Mod O3 end May to June 2021 - Release date [02/06/2021]
'Moderate' Ozone Pollution Incident Notification for Bank holiday Monday 31st May to Wednesday 2nd June 2021 Issued: Wednesday 2nd June 2021 Widespread 'moderate' ozone was measured across London and south-east England on Monday 31st May through to Wednesday 2nd June. Ground-level ozone production was driven by the rising temperatures and sunshine over the weekend acting on local and continental precursor emissions. 'Moderate' ozone was reached at 9 sites on Monday, then 24 sites on Tuesday with locations as far west as Southampton also reaching Moderate. At the time of writing this (15:00 hrs on Wednesday 2nd June) peaks in the moderate range are again being recorded across the South-East and Greater London, however the rolling 8 hour mean requirement has not yet been reached for the day. It is important to remember that ozone is an area wide pollutant, and whilst monitoring sites are relatively sparse compared to those monitoring nitrogen dioxide they represent the wider population exposure, so a single site may represent the ozone concentrations that hundreds of thousands of people have been exposed to. The current episode is expected to continue until Thursday 3rd June when the air flow is set to become more westerly and an increase in cloud cover is forecast. The current situation can be followed on London: www.londonair.org.uk Sussex www.sussex-air.net Essex www.essexair.org.uk Hampshire www.hantsair.org.uk Sussex www.sussex-air.net including sites Berkshire, Essex and Surrey.
