Chiang Mai smoke season

Its the smoke season again and like previous years mountains are not visible from the Chiang Mai city. This is due to slash and burn that still takes place in northern Thailand as well as Burma and Laos.

update: We are back to normal good air, where PM10 shows under 50 (43.6 Monday 17th May). This year "smoke season" lasted almost 2 months from early March to early May.
