Does the ‘exclude exceptional events’ option exclude only EPA regionally-concurred exceptional events or all flagged events?

Choosing the “Exclude exceptional events data” option excludes all flagged exceptional events, regardless of concurrence. Longer answer – States can flag data that may have been influenced by an exceptional event (e.g. high winds, wildfire). As a user of AirData, you can choose to exclude these flagged data. This option is available in the Air Quality Statistics Report and Monitor Values Report. In the Air Quality Statistics Report, there is not a way to tell which, if any, statistics are affected by including/excluding exceptional events. However, in the Monitor Values Report, there is a column that indicates whether there were any flagged data ('NONE'), whether flagged data were included ('INCLUDED') or excluded ('EXCLUDED').
