I will share in end Feb/Mar detailed near real-time satellite photos by ASMC showing hotspots and smoke columns from them, and also visible images.

They have been extremely valuable from our experience here in a Singapore forum in predicting haze etc.

In-depth documentary about the Indonesian haze 2015

1-hr and 8-hr breakpoints (PM2.5 ug/m3 concentrations) for Unhealthy, Very Unhealthy and Hazardous Health Advisories. See if you'd wanna follow this type of shorter term health advisories.

This has been very valuable to us, because the haze levels here in SG was extremely volatile at times. We could not afford to wait 24hrs for the official AQI Health Advisories.

Sharing these documentaries too, pretty interesting. Quite applicable to Thailand haze as well.

The 3M shop on Wulai road sells 3M N95 masks in bulk, both child and adult sizes.

Hey bro, I remember you having the dylos and also the 2 x Blueair 650.

In 2015 after I stopped posting in the thaivisa thread, it became clear that the Indonesian haze is going to be very severe due to the El Nino signals (sea surface temps, El Nino atmospheric index etc). Procured a lot of toys. biggrin.png

In the video are 2 Chinese air purifiers (one of which is controllable from your mobile phone via cloud and WiFi, really cool) and a Samsung AX40. 3 laser particle counters from China (gotten from taobao). Unfortunately, there is no easy way to buy such stuff from Thailand.

BTW, I found that the 3M Filtrete airconditiong filter is not very effective at high concentrations of haze (eg > 100 ug/m3 PM2.5) and also if your house is leaky.

Also, we found that all measurement equipment, be it optical (laser particle counters) or BAM (Beta-ray Attenuation Method) monitors need to stabilise the intake RH % at 35% in order to be accurate.

You can DIY heat up the air, but for our china-based particle counters, we just apply a % conversion factor for convenience. When compared to the official data, we can get pretty close.

This is how our govt measures it, intake air is pre-heated before measurement.

Without RH % compensation at the intake, pretty close to the pros.

MetOne BAM 1020. I think it costs USD30k.

I was in Kalimantan in October 2015, the situation was terrible, you could not see 50 metres at times

I read recently, that the Indonesian Government have followed Singapore lead and hit Companies who burn with large fines

Its about time the ASEAN countries got serious, and stopped these Companies burning each year

Its simple hit them hard...LARGE FINES AND / OR IMPRISONMENT

The cost to the people health and countries runs into millions

Sounds good to me. How much of it is caused by large companies here in Chiang Mai?

The main perpetrators are the landowners themselves, the rich elite and their associates.

Heavy fines on landowners has worked in other countries but this lot are hardly likely to fine themselves. 1503456.GIF

Smokey in CM today.
The smoke I see is looking mostly to the east and south from around the CMU area.

Can't see much past Kad Suan Kaew and the eastern mountain range is not visible at all.

Any folks out past the city 12+ kilometers smoke free?

Maybe it's the car exhaust fumes from all our unwanted visitors, heading back to Bangkok.

I think this is smoke from crop burn off.

That's a very good question, and one of the first to ask.

As I recall, one very large company, CP, is now "working" with the government on a campaign to mitigate burning, and the target there is primarily corn. The place to start looking, outside of rice production, is probably the biofuel and feedstock agribusiness companies.

My hunch is that while some large tenent-farmed tracts (as with rice production) may be owned by some companies but that there are more contracts made ultimately with small to medium-sized middlemen and growers. This no doubt complicates new and existing regulation and enforcement.

Not that some progress isn't being made more generally with improving recognition of the problem and changing peoples' attitudes. Just to pick a local example, look at TV Chiang Mai where, years ago, there was a persistent group of posters who denied being personally affected by air pollution! This parallels the change of attitudes (and later customary behavior and laws) regarding smoking tobacco. And then there were some who got into rather pointless lengthy presentations of information about whether or not things were better or worse in Chiang Mai over the years! We haven't seen those kinds of posts in recent years, but the number of posts asking where to buy face masks and air purifiers has increased quite a bit.

Good post. One thing to note is that mountainsides where no farming is being done are ALWAYS torched by the locals for hed top mushroom generation. A single person could light miles and miles of fire lines in a single night. Some years up in Mae Taeng, the coverage was close to 100% in the jungle trails in the mountains where we mountain bike.

Except the last part a decent post - just scroll back to 2015 post and you will find this useless and lengthily discussions.

This evening the headman in our village announced that the government is asking for villagers to complete all agricultural burning by February 15. After that, fires will by monitored by satellite and the gov't will "take action" against communities that violate. Time will tell.

They will have no Problem to see the red belt as usual and as usual they will ignore it.
