Disclaimer:

The air-quality data you are downloading is raw data.

If you are downloading sensor data with sensor IDs that begin with no prefix or with SA (from PurpleAir or AirU sensors), these PM2.5 concentrations are based on light scattering and provide only relative measurements. We are continually working to develop correction factors to enable you to more accurately estimate PM2.5 concentration from these sensors. If you would like the most up-to-date correction factors, please contact Tofigh Sayahi [tofighsayahi@chemeng.utah.edu who can provide these.

If you are downloading data from the Utah Division of Air Quality (DAQ) (named: Hawthorne), this information is considered a gold standard and does not require correction, but it is considered preliminary until it has been quality assured. Quality assured air-quality DAQ data can be downloaded from the EPA.
