied using the assessment method exhibiting the lowest uncertainty at that specific location.

(4) Standardisation U.K.

The provisions set out in Part IV of Annex IV to Directive 2004/107/EC and Part C of Annex VI to Directive 2008/50/EC should apply to the reciprocal exchange of information.

(5) Provisions for PM2,5 U.K.

Limit values plus margin of tolerance U.K.

For PM2,5, in accordance with Part E of Annex XIV to Directive 2008/50/EC, the following sum of limit value (LV) + margin of tolerance (MOT) shall apply in the respective years mentioned below:

YearLV + MOT
200830
200929
201029
201128
201227
201326
201426
201525
Calculation of the Average Exposure Indicator (AEI) in accordance with Part A of Annex XIV to Directive 2008/50/EC U.K.

Calculation is made for each individual year, calculating PM2,5 annual means for each of the selected sampling points. The selection of the sampling points has to be evident from the appropriate information made available.

Valid annual means complying with the data quality objectives are averaged over all designated AEI sites of the Member State to obtain an annual average.

The procedure is repeated for each of the 3 years, and the three annual averages are then averaged to obtain the AEI.

The AEI shall be made available annually as a three-year running mean. In case of a need to update any of the data that could directly or indirectly (through selection of sampling point) influence the AEI, the complete update of all affected information is necessary.

(B) Environmental objectives and reporting metrics U.K.

a

LV: limit value, LVMT: Limit value plus margin of tolerance, TV: target value, LTO: long-term objective, INT: Information threshold, ALT: Alert threshold, CL: Critical level, NAT: Assessment of natural contribution, WSS: Assessment of winter-sanding and -salting, ERT: Exposure reduction target, ECO: Exposure concentration obligation.

The list includes all pollutants with monitoring requirements referred to in Directives 2004/107/EC and 2008/50/EC. A list including further pollutants on which Member States shall have reciprocal data exchange, as available, is kept by the European Environment Agency and is made available at the portal.
