Data downloading

Data

You can, but with limitations on the resolution of the data. You can download the data that appears on the map graph, and that data is limited by resolution (the averaging period of the data). I’ll share the full limit list below.

If you want to download high-resolution data from any time period, you can do so using the API. If you’re not familiar with our API, you can get started with this article: About the PurpleAir API

Map Graph Limits

  • Real-time: 2 days
  • 10-minute: 3 days
  • 30-minute: 7 days
  • 1-hour: 14 days
  • 6-hour: 90 days
  • 1-day: 1 year
  • 1-week: 5 years
  • 1-month: 20 years
  • 1-year: 100 years

Here’s an example of what the list above means: If you set the “Averaging period” to “10-minute” in the map configuration menu, the graph datapoints will be 10 minutes apart, and the graph will show the last 3 days of data.
