Mae Sai - They keep the Campfires Burning

Much better - Phrae Hospital

So sorry for Rongkwang Hospital. I love their ER.

Phrae Met. Station - Not Bad?

These numbers are confusing

Yes, indeed.

Xiaomi shows only the PM2.5 numbers, as far as I know.

It comes from China, they have other limits.

In the US 75 ug/m3 might be 'very unhealthy', I think.

Reliable/helpful:  https://www.airnow.gov/aqi/aqi-calculator/

https://www.iqair.com/  shows PM2.5 numbers AND the AQI.

https://aqicn.org/here   shows only the AQI.

The most of the Xiaom-Air Purifiers have a PM2.5-meter integrated. 

Very interesting to compare...

Chiang Mai on Monday suffered PM2.5 levels as a high as 66 micrograms per cubic metre (μg/m3), according to the CAPM, though the popular aqicn.org website measured levels as high as 164μg/m3 over the past 48 hours.

Very convenient.

over the past 24hrs/48hrs/one month/a year?

Some real numbers - today 8:00.

This comes from:   Chiang Rai Forum -Phrae PM2.4

made the move to Rawaii in Phuket from December to June

Very good idea.

But 'from July to the beginning of December' is not correct for Chiang Mai.

I enjoyed the ride to our city in 16 degr this morning though.

The temperature is very comfortable, the air pollution not.

Better we hadn't any idea of the situation?

iqair.com  vs. aqicn.org, it's a matter of taste...

today at 17:00:

iqair.com shows the AQI  186,             *** this is an index

equivalent to   124 ug/m3 PM2.5        *** this is a measurement

see:  https://www.airnow.gov/aqi/aqi-calculator/

**************************************************************

'a bit different'   https://aqicn.org/station/thailand/phrae-meteorological-station

AQI  117   ~   42 ug/m3 PM2.5

Confusing? - May be, different time, different place.
