Air quality in Guernsey
No monitor here publishes data we're allowed to use, so Guernsey has no measured ranking yet. Model estimates below.
Estimated: cities without a monitor
Guernsey cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
