April 30, 20179 yr What's up with the AQI measurements? How can CMIS report 8 when City Hall is reporting 100? Supposedly on FB there are pictures of people spraying the air around the measurement devices with mist before readings are taken, but still the numbers are askance. Nice to see the mountains, but maybe they are fake.
May 1, 20179 yr I have noticed aqi anomalies and it nearly always happens at weeekends when some of the stations are closed like schools, city hall. Basically the last accurate reading maybe on Friday and the next accurate reading is on Monday. That's my assumption.
May 1, 20179 yr One more measurement-point, Prem Centre is North of Mae-Rim ... http://aqicn.org/city/thailand/chiangmai/maerim---prem/
