Hi! There's a group in Mobile County Alabama who has been using the purple air monitors, but they haven't had the ability to go through the data to both pull it and look for trends. I'm looking for anyone is interested in helping them out- review it and look for trends or interesting points.

I noticed @guolivar had a nice post on these monitors a while back. I've also been hearing interest on them from another group in Wisconsin. It would be great to learn more about them!

I wonder if this is something @sagarpreet's library could help with. Have they posted their data somewhere? I know they can share it via Weather Underground, and maybe @sagarpreet can have it appear as a layer alongside weather and other toxic release and report/alert data in his new library?

I'm sorry, this got buried in my inbox ... I don't even remember seeing a notification about the original question! The short answer is that I don't have an "off the shelf" solution but it is something that my group have been mulling over for the past few months. Purple Air says that their data is easiest seen through their map and that they often share their data with researchers (I thought the data belonged to those who took the measurements but that's not the point here). So, my suggestion would be to get in touch with PurpleAir to get access to the live data. If the folks at Mobile County have the data they want analysed at hand (offline) I'm happy to prepare some quick summaries but can't commit to a tight timeframe and my group's plans are for the next months to have something ingesting PurpleAir data.

If no one has volunteered to help them out, I'd be glad to try. Send me an email for a contact person. Or send them my email: joanjeff@centurylink.net

You can pull PurpleAir data off of purpleair.com/sensorlist. You should be able to download any sensor's data as a .csv file and then work with it in Excel, R, or Python (your choice depending on what you're trying to do and what you're familiar with).

Hi! The person who was asking for this has been offline for the past few weeks. I'll ping back as soon as I hear from them! Thanks for offering this.
