Information About the LRAPA PM2.5 Concentration and Air Quality Index

Lawrence Berkeley National Laboratory is recommendening using the LRAPA correction factor during this wildfire event. As such, during the wildfire event, will show PM2.5 concentrations and AQIs with and without the LRAPA correction.

Applying the correction will consistently report lower (better) PM2.5 concentrations and lower (better) AQIs. The LRAPA correction factor was developed by the Lane Regional Air Protection Agency. It was developed for Purple Air sensors in Lane County, Oregon where PM2.5 levels are primarily driven by winter time wood smoke from home wood heating.

For details about the correction factor, see LRAPA PurpleAir Monitor Correction Factor History.
