Max Daily Pm2.5 Values?

Data API
1

Hi,

I’ve been using the API to display hourly average PM2.5 for a while - now have a specific one-time use case for plotting the maximum recorded PM2.5 value for a day, per-sensor. Is this possible through a different endpoint? In a similar system I have worked on, the minute-by-minute values are rolled into an hourly average and then the minute data is purged, so I am hoping that this is not the case. Also, this would be relatively historical max values, as in July of 2025.

Hi Quinn,

Data is averaged to create the hourly averages you have been querying, but that data is not purged. 2-minute averages are available through the API. Would querying 2-minute averages for the time period, and then identifying the highest value out of those averages per day work for your use case?
