It's gone from very bad to even worse !

Can't go out . Luckily I have an airpurifier but my dumpf.ck cats insist to go out and want to keep the door open.

This should be the best season with great temperatures but totally ruined by this bad air.

Perhaps a cat door with a photoelectric barrier might help?

I'm sure there are members on ThaiVisa with a lot of ideas.

It depends on time and place, a bit difficult.

Your #1   AQI 108     -     PM2.5  38

#2 is Rongkwang Hospital in Rongkhem:

AQI  141   should be  PM2.5  about 50

#3  Ventusky  13:00   PM2.5  51 ug/m3  ~  about AQI  142

and at our place now:  PM2..5  49  0  AQI  136

All not too different.

[FlorC]

IQAir always shows less than the others.  (now 83)

aqicn shows more. (now 136).

 

When I go walking into the backland , I see a lot of rice fields (and some corn), that are going to be burned .

Even the place where I stay , burns some garbage , they just don't care. (and yes there is garbage pick up once a week).

 

Although Phrae has no corona , it's a good excuse to wear a mask , so you don't stand out as a pollution nut with a mask.

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

No aircon or even a fan needed in the car.

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.
