20/… @stevedouble @DefraGovUK should be watching ozone #AirPollution reported by monitors such as #YarnersWood today cc @GeraintDaviesMP @CommonsEAC @CommonsEFRA @APPGairpoll
Must-read by @ExpressNathan | Choking #smog cloud to cover UK express.co.uk/news/weather/1…
22/… #AirPollution alerts are in place by 4pm for Greater London, South East, South West, West Midlands regions at the following sites << More to come cc @ExpressNathan uk-air.defra.gov.uk/latest/alerts#…

24/... Lots of useful resources here for those wanting to know more about #AirPollution episodes cleanair.london/hot-topics/cod…
#CodeRed 10pm | HIGH ozone #AirPollution in 7 UK regions (North Wales, London, South East, South Wales, South West, East Midlands, West Midlands). And legally required #PollutionAlert triggered at 10 locations. Still no media release from @DefraGovUK! cleanair.london/app/uploads/CA…
.@DefraGovUK hasn't sent a media release to journalists and weather reporters warning of HIGH ozone #AirPollution since 21 April 2011 when it splashed front pages. Seems they didn't enjoy attention and questions! cc @ExpressNathan uk-air.defra.gov.uk/news?view=149 & cleanair.london/app/uploads/CA…
.@DefraGovUK now publishes #InformationBulletins (normally used for statistical releases) on an obscure website used by experts (ie Defra UK Air) instead of sending a media release to journalists and weather reporters uk-air.defra.gov.uk/news
28/... Outcome vs forecast on Saturday 13 August 2022. @DefraGovUK @metoffice hadn't even mentioned HIGH in their forecast!
#CodeRed HIGH ozone #AirPollution expected in many areas again on Sunday (14/8/22). Possible again Monday before relief Monday evening-Wednesday as winds turn south westerly and rain arrives. Good summary from @LondonAir londonair.org.uk/Londonair/Fore…. See uk-air.defra.gov.uk

31/... Still no #PollutionAlert from @stevedouble after #NorthamptonSpringPark breached the 1-hr ozone #AirPollution legal threshold at 3pm and 4pm today. Presumably, he's hoping to miss the news cycle for @BBCNews @Channel4News @itvnews @ExpressNathan @adamvaughan_uk and others
