Pollution Control Department – New website with daily pollution data
Folk who have the luxury of deciding where and when to go who take the air quality into account may be relieved to know that for the 30 days to 16th January 2012 the Upparat school in the centre of old Chiang Mai had the lowest average PM10 – fine particulate – readings in the 7 years of records to date.

These records may be viewed at the old PCD website . However data at this site ends at 31st January 2012 and for both current and earlier information we must now use the NEW Air Quality Monitoring site. The list of pollutants monitored appears above and the colours indicate the level of danger according to the government standards which are well below UN recommended exposure levels. e.g. for PM10 the UN recommends 50 ppm the Thai government 120 ppm.
The new site has Thai names with English legends and figures are latinised arabic. The Upparat school station is No 36 , Chiang Mai Sala Glang No 35 & Lampang No 37.
There appear to be some teething problems and also the pollution meters we installed at OurChiangMai.com are no longer functioning. Hopefully all will be running smoothly in the near future.
Thanks! I was wondering what had happened to the old pcd.go.th site, as they hadn’t updated their data in several weeks. I’m fairly impressed with the new site, though I don’t see the transliterations that were mentioned in this post. Is there a link somewhere that switches between the Thai and roman scripts?
Sorry Drew, I can see no option for Roman text and I hav difficulty with many of the names. I suggest we ask PCD to dom some more work on the site.
Meanwhile i notice Ozone readings ar in teh red at Rayong with its industrial polution problems and สถานีตำรวจภูธรหน้าพระลาน has deadly PM10 readings. However I would ask anybody who knows where this station is to let us know please.
Disgusting air quality already and it’s only February. Chiang Mai is not a good place to live. I can’t wait to leave!
