Spatial and Temporal Pattern of PM2.5 Compliance (Approximate)
What is na Exceptional Event? (EE)
Causality Pattern
Temporal Pattern
According to the EE Rule, observationas can be EE-flagged if the concentration exceeds the standard due to the exceptional event.
- The leftmost figure shows a case when the 'exceptional' concetration raises the level above the standard.
- In the next case, the concentration from controllable sources is sufficient cause the exceedance. Such an exceedance is not a 'but for' case and should not be flagged.
- In the third case, there is no exceedance, hence no justification for EE flag.
