North of Phrae there is a blinding sun, the sky blue/grey. - PM2.5  33ug/m3 or  AQI 95.

This is    image.png.3972b8b230aaf0b5df2ee64e15c6bc4f.png

People with respiratory or heart disease, the elderly and children are the groups most at risk.

 

I take the numbers -if correct- as a warning.

Do you have an PM2.5-meter?

In addition to my own observation it calms me down.

e.g.  Unlike manual harvesting, mechanised harvesters leave stubble and rice paddy straw in the field. Disposing of crop waste is time-consuming. After harvesting rice, farmers get only a short window to plant winter crops such as wheat and rapeseed, and late sowing means lower yields.
So farmers find it much cheaper to burn the residue, which accounts for about a quarter of air pollution.

 

 

Please, don't forget:

Anything above 60 is considered unhealthy.

60 ug/m3  correspond to an AQi of
