AQI getting higher again... over 100 in some places today.

This might happen every now and then.

Just a look from Oct. 2019 to May 2020 - Chiang Mai - CMIS  PM2.5

So, did you check your air purifier already?

I think, everything is already said. - So only my two screenshots from today.

The first (ventusky.com) seems to me a bit exaggerated. But who knows?

On 26 October a fire was recorded North of the city that is a rice field area.

Not that anyone is paying  attention, but satellite coverage revealed anther fire (They have to be substantial.) is this same area on 6 November.

... at least today there shouldn't be any fires?

Chiang Mai is about in the center

Starting in earnest, playing golf this morning the smell of burning was coming from 2 or 3 different directions.

 

Time to form a committee and talk about it!

Reporting for the 3d time, there are satellite reports of fires North of the city.  So, this time, here is a photos of the rice fields near Mae Faek with the coordinates.

Well tell them to put their fags out.  It is a greens area after all!

A happy new year to you all on this fourth day of the year. The air pollution is back with a vengeance, there is a strong smell of biomass burning and the AQI in my area is at 159 - Unhealthy - and the pm2,5 reading is at 71,3 which is almost fifty percent above the Thai danger level. The question is which mask to wear, the virus one or the pollution one!

[markcm19]

soon they will form a committee to talk about what they will do this year in regards to the burning, and of course it will be nothing, as usual.

As a matter of interest,  which AQ recording station are you referencing?

May be?

There are so many problems in Thailand these days.

 

But:  no support regarding air pollution.

(usually)  You can't see it.

Chiang Mai: A hell of pollution started again and anybody do nothing for resolve the ANUAL BURN SESSION.
 

Are these guys in power too busy building a rocket to the moon with 3 billion Bath?????

 

Are they looking for a place in the moon with free pollution zone? ????

Same procedure as every year?

But to be fair: near CM (in the center) you

only can see three fires in the last 24hrs.

 

Our neighbours are more active.

Poor grammar notwithstanding, I assume you reside somewhere other than the city environs?

CM city and immediate suburbs have no major pollution, just the dust from 2 months of no rain, and vehicle exhaust fumes.

You may wish to lobby Government to ban all vehicles and invoke rain dances otherwise the current situation will only worsen while the drought continues and vehicles help stir airborne particles.

I am sorry to disappoint you with my grammar, although I speak other languages, English is not my native language.  I also assume that you have perfectly understood my words, I don’t need Your criticisms and after a few years writing in Thaivisa, is the first silly and malicious comment about my grammar. Focus on the OP issue and write with a little more propriety and not how I write my words.

 

About the high pollutions level; Chiang Mai have the honor to have the worst air in the world... Number one.????

It seems also, that you have no idea of the real cause of pollution in the North of Thailand. Not only the cars makes high levels of pollution. Or the dust in dry season as you say.

Living in North Chiang Mai more than 10 years, surrounded by farmers and neighbors who burns their plastics, garbage and plantation fields every days, burning their forests in the natural park where I reside, chemicals  for rice and vegetables plantations and above all, the winds that bring pollution from China or Burma.

I was not criticising.  The poor grammar use made it difficult to analyse your intent and sincerity, especially in context with mention of moonshots and billions of 'baths'.  The latter could be put to good use in extinguishing fires .... no?

 

I too have lived here for over 10 years and studied 'smoke and pollution' in great depth which produced accurate data which I've shared in this very thread on previous occasions.  If you go back to some of my earlier posts you may find them of interest.

 

You say you live in north Chiang Mai "surrounded by farmers and neighbors who burns their plastics, garbage and plantation fields every days, burning their forests in the natural park where I reside, chemicals  for rice and vegetables plantations and above all, the winds that bring pollution from China or Burma"

That sounds terrible.  Have you spoken with your Orbitor, Tessaban or Amphur office about the burning of plastics and forests?  Down here in Chiang Mai the local authorities act on most genuine complaints fairly fast.  We make a point of getting 2 or 3 neighbours to complain also, thus it's seen as a larger problem ... one time they sent the fire brigade out to extinguish a rubbish fire ... overkill, but it stopped the villager from burning again.

 

Most of Chiang Mai, Chiang Rai gets smoke from Burma (and further west) a little later in the season.  Mae Hong Son also contributes to that.  I'm unaware of any pollution coming from China as that would require northerly winds.

 

Government agencies and NGO's are slowly educating Thai farmers in methods other than burning although it will likely never be a total success owing to topography which precludes the use of machinery to plough chaff under.

 

Our dry season creates DUST.  Vehicles, wind, construction, farming and almost every human endeavour exacerbates the dust problem.  HEAT causes the dust to rise and mix with vehicle exhaust fumes .... way more dangerous than vegetation smoke, and at times tinder dry bush catches fire and creates major smoke haze.  Not much we can do about those situations.

The rain and wind really cleared things out. Morning constitutional, fortified by coffee, in a blustery wind with a bit of a chill, wow. An absolutely sparkling morning as the sun rose. If only we could get another three day blow next month.

It's almost like you are blind and have no sense of smell either.

 

Nearly every farmer burns their fields here in CM, and most of the woodland and forest is also set on fire each dry season.

 

Most villagers are out sweeping up dry leaves and making piles of them and garden waste every few days and burning them. Other poor people collect plastic waste and burn it every morning, together with waste from mucking out their cow shed and other junk.

 

It's also common for people to be dumping building waste, old clothes, plastic etc out in the countryside and hills, which is also set on fire.

 

I see all this every year for 14 years in CM.

You let McTavish live for a month not knowing  he was blind, and had no sense of smell ?"

I could smell smoke this morning, wasn't invasive, though Doi Suthep is almost obscured and general visibility down to ~ 8 km.  Normal for this time of year.

This can be anything. PM2.5 not necessarily smells.

But not good?

Here is a small table from this morning, Chiang Rai Forum:

3.  Phrae         76  /  162

4.  ChiangRai  60 / 153

5.  ChiangMai 54 / 146

Sorry, Bangkok. Only

PM2.5   29  /  AQI  86

 

At night everywhere much 'better'.

At night Chiang Mai, San Kamphaeng nr. 8 in TH

This might change the next hour:

                 *******************

[Yom]

The air from northeast seems to be ok, while NW winds might

be very bad.  -  Anybody knows the situation in Myanmar?

 

A further explanation for the high AQI levels up north could

be the power plants Mae Moh/Lampang and Mae Sot/Tak.
