FoE UK are organising a citizen science air quality measurement programme.

Get involved here:

Clean Air Kit

Here's mine:

The results will be analysed, as I understand it, in connection with King's College, London.

My dot on the map will be bad, very bad ...

[Edit: SSL certificate installed ...]

... and after two weeks it goes back for analysis.





It's been quite windy these last two weeks so the result might not be as bad as predicted. Of course, post-Brexit we will be at liberty to ingest as much NO2 and as many diesel particulates as we like. Glad confident morning! Though the afternoons might have a brownish tinge.

Though FoE haven't written back yet, it appears that the result from their map is:

"Average NO2 (in μg/m3) during that period = 23.71"

... which compares favourably with the EU average annual limit of 40 µg/m3. I had better stop complaining.

The wonderful people at SEDAC have produced a grid of ground-level NO2 at ~10 km resolution.

Here's my version of that data for western Europe:


... and my pixel has ~14 µg/m3 (assume 1 ppb = 1.88 µg/m3), so not far off given that the pixel is rather large and I pretty much live under a dual-carriageway.

Netherlands/Germany not so good.
