Read this record carefully

PM2.5 describes fine particulate matter. This example averages two synthetic hourly channels; no EPA correction or AQI calculation is applied. Real use would require a documented correction, quality checks and specialist review.

Missing and rejected intervals contribute no valid concentration. Stale and offline examples retain clearly dated history while withholding a current value.

Trace the source and method

The public example is derived from a local synthetic fixture. Private metadata is excluded by an explicit export allowlist.
