Where does the wind comes from today
(direction, speed)? And, how high are

the chimneys of Mae Sot?

Mae Sot/Tak is a lignite fired power plant,

so to say a dinosaur of this great but

antique technique.

AQI 95 Lampang - why AQI 95, no traffic!

AQI 112 Provincial Waterworks/Mae Moh -
no traffic at all

AQI 114 Phrae - no traffic.

No farmers burning, no industries.

No PM2.5 from India, nothing from China?

 

Btw, what's with all these 'Red Hospitals' up North?

But this might be another topic.

Did you ever visit Mae Moh? - It's a beautiful place.

And will stay for the next 30 years.
