The orange values is from dashboard, yellow is from map values

The map value is close to qingping 2 air sensor

Why is the dashboard is higher?(already applied calibration, correction and epa)

Already figured it out; As mentioned in other post: EPA calibration algo is applied to air gradient map, in order to be consistent in dashboard, EPA calibration needs to be applied in PM 2.5. Cheers

Thanks for the clarification. I thought the EPA correction was already applied.
