PM pollution climbing Overnight PM2.5 levels continued to climb, passing 40μg/m³ at about 2300hrs, and oscillating up to 50μg/m³ at points, with brief periods of lower pollution as clearer air
weather Off the charts The e.brx.io weather station recorded a maximum of 1051.1hPa shortly before midnight on 19 Jan. Pressure stayed above 1050hPa until just after midday on 20 Jan. It looks like the high is beginning to pass by.
Meta Of the charts The new charts system involves InfluxDB and Grafana, logging data from multiple sources into one database so they can be queried together and represented on the same graph
airquality Rebooting the HPMA115S0-XXX The idea of a portable detector to take to different locations or when travelling seemed very useful. Personal exposure to PM is, after all, the key thing.
airquality Fresh start for a new decade? After a long run of fairly low levels of particulate matter pollution in Eastbourne, levels rose again as 2019 drew to a close. While on Twitter Defra was reporting low
airquality Walking in a particulate matter wonderland Air quality levels remain good in Eastbourne as Christmas approaches. This is boring but brilliant news for local residents. According to my sensor we had a brief spike in PM2.5 at the start of December
weather Sensor sensibility The temperature got down to a frosty -2°C, which is quite low for Eastbourne, especially this early in December. And as the temperature dropped so the reported particulate matter
airquality Claremont Hotel fire I have just picked up the sad news about the Claremont Hotel fire, right next to the pier on Eastbourne seafront.
airquality Horrible honk haunts the harbour For the last 24 hours or so emissions from the Eastbourne Wastewater Treatment Works have been troubling residents in the Sovereign Harbour and Langley Point areas of Eastbourne. There is nothing on the Southern Water Incident Map currently.
Meta Upgrading pywws on a pi Today I am upgrading the weather station data logging computer's software. It's going sloooooowly. But once done it should allow better data analysis. Here's what's going on...
airquality Levelling up PM2.5 levels in Eastbourne have spiked twice today to over 50µg/m³, PM10 levels followed a similar pattern.
airquality Raindrops keep falling on my particulate matter levels Eastbourne has again enjoyed some nice, low particulate matter levels this week. Floating 24h average readings for PM2.5 have not risen above 8μg/m³ in the last seven days.
airquality Eastbourne expectations Air quality in Eastbourne over the summer looks like it was generally very good, apart from the Lydd fire incident back on 24 July and the bank holiday bump on 26 August. Autumn is setting in now though.
weather Bank holiday bump It's been a brilliant bank holiday weather-wise with highs of 28°C and calm seas making for perfect sunbathing conditions on the beach, and thousands of people having been making
airquality Lydd Ranges fire fallout The cause of this evening spike in particulate matter would appear to be the fire near Lydd in Kent, 44km (27 miles) away. PM2.5 peaked at just over 240μg/m³, while PM10 peaked at just over 260μg/m³.
weather Eastbourne in bloom and a sub-Saharan plume On the evening of Tuesday 18 June we had a spectacular thunderstorm at the end of an unusually wet and unsettled period. The media widely reported more than 1,000 lightning strikes in the Eastbourne area.

airquality Marvellous May May manifests merely mild measurements of microscopic matter mist, marvellous!
weather Haze lowers temperature, 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
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.
