This is "Raw data" and has not yet been validated.

Note: Forest fire PM2.5 estimates are based on data collected during the 2002 Oregon forest fires and are typically lower than the PM2.5 estimates made during non-forest fire conditions. For forest fire smoke, the Wildfire Air Quality Health Rating should supersede the non forest fire PM2.5 estimate.
