Bangkok air quality hits hazardous levels

Air pollution in Bangkok reached hazardous “red” levels in two districts on Friday, as toxic PM2.5 dust exceeded safety standards in 43 provinces across Thailand, prompting authorities to ramp up cloud-seeding operations. In response, the Department of Royal Rainmaking and Agricultural Aviation has intensified “atmospheric piercing” techniques, deploying additional flights to spray dry ice and cold water to disperse the smog.

Aeronautical Radio of Thailand is supporting the mission by coordinating five flight rotations daily across outer Bangkok and surrounding provinces, including Samut Prakan and Samut Sakhon, to mitigate the impact on public health.
