Popular Post brommers Posted March 11, 2019 Popular Post Share Posted March 11, 2019 And where are the Mayor, the Governor and their officials at this time. Probably having yet another meeting in air-conditioned and filtered offices! The lack of any action is next to criminal neglect. 3 Link to comment Share on other sites More sharing options...
cmsally Posted March 11, 2019 Author Share Posted March 11, 2019 Talk about irony ! I saw this reading at about the same time a loudspeaker van came around announcing free health checks from the tesabahn!!! Go and have a look at cm108 facebook page. Lots of people reporting that people still burning. Link to comment Share on other sites More sharing options...
watgate Posted March 11, 2019 Share Posted March 11, 2019 (edited) I am speechless about how unbelievably toxic and poisonous the air currently is in Chiang Mai. I am wondering how many government officials who said they were going to crack down on the burning get up each morning in their air conditioned houses, travel to work in their air conditioned cars and work inside their air conditioned offices all day. All the while the masses are subjected to this disgustingly toxic and very dangerously unhealthy air. It is unconscionable how bad this situation is and when I read and hear about how chiang mai is supposedly rated one of the most desireable cities in the world I shake my head in disbelief.

ZeVonderBearz Posted March 11, 2019 Share Posted March 11, 2019 Government schools that one too. I am surprised they even take readings as I thought it'd be in the government's interest to keep it quite. Link to comment Share on other sites More sharing options...
Kelsall Posted March 11, 2019 Share Posted March 11, 2019 And there are still posters who think it's not that bad, nothing to worry about. Stay inside. 1 Link to comment Share on other sites More sharing options...
orang37 Posted March 11, 2019 Share Posted March 11, 2019 Thanks, CMSally, for your many informative posts ! Looking at today's 2.5 figures for the other CM locations on that site, I don't see any corresponding spike of the magnitude shown for this location. Any ideas about that reading ? ~o:37; Link to comment Share on other sites More sharing options...

Made worse in CM valley because of inversion layer and non windy conditions. 2 Link to comment Share on other sites More sharing options...

I am still interested in the significant variance (spikes) for that one location in CM compared to the other CM monitoring sites. Why does the AQI website list two Yupparaj monitoring sites, with the one you cite showing the much higher value ? cheers, ~o;37; Link to comment Share on other sites More sharing options...
cmsally Posted March 12, 2019 Author Share Posted March 12, 2019 If you look at the map (if positioning is correct), there are usually 2 Yupparaj monitors switched on. One inside the entrance, where there is a rather large tree and one nearer to the street (further north) which has less large tree cover. The positioning would make a difference. It would seem the more exposed one has higher readings. Again looking at the map , the one for CMIS is (according to the map) inside the school. Also a place with tree cover. It would be safe to assume this gives a fairly low reading compared to the environs. Also bear in mind they are out there with the water jets at 3 Kings and Tapae Gate. Not surprisingly Yupparaj gateway and Tapae gate are showing relatively low readings. I just drove past both and they have the water trucks out. 1 Link to comment Share on other sites More sharing options...
Berkshire Posted March 12, 2019 Share Posted March 12, 2019 The last few days have been the worst air quality I've seen in CM in quite some time. 2 Link to comment Share on other sites More sharing options...
canthai55 Posted March 12, 2019 Share Posted March 12, 2019 Bit off topic - Rode down to Li, in and out of the Nat'l Park, and back to CNX last week.

flare Posted March 12, 2019 Share Posted March 12, 2019 I'm guessing someone was sweeping near the particle collector and it read especially high (at least I hope that's the case): 1 Link to comment Share on other sites More sharing options...
TallGuyJohninBKK Posted March 12, 2019 Share Posted March 12, 2019 (edited) Any time the regional AQI map is showing dots filled with purple and dark/burgundy red, you know it's time to get out of Dodge.... or have a very strong/good air purifier indoors and stay there!!! The north region AQI levels yesterday and today are horrendous.... or to be more specific in terms of what the AQI system calls them, HAZARDOUS! The AQI danger rating doesn't get any higher than that! Edited March 12, 2019 by TallGuyJohninBKK Link to comment Share on other sites More sharing options...

Can anyone verify what the air is like in Hang Dong where the reading of 947 shows? Apparently the monitor is at Hang Dong hospital! Link to comment Share on other sites More sharing options...
flare Posted March 12, 2019 Share Posted March 12, 2019 I'm not far from the Night Safari- the air ain't what I'd call refreshing at the moment. Link to comment Share on other sites More sharing options...
Kelsall Posted March 12, 2019 Share Posted March 12, 2019 The above AQI 947 post raises a question: How high are these particle counters located? Near the ground, up 50 ft? Just wondering. Link to comment Share on other sites More sharing options...
flare Posted March 12, 2019 Share Posted March 12, 2019 It does seem pretty abberant- it's about 4x higher than anywhere else in the area at the moment. Link to comment Share on other sites More sharing options...

Thanks, It would be valuable to tease out from the data sources those which are comparable in terms of location factors; then you could examine what an anomalous spike means across comparable locations to, perhaps, generate other hypothetical causes/correlations such as air-flow patterns, traffic congestion around schools am/pm, etc. Wish I had a monitor here, near the Gymkhana Club golf course, to concretize my subjective experience of a very tangible drop in temperature and pollution coming into the moo baan. cheers, ~o:37; Link to comment Share on other sites More sharing options...

ChiangMaiAir has been offline since Friday(Hang Dong has not had numbers on Chiangmaiair for quite a few days so maybe error). Airvisual doesn't seem to have Hang Dong.

flare Posted March 17, 2019 Share Posted March 17, 2019 It was ~275 at the same location early this morning when I checked it before 6:00AM, so it's been updated in the last few hours- such a big increase in a short time is likely related to something other than the actual air quality (I hope...)

beautifulthailand99 Posted March 17, 2019 Share Posted March 17, 2019 (edited) Thailand has a huge army more Generals than any other country in the world and preventing some farmers from burning seems beyond their capacity. The words as chocolate and tea pot come to mind. In any civilised country this would be a national emergency. But sadly TIT. Sorry my font has screwed up.

TallGuyJohninBKK Posted March 17, 2019 Share Posted March 17, 2019 (edited) Most of the current readings on the AQICN site for the CM area seem to be reasonably current, anywhere from noon to 2 pm at the time I post this. http://aqicn.org/city/thailand/chiangmai---cmis/ The one 999 reading is either an error, or someone's lit a fire under or next to the sensor. In flipping thru a lot of the sensor readings for the region, Saturday/yesterday morning seems to have been very bad at many places with AQI readings exceeding 300 at many places and even 400 at some others. But today, those levels have come down to just being generally BAD.... instead of HORRIBLE. Edited March 17, 2019 by TallGuyJohninBKK 1 Link to comment Share on other sites More sharing options...
