Chiang Mai's air quality has improved after rain on Saturday helped clear days of haze. Officials were hopeful that things would return to normal if there was more rain. Five haze-tackling measures would also be implemented including sending royal rainmak
Prayat Ananpradit, acting head of the Chiang Mai Natural Resources and Environment Office, said yesterday that particles smaller than 10 microns (PM10) in Chiang Mai were measured at about 100 micrograms per cubic metre, better than Saturday’s reading of 282 micrograms, which was also the peak in the northern province this year. The safe PM10 level is 120 mcg.
