SmogRank / World / Europe / Sweden / Halland
Most polluted cities in Halland, Sweden
No city in Halland, Sweden has enough readings to rank for the last 7 days.
66 monitors in Sweden stopped reporting on 4 Oct, 02:00 local time. Cities that rely on them are missing from the 24-hour board and may drop from the longer ones; that isn't clean air, and they return when the data does.
A city joins this ranking with enough days of readings over the last 7 days; none here has that right now, so there is nothing to map or chart.

Estimated: cities without a monitor
Halland 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.
| City | 7-day estimate |
|---|---|
| Halmstad | ≈ 11 µg/m³ |
| Varberg | ≈ 9 µg/m³ |
| Falkenberg | ≈ 10 µg/m³ |
| Kungsbacka | ≈ 8 µg/m³ |
