wolfmuc..... Check out post #120 on this thread for a major contributor. Some of those sites you graphed also have local sources like coal-fired electric plants.

Thanks T_Dog, local sources might be an explanation.

Will try to find out the nearest power plants when the internet

is a bit faster than today.

Check out #120? - Didn't find this 'major contributor'.

Burning up in the mountains to open up farm land and to improve mushroom production is a major cause of our smoke. Tywais has a pinned link at the beginning of this thread and also on post # 120. Here it is again, and it shows the active fires in Asia.

T_Dog, thank you for the answers. - Maybe it's slash&burn too, but I don't think predominantly.

If you would have a look at this site

http://earth.nullschool.net/#current/wind/surface/level/orthographic=-254.09,20.00,295 .

As I see it there might be a circuit of winds, blowing the haze from Beijing, Shanghai

and Hong Kong via the north of Vietnam even into Thailand.

http://aqicn.org/map/ shows the air pollution in Asia conveniently displayed, yet the results

for Thailand seem to be too low. - But there might be another route (south-west) for the haze

coming from Beijing as I noticed the last weeks. Of course based on the results of that site.

But all the same, it's really bad here in Phrae province.

And it's not the farmers burning their fields.

Rode up the cable car to the highest point in the Langkawi Is. group just over the S border and at 700m ASL the horizon had a noticeably brown tinge in all directions, even though at sea level the viz is excellent.

More local observations: There are some new (FIRMS) instances of blazes which appear strongly to be agricultural burning on a north-south line from Rte 1095 (Mae Taeng-Pai Road) about 20km west of Rte 107 to somewhat north of Samoeng.

What is missing, comparably, this year to last ---so far --- are many agricultural fires in a close radius around the intersection of those two roads.

And the incidence of blazes appears to have dropped considerably within the same time frame. Of course, it ain't over until it's over.

In looking at the attachment, I should note that FIRMS misses a lot, and the coordinates seem consistently skewed to the East a couple of hundred meters. These eyes in the sky miss a lot, especially the small stuff.

Otherwise, there seemed to be a rather distinctive (and unfamiliar) odor in the Muang Chiang Mai air this morning, not a wood/rice straw smell but something different. Anyone else notice that?

This website has not been noted much lately. Some people may wish to follow it.

Notice the general SW pattern of the winds which are very much consistent with monsoon patterns year after year. I think you'd have a difficult time making a persuasive argument correlating seasonal pollution here with industrial pollution in Northern China. The barometric effect contributing to a high pressure "lid" is a different matter.

Incidentally, it is the Japanese who got furious with the Chinese (not just about property rights to rocks in the Sea of Japan or the East Sea (take your pick!) but wind-blown air pollution, as I recall from last year's press. That indicates Westerlies typical, I believe, of those latitudes. Here we have the seasonal SW monsoon toward Southern China, not the reverse.

The Japanese can't complain about jacksh1t, with all the radiation circulating the Pacific......

This remains a fascinating thing every year.. By relative virtue of being stuck in a hospital room this week I've had a near continuous view of the mountain, with not much else to do.

It's interesting that there was a big dip in visibility (spike in haze) around noon. And then a dramatic clearing up afternoon. (Mountain completely disappeared from view for me around noon). Then I look at the figures from the Yupparaj measuring station (in town) and it matches that exactly:

post-64232-0-03381800-1394191606_thumb.j

And now I can see trees and separate ridges again. It's just remarkable how it can come and go like that in a matter of an hour or two. And again, this is absolutely nothing yet compared to how bad it can get. I think we'll end up at a daily average of about 80 ug/m3

In the hospital, and no view! Except to keep your eye on the nurses, of course!

Get better!

Been here 7 yrs and this seems to be the worst year ever. Never before have my eyes watered or been red, never before has my wife coughed so much or even me. Before you could always make out Doi Suthep if you looked hard but now you can't. What happened to the law enforcement clamp downs they have been promising for 7 years, things are getting worse not better.

Really? That is contrary to most reports / observations.

Out in the countryside it's been hazy for nearly a month, but I would put this down as a good year. Relatively, though.

