airquality Marvellous May May manifests merely mild measurements of microscopic matter mist, marvellous!
weather Haze lowers temperature, but hides air hazard Eastbourne today experienced what was most likely a mild sea fret. It was not a thick fog, we could still see the pier from the harbour, but it was sufficient to keep temperatures below what the rest of Sussex was enjoying.
airquality Sunny Eastbourne Easter Saturday As if the filth of the world's air had been taken away somehow, particulate matter levels have dropped right back to DAQI "Low" levels this Easter weekend.
airquality Multisensory experience With the wind out of the south east at several points today the distinctive odour of the Sovereign Harbour Sewage Works was noticeable. But that was not the only unpleasant thing in the
airquality Windswept but not completely clean Storm Gareth has been making its presence felt this week with very high winds and some rain in Eastbourne. PM2.5 shows ups and downs but the maximums only reach the middle of the DAQI "Low" band, which is good news.
airquality New month same story March already and PM2.5 levels have not dropped all the way down yet. Overnight readings were Low, touching Moderate briefly. Same story during daylight today. Regional climate conditions and international pollution sources have been driving Eastbourne PM2.5 levels recently.
airquality Final surge before wind wipeout? PM2.5 yesterday was moderate during the morning, rising steadily through the afternoon and evening to very high by 2200hrs where it stayed mostly until a huge spike up to 168ug/m³ early this morning. Since then levels have dropped right off down to their lowest in six days.
airquality Peripatetic Parisian pollution policy I have been keeping an eye on the MetClim PM10 forecast for the last few days. The forecast has been accurate. The source of pollution has been Paris. How do we handle international pollution?
airquality Pollutions Sans Frontieres Varese, Italy-based @MetClim has a series of fascinating forecasting GIFs of predicted pollution patterns over several days showing how pollution is carried all around Europe.
airquality Super high PM in the AM Last night PM2.5 and PM10 levels reached new highs. PM2.5 was around the 100ug/m³ level for 7 hours until 0600 GMT this morning. The sustained high level of pollution means a high 24h average figure.
airquality Steady as she goes - shipping pollution to Eastbourne? Startling, steady increase of both PM2.5 and PM10 air pollutants in Sovereign Harbour, Eastbourne this morning. Shipping as a possible source.
airquality High PM2.5 levels The PM2.5 graphs for the last day or so are not pretty. According to DEFRA concentrations above 54ug/m³ are considered "high". As you can see from the graph below levels have been peaking above that over the last 24 hours.
airquality Once every blood-red supermoon Eastbourne has enjoyed some pleasantly PM2.5-free air over the last week. Levels have been low, only rising above 15ug/m³ once before Saturday. Since Saturday levels have climbed again. For the last
airquality Gone with the wind? What exactly led to the wonderful clearance of air pollution last night? The Defra forecast for today says, "Air pollution levels will be Low for the whole of the UK today due
airquality Dip to moderate PM2.5 has dropped from its recent sustained high of over 50ug/m³, to 20ug/m³, although it looks to be heading back up as I type. 20ug/m³ is still 68 on
airquality PM2.5 back above 50ug/m³ in Eastbourne After a few days of lower particulate pollution we are experiencing elevated PM2.5 levels again. Concentration peaked at just over 70ug/m³ overnight (AQI 158 "Unhealthy").
weather Slow wind news day Since the installation of the new weather station back in September 2018 it has seemed to me that the reported wind speeds have been low. I wonder if the anemometer supplied with this weather station kit is perhaps running slow.
airquality Temperatures dropping, PM2.5 rising With temperatures dropping to freezing on the sunshine coast, we are also seeing a marked rise in PM2.5, increasing steeply above 50 ug/m³ today. The high atmospheric pressure is probably not helping matters.
airquality The PM2.5 month in review - December 2018 Two things to highlight this month, and one to anticipate. Comparison with November Levels in December were generally lower than November. On the November graph the line was above 10μg/m³ for most
airquality Can we stop holding our breath now? Despite a distinct lack of wind PM2.5 levels have been steadily falling all day, we are no longer redlining at over 100ug/m³.
airquality On the third day of Christmas... Elevated PM2.5 levels stayed steady yesterday daytime before beginning a further increase in the evening from around 40ug/m³ at 18:00 GMT to a peak of over 115ug/m³ at 20:45 GMT.
airquality All is calm, PM2.5's a fright It's been calm since Christmas Day, and PM levels have been steadily climbing towards unhealthy levels. Certainly the PM2.5 values anyway. PM10 has also been rising but not to the same degree.
airquality Fahrenheit 451 There was a combustion event in the immediate vicinity of the SDS011 PM sensor today. PM10 spiked at over 1,050 ug/m³ and PM2.5 maxed out at around 650 ug/m³
airquality The PM2.5 month in review - November 2018 November 2018 was an interesting month. We had the early peak in pollution with Guy Fawkes' night the likely culprit. You can see that on the graph.
