LAMPANG, Feb 26 – Haze in this northern province on Sunday has caused flight delays from low visibility of some 400 metres, the lowest since January.
Head of Lampang Meteorological Station, Tiwa Panmaisi, said unusual climate conditions forced the morning flight from Bangkok to Lampang Airport to land in Sukhothai province to wait and see about the situation before it could resume its flight later.
On Saturday, the visibility was around 800 metres, while dust particles were measured at 200 microgramme/cubic metre, higher than the safe standard of 120 microgramme/cubic metre, he said.
Meanwhile, in Chiang Rai, dust particles have remained higher than the normal rate for several days, with low visibility of about 500 metres, forcing Mae Fah Luang-Chiang Rai International Airport to turn on runway lights for safety reasons.
Fire trucks were used by Chiang Rai Municipality to sprinkle water in the hopes of easing particulate density.