IMHO it's cr@p at the moment.

Maybe I guess it comes down to which way the wind is blowing. Out Sansai, Sansainoi way it is hell.

I'm sure you're right with 'which way the wind is blowing'.

It all depends to be at the right place, right time.

In Phrae province it is really bad; never in my life I had problems breathing.

Tonight I had to cancel 2 phone calls from friends, not enough air to speak.

And really, this is neither joke nor hysteria.

^ Yeah, Phrae and Lampang don't look so good. Several days over the Thai unhealthy limit.

That's not good news for Chiang Mai typically, as we get it a bit later.

Of course Lampang typically shows worse values than Chiang Mai, so perhaps we'll be looking at moving into the 100-120 range next week.

On the other hand, Chiang Rai and Mae Hong Son still show very good values, with Mae Hong Son also exceptionally clear.

Amazing how it changes around the valley. This morning, out east of San Kamphaeng it was awful. Yesterday, it was bad in the morning, but cleared up in the afternoon. There is a lot of construction going on in this area, very dusty. Also, very smokey at night (can smell it). Often a layer of smoke visible in the morning.

Yes, indeed, radioactivity is really a much more serious problem in some ways and not a problem to be solved in any way so easily as the general air pollution problem. And that is genuinely scary! But, in my view, your post is a cheap irrelevant shot. We are not chatting about the very,very serious radioactive issue in Japan, a very serious issue indeed; we are talking about something else, my friend. Why make such cheap points ?!

Please remember that there are local neighborhood conditions, other less local conditions, not so local conditions, regional conditions, broader areal conditions and the whole frickin' planet atmospheric conditions to consider! Get real!

What's the old saying from the '70s? "Think globally; act locally." A rather relevant slogan. Do what YOU can do. Yes, that is not much, probably, for people who post here (the most self-centered cyber-complaint postbox that I have ever known: "I need...!," "I want...!," Can you tell me where...?" "Can you help me...?!), but one thought might be to moderate our individual demanding selfish materialistic way of life which --- surprise, surprise! --- requires much more energy, such as electricity for our air cons or petrol to get to Promenada (or a demand for reliable shuttles to get to Promenada from city center when that is pure selfishness!)

Really!

"Think globally; act locally" is an expression of individual thoughtfulness and personal action that may indeed be part of a larger answer. Yes, my protestation here is lovably "naive," if you wish to wish it away in that way. We in Chiang Mai aren't going to save the world, but we can do our very small bit part. I have seen very, very, very little on this forum that concerns more than personal poster interests plus a lot of humor (?), ethnic and generally cheap shots. There is a lacuna very empty of considered thought. Isn't that more than a bit sad?! Sorry, I forgot pizzas, hamburgers and box wine!

Sometimes, ThaiVisa Chiang Mai (probably true elsewhere in this well-devloped and marketed cyberspace, but I don't hang out) is very informative and helpful in general discourse (if you have the patience and wisdom to ignore the dross). ThaiVisa Chiang Mai can really be helpful (sometimes too often in ways it seems too many posters lack much capacity to help themselves) in some very practical ways. Unfortunately, it seems, in some ways, that is not always so. But we do have to remember that ThaiVisa is a commercial enterprise, and that poses problem from time to time for both ThaiVisa and those who post in it. Self-discipline more than moderator discipline is needed! The concern, ultimately, it sometimes seems, of ThaiVisa is with its broader legal liability, a valid concern in a culturally sticky environment. Lawyers are costly, in any case!

I have obviously rambled on! But of no damage to anyone! And it is, after all, late! Sleep well!

You'll recall who bad it got yesterday, Friday,March 7. No wonder. Eleven more fires reported by FIRMS on that date. Remember that the eyes in the fires don't see it all. This screenshot reflects all reports so far this year.

Good heavens we're blessed this year.. Normally I wouldn't even be outside when not absolutely necessary (or be in the North for that matter) when into the second week of March..

Now look at it.. (Ang Kaew)

Now, this was the clearest part of the day in the early afternoon, but it's still remarkable especially noting that the weather looks fairly normal otherwise.

Long may it last.
