				<dd3:Methodology><![CDATA[The alert threshold is 1h-value &gt; 240 &#181;g/m3.

How to report 1 hour exceedances:
An exceedance period is a continous period on a single calendar day during which the threshold was continuously exceeded. A period cannot include hours of more than a single calendar day. If more than one exceedance period occurs on a calendar day, each period must be reported separately.

Time is to be specified in Central European Time. The summer reference period is 01/04 - 30/09.

All concentration of ozone and nitrogen dioxide must be reported in &#181;g/m3. The volume must be standardised at the folllowing conditions of temperature and pressure: 293K and 101.3 kPa.

Default value for missing numerical data will be -999.]]></dd3:Methodology>
