Smoke, Smog, Dust 2014 Chiang Mai


Tywais

Recommended Posts

Thick, thick, thick. Today was the worse I have seen it this year. Heavy white haze all the way from Mae Hia to Chiang Mai University. At CMU could not see Doi Suthep temple.

PM10 at Yupparaj of 131, at City Hall 129. Max safe level is 120. Still not that high relative to previous years for this month. 172 at Lampang, highest in the country.

Yupparaj has seen 207 today, Lampang (38t) 232 and here in Phrae we had 304.

All aqmthai.com - What's the reason for our different results?

Btw aqicn.org shows CM 89, Lampang 134, Phrae 103.

Clueless.

Coming in from the north today, we thought CM was fairly clear!

Note that the standard figure is a daily average. That assumes that there will be many values higher than that, and many values lower than that. It doesn't matter too much in the example you gave as today's daily average will end up in the 120-130 region anyway, but it's important to keep this separate when comparing numbers.

I used the number on page one and didn't take the time to investigate the graph. It seemed the number was too low from what I was seeing. As WTK mentioned that first page number, 131, must be the running average.

Well, all the above is consistent with LOCAL burning with prevailing winds. Never mind Burma! And the Southern and far Northern reaches of the valley, let alone the province. These are NOT covered by the Doi Suthep - Pui FIRMS reports. This is a cumulative 2014 report that only includes large enough fires that happen to be alight during satellite passes. I have mislaid the 12 March report of 15 fires. I suspect that they reflected the same scene. A lot of the newer blazes seem to be forrest in origin rather than obviously agricultural burning.

Heading up to Doi Suthep this morning, will be interesting if I can see Chiangmai from up top.

No chance.....haven't even been able to see the airport runway since september from Doi Suthep.

Yesterday morning I was parked at the end of the runway, you couldn't see the other end and all the landing lights are on..... probably all day now.

You can't. Unless you go around 3pm, then you have a small chance. Thiss shouldn't come as too much of a surprise: if you can't see the mountain from town, you won't suddenly see town from the mountain. It's not rocket surgery.
