Uncoloured provinces have no monitoring station — that is absence of data, not clean air.
PM2.5 by province

Satellite fire detections against PM2.5
Hotspots detected in the last 7 days by province, with that province's latest ground PM2.5 reading.
⚠ A hotspot is not a fire, and a count is not blame. It is a thermal anomaly in a ~375m satellite pixel. Cloud hides them, industrial heat and gas flares trigger them, and one fire spanning several pixels is counted several times. A province may rank high simply because the sky was clear when the satellite passed.

Three separate layers, as TMD publishes them. They overlap and must not be added together — there is no single cloud-cover figure in this data.
TMD's forecast API does not state units for any field. Wind is read as km/h because the department's own observation feed publishes wind in km/h and the values match that scale; if that reading is wrong, every wind figure here is wrong by the same factor.

These count measurements only. Forecasts are held in a separate table and are never added to them.
Province PM2.5 is the mean of that province's stations from their latest reading within 24 hours. Bangkok has around 60 stations while most provinces have one, so averaging per station is what makes provinces comparable. A -1 in the source means not measured, not zero, and is excluded.
