Air Quality Monitoring

[Julian]

This discussion is about the air quality monitoring that will be taking place in Chorlton and Chorlton Park as part of the ‘Our Streets Chorlton’ and other projects and initiatives that may be going on.

We will be using Earthsense Zephyr air quality monitoring stations with in Chorlton. One will be permanently located for the duration of the project at ‘Four Banks’ the junction of Wilbraham Road and Barlow Moor Road. The data generated from them will be open data and will be online in the near future.

Even though the AQ monitors are still bedding in, we are getting some interesting readings back from:
Four Banks:
NO, NO2 & O3

and PM1, 2.5 &10

Darley Avenue
NO, NO2 & O3

and PM1, 2.5 & 10

I’ve started adding the raw AQ data to our Github. Can find it here:

OpenDataManchester/data

There are two folders, one for each of the monitors. I’ll be downloading the raw data weekly & uploading every Monday morning for previous week. Will upload both CSV and KML files.

Can download the data with time average intervals at 15m, 1 hour, 8 hour or 24 hour but I’m uploading the non-averaged data, so it gives it at 1m intervals.

Happy to upload averaged ones too, but figure that can be done manually if needed? Any thought?

This is a great inverse correlation from the Four Banks Air Quality sensor . From a comment on Twitter it seems that due to the stable weather over the last week this pattern has been pretty marked.

Here are charts for w/c 22 Feb 21

Note the spike in PM10 on Darley Avenue, around 9pm on Sunday 28 Feb - not sure what this could be?
