How this helps travel recommendations

Adjusts outdoor comfort, smoke risk, northern-route viability, Bangkok temple-day quality, and whether a destination should be downgraded or avoided.

Developer reference

Best endpoint

Use the station-level AQI/PM endpoint or official feed when available; store observation time, coordinates, pollutant driver, and nearest destination.

Recommended refresh

Refresh every 15-60 minutes, with caching and backoff when the upstream fails.

Travel scoring role

Adjusts outdoor comfort, smoke risk, northern-route viability, Bangkok temple-day quality, and whether a destination should be downgraded or avoided.

Comparable / backup source

Air4Thai, OpenAQ, WAQI/AQICN, nearby stations, or Pollution Control Department reports.

Failure modes

  • Stations can go offline or report stale timestamps.
  • Coverage can be sparse outside major cities.
  • Different feeds can bucket AQI/PM values differently.
  • Dashboard markup or public-page layout can change without notice.
