Does this kind of data say it all about the assessment of air pollution in CM .. and probably Thailand

Why the disparity in such a relatively small area of inner city and suburbs?

My thoughts as well, they put the monitors where high PM is expected to monitor same, usually high traffic areas, no point putting monitors where there is no pollution.

(unless there's a brown envelope involved :wink:)

And trees, which are very good at balancing climatic conditions in the rural areas.

Be aware, not all stations monitor the small particle pollution, so comparing one meter to another may be apples to ourselves m oranges.

 

The monitoring station near where I lived before I fled, stopped monitoring pm 2.5, and therefore gave what I can only call 'optimistic' readings, and then went down altogether.

PM 2.5 meters sensors are so inexpensive why rely on a sensor that is not at where you live or work.

 

Even a few meters can make a big difference in readings.

 

PM 2.5 Sensors are very portable so even if you're here for only a a few weeks or months you can take them with you.

I live in the lower part of the OPs Map and have a basic Xaiomi PM2.5 monitor in my garden and my readings consistently track within 1-2 points of the two nearby schools monitors that are shown on the OPs maps...

I've often noticed heavy smoke coming from a location an area area SW of that corner of the moat. Looks like a rubbish burn.

Can you recommend an inexpensive reasonably accurate sensor please,as I suspect there are very many inaccurate ones around?

It’s interesting to note that the UK Foreign Office website has recently been updated. It now specifically warns UK citizens of the poor air quality especially in both Bangkok and Chiangmai. Reading the advise it does not actually refer to the smoky season and, as such, visitors may think this is a year long problem. Wonder if this could lead to a reduction in the number of UK visitors or those looking to retire in Chiangmai?

Too much nit picking with these machines.

I just spent the past 2 weeks in CM it was beautiful.  Played golf just about every morning.

Some rain in the evening,  Seemed all clear and fresh to me thoroughly enjoyed myself.

Some need to live their life and move on...

The past two weeks have been clear— and have been Fine generally. Poster bkk6060 should have been here mid-February - May. Very serious pollution generally.
