Notes: Exceedances of the NO2 1-hour mean objective (200µg/m3 not to be exceeded more than 18 times/year) are shown in bold. (1) Data capture for the monitoring period, in cases where monitoring was only carried out for part of the year. (2) Data capture for the full calendar year (e.g. if monitoring was carried out for 6 months, the maximum data capture for the full calendar year is 50%). (3) If the period of valid data is less than 85%, the 99.8th percentile of 1-hour means is provided in brackets. All automatic monitoring data for both sites LS5 and LS6 has been ratified – Table A.
