Air Quality In Grindleford

A year our so ago a few residents of the village were approached by a local science enthusiast to see whether there was scope to install a small number of air quality monitors in the neighbourhood. The monitors would be a part of a growing global network gathering really useful data. Here is a message we received a few days ago which we thought it would be nice to share with residents:
“It is now roughly nine months since we deployed our first Air Quality sensors in the Hope Valley – and boy have things changed a bit in that time!
In the interim, your sensors have been quietly logging data and this has been collected in the Sensor Community database where it is freely available to view and as we approach the first year of data we plan to run a piece in the Hope Valley Climate Action monthly newsletter (April) to review the project and share the data we have logged.
Ahead of that, I wanted to connect with you again to say thanks for being a host and also share with you the links to the data such as you might want to review yourself.
You will find a series of links and other materials below.
I am not an air quality scientist or a data scientist so I can only offer a few general observations, and these are below. However if you have expertise in any of these areas and would like to share insights, please contact me.

Overall yes, our air quality is very good based on the comparable data we see elsewhere on the global sensor community, especially in the summer months.

There is very little on the particulate scales that registers and it is almost always well below any threshold.

You can see the global view of air quality on a map and then zoom in on areas using the link (1) below.

Note that you can aggregate values by zooming out to where several hexagons converge into one and then clicking on that one to see all values registered.

Clicking on a sensor ID shows detailed data for that location. Alternately using link (2) below will show you a full year’s data in a dashboard with many options.

Please note you will need to put the sensor ID for the location you wish to view onto the end of the URL (in red) and these are in the table below.

In the winter I have noticed a general propensity for higher particulate count in the villages as opposed to out of them.

This is most likely due to wood and coal burning in homes but it is very localised and does not seem to have a widespread impact beyond a street or two.

Even then it’s not a very high reading, but it is noticeable.

Also I have observed that the particle sensors are affected by water droplets in the air so when we have fog conditions they often read very high particulate numbers.

Note that by changing the sensor ID at the end of this URL you can see discrete data for each location listed in the table below.

EXAMPLE: Two sensors showing very different readings – both correct

This discrepancy is an example of what happens when one sensor is in direct sunlight and one is in shade.”
