WHAT EXPLAINS THE MISSING HOURS IN THE AIR QUALITY DATA?

Published monitoring data contains null hourly readings clustered around seasonal peaks.

DISCUSS

WHY WE'RE ASKING

Because the annual average that drives public advisories is computed from exactly the hours that are missing.

WHAT WE KNOW

Null hourly rows exist in the published dataset.
The gaps cluster seasonally.

WHAT WE DON'T KNOW

Whether downtime logs exist.
How averages are computed around nulls.

SUPPORTING QUESTIONS

1.IS THERE A PUBLISHED DOWNTIME LOG?
2.HOW ARE ANNUAL AVERAGES COMPUTED AROUND NULL HOURS?
3.ARE THE GAPS CALIBRATION OR FAILURE?
