FlorC Posted January 21, 2021 Share Posted January 21, 2021 It's gone from very bad to even worse ! Can't go out . Luckily I have an airpurifier but my dumpf.ck cats insist to go out and want to keep the door open. This should be the best season with great temperatures but totally ruined by this bad air. 2 Link to comment Share on other sites More sharing options...

Perhaps a cat door with a photoelectric barrier might help? I'm sure there are members on ThaiVisa with a lot of ideas. Link to comment Share on other sites More sharing options...

Your #1 AQI 108 - PM2.5 38 #2 is Rongkwang Hospital in Rongkhem: AQI 141 should be PM2.5 about 50 #3 Ventusky 13:00 PM2.5 51 ug/m3 ~ about AQI 142 and at our place now: PM2..5 49 0 AQI 136 All not too different.

FlorC Posted January 22, 2021 Share Posted January 22, 2021 IQAir always shows less than the others. (now 83) aqicn shows more. (now 136). When I go walking into the backland , I see a lot of rice fields (and some corn), that are going to be burned . Even the place where I stay , burns some garbage , they just don't care. (and yes there is garbage pick up once a week). Although Phrae has no corona , it's a good excuse to wear a mask , so you don't stand out as a pollution nut with a mask. I enjoyed the ride to our city in 16 degr this morning though. No aircon or even a fan needed in the car. Link to comment Share on other sites More sharing options...

The temperature is very comfortable, the air pollution not. Better we hadn't any idea of the situation? iqair.com vs. aqicn.org, it's a matter of taste... today at 17:00: iqair.com shows the AQI 186, *** this is an index equivalent to 124 ug/m3 PM2.5 *** this is a measurement see: https://www.airnow.gov/aqi/aqi-calculator/ ************************************************************** 'a bit different' https://aqicn.org/station/thailand/phrae-meteorological-station AQI 117 ~ 42 ug/m3 PM2.5 Confusing? - May be, different time, different place. **************************** Link to comment Share on other sites More sharing options...
