Latest Cumulus MX V4 release 4.0.1 (build 4023) - 16 May 2024
(Note that 4.1.0 (build 4024) - 05 June 2024 remains available, but usage of this version is not recommended - particularly for Davis stations - and the included utility in this distribution for migrating to v4 is known to contain errors affecting conversion of dayfile.txt)
Latest Cumulus MX V3 release 3.28.6 (build 3283) - 21 March 2024
Legacy Cumulus 1 release 1.9.4 (build 1099) - 28 November 2014

Re: Air quality readings in cumulusmx database
Sorry to resurrect this slightly old thread, but on this topic is it possible to graph the air quality readings against the chosen Index? My (Airlink) sensor data is being collected and can be seen in Recent Charts, but (and maybe I am just being dense) I can't see a way to include the index. Is it that this data isn't stored?

Re: Air quality readings in cumulusmx database
There isn't a column allocated in the database for AQI. You may have to convince Mark that it is worth adding

Re: Air quality readings in cumulusmx database
Adding the AQI requires knowing about the locale (or some parameter defining the country you wish to use) because it is dependent on which country you are in. AQI is not as simple as it seems.
See my post on this subject.
And of course it is up to Mark to decide what he does.

Re: Air quality readings in cumulusmx database
Why would it?
The values being added in to a database have nothing to do with what country you're in?!

Re: Air quality readings in cumulusmx database
I think this can be seen both ways. Yes, Air Quality Index is basically just a number that could be stored on database (or at least I can’t figure out why not).
The problem is that the number itself does not tell anything if you do not know which country standard has been used to calculate it. As Hans wrote on the linked post, US AQI has scale from 1 to 500, British has scale from 1 to 10 and EU has two different specifications with scales from 1 to 5 and 1 to 100. And of course Australians have scale of 1 to 200. On the other hand, if you have access to cmx database, you probably should anyway know what standard is used, so it is still useful without any metadata.

Re: Air quality readings in cumulusmx database
@Mapantz: exactly as @SamiS wrote.
The problem I see with the AQI is that it is not objective. It is a value according to some countries standard and studying that AQI shows it is pretty manipulative. As if the countries institutes know what health related to particulate matter is.
And because my last discussion with beteljuice was about lung related health - he died of failing lungs and knew what he was talking about - i will kind of dedicate this subject to him. As a human being you better know which concentration - which is the only objective measurement we do - is bad for your health than worry about the AQI which is a nonsense quantity. A value in a database does not make it a good or relevant value.
And yes, this is an opinion on interpretation of particulate matter.

Re: Air quality readings in cumulusmx database
My point was, the values can be added to a database as is. What you do with them after is up to you..
