Smoke, Smog, Dust 2015 Chiang Mai

Recommended Posts

The last satellite map I saw of the fires were almost none in Burma - they were all to the East of Thailand.

I like to use NASA's Firms for its real time view:

The picture does look pretty good at present, both Myanmar and Thailand seem fairly subdued, I wonder why.

EDIT: Cambodia looks busy, I suspect that's affecting Pattaya?

It always seems to get bad after they start burning the forests for mushroom growth. Have seen very little burning in the hills on mountain bike rides, and that is probably as there is still a lot of moisture up there from the late season rains. Some of the creeks are still running quite high. A few more days or weeks of hot sun and the conditions should be prime for local burning and smoke which will drift downhill at night into the CM basin.

is this a good sign or is this the same as every year? http://www.chiangmai-mail.com/current/news.shtml "Air pollution levels remain stable in Chiang Mai as the government begins implementation of burning bans for the province starting February 15, 2015 and increased surveillance of pollution and hot spots for 60 days."

i was originally planning on going to Chiang Mai with a baby in mid march but am thinking if its to dangerous

Can't see Doi Sutteph today. I'm guessing it's really the start of it for this year. :(

Ememkay, if you have other options I'd consider them. (Or get yourself an air filter and filter fabric over your a/c for baby). If second hand cigarette smoke is bad for kids... imagine what this is doing! You're fine again once the rains start... The air is so much better then.

The headline is misleading as air quality is anything but stable. As of mid-February we are approaching daily averages of 100 µg/m3 PM10 in Chiang Mai. The haze is visible and you can smell it. How well the implementation of the burning ban is going to work this year remains to be seen. Personally, I don't have high expectations after having observed complete failure for almost a decade.

Don't come to Chiang Mai in mid March if you don't have to, because air pollution usually peaks around that time.

Cheers, CM-Expat

We're telling you what we think, based on our experiences living here. That's not the same as trying to evaluate numbers (that are manipulated) on a screen... (I've heard that they hose the data equipment with water to reduce the number - true or not, who knows - but it wouldn't surprise me in the least!)

You won't know how bad it is until you experience it for yourself... So if you've booked the flight already, come, guage it, and be prepared to leave if you don't like what you find. The loss then will be outweighed by the 'knowing'...

Alternatively just Google it. There will be, I'm sure, loads of posts describing it in throat scorching, lung-searing, eye smarting detail. It really is unpleasant, and if I had the opportunity to be somewhere else at this time of year, I'd be there. I'd have been in the plane yesterday when I could no longer see Doi Setteph mountain!

for some reason this doesn't seem worse than the rest of the world except for the states (world map http://aqicn.org/nearest// )

which of the numbers really make a difference?

im currently visiting here http://aqicn.org/city/jerusalem/ and while the number is not to far off, its definitely clear and crisp air

It is not very bad yet in Chiang Mai as the visibility is still over 8 kilometers. Most years, it gets so bad that visibility is reduced to 300-500 meters for several days. I went through old photos and the visibility is usually fairly good until the third week in February when it seems they start burning the forests in earnest. By the time March hits, visibilities are much less than what we have today. There seems to be pretty fair correlation between visibility and the PM-10 particulates which are unhealthy. I normally stop cycling when the PM-10 levels get around a 100 uG/cubic meter but we have not hit that yet this year. You can almost always count on the first two weeks of March being quite bad.

Here is a very good research publication that goes in to great detail of the contributing factors for the smoke season and the primary locations. For those who doubt the contributions from neighboring countries, the details are pretty clear in the document. It is a 67 page paper but you can scan key indicators easily in it. It has pictures too. biggrin.png

This year has been a whole lot better than the same time last year. Went up to Mae Ngam dam today and had lunch with some friends. Slightly hazy but not too bad; could see one fire to the Southeast but that was it. Last year at this time you'd be lucky to have 5km visibility.

Here is good research paper another TV poster provided last year that should be on the reading list as well. The effects of burning start on about page 299.

Mountain biking on the forest trails around Chiang Mai, there is an obvious lack of humus mass on the forest floor as everything gets burned off year after year. You have to get to rather remote areas before you start to see the natural soil conditions of a tropical forest.

Tywais, with all due respect, exactly what details are clear regarding the contribution from neighbouring countries?

The PDF consists of several papers, of which only the first seems to be related to the smog, so please correct me if I am wrong.

At 11 pages, it is a quick read, but I do not see anything quotable in those pages regarding the contribution from neighbouring countries. There is nothing that quantifies what part of the problem experienced in Chiang Mai is caused by neighbouring countries, except some useless references to firemaps showing that there are fires not only in Chiang Mai, but also far away. So what? How much of the pollution from those far away fires reaches Chiang Mai?

If, before you read that paper, you had no idea whether one percent or 90 percent of the smog we will now experience in Chiang Mai is pollution blown in from neighbouring countries, you will, as far as I can understand, after having read that paper still have no idea. I still have no idea.

I would not say it is a very poor paper, but it is obviously some sort of student paper, perhaps an assignment part of an early or mid-level university course related to agriculture. Unlike some of the posters here, who in a retarded way blame the farmers for only caring about themselves, the paper does however show an understanding for that it is not simply up to the farmers to stop burning. The government must first provide them with an adequate alternative to burning.
