PM2.5 - this is the problem in Thailand.

Not AQI.

 

image.png.557a4ec9b06bca2892769f1a357f0b6c.png

https://www.iqair.com/thailand/bangkok

 

Phrae   PM2.5  114 ug/m3   -   AQI 181

CR        PM2.5    48 ug/m3   -   AQI 132 

CM       PM2.5     40 ug/m3   -   AQI 112

BKK     PM2.5      56 ug/m3   -   AQI 151

 

AQI often only seems to blur the real situation.

I would prefer released measurements of PM2.5.

Yet again , who to believe ?

 

ventusky.com is a great site. But not always correct. It is important to keep

in mind that the numerical model predicts the atmosphere in simplified form.

Better compare different sites all the time.

This is ChiangRai - Phrae at 18:00 (https://aqicn.org/here) while at  18:46 Lampang,

Phrae and Phayao (https://www.iqair.com/) were in Thailand's Top Ten, believe it or not.

May be this helps?   https://www.ventusky.com/webview/help.php

Phrae today between AQI 293 and AQI 322. - As often we don't smell it. 

But the horizon is grey, the air above bright-white milky. - The AQI-Calculator

will not calculate. Too much? - https://www.airnow.gov/aqi/aqi-calculator/

Really ?

At this point I'd rather believe Ventusky.

I went on my walk this morning and the sky was blue.

While not clean air , it was doable.

Yesterday , driving to Phrae city , I could make out the mountains , which I can't do at the numbers aqicn gives.

Yes.

But it's not a question of believe.

aqicn.org and iqair.com showed almost the same. Both wrong?

Once again, ventusky is a wonderful site, but it works with computer models

and projections.

Now it's 14:38 ICT.  Have a look at ventusky.com - today at 4 AM, 10 AM, 4 PM.

Next week there might be some rain !!

Let's hope so.

 

It's really worrying, five northern cities in Thailand's Top Ten,

today at 16:00.  -  If we include Mae Sot, Tak then six.

Then, an interesting read. Well hidden in the Cambodia Forum:
