Unhealthy Smoke Over Thailand

For more than a month, northern Thailand has been experiencing unhealthy, elevated levels of smoke and air pollution. The thick haze is a result of wildfires and prescribed burning by farmers clearing their land for the planting season. Meteorologists expect the unhealthy air quality to last into May.

This image shows smoke and haze blanketing portions of southeastern Asia on April 12, 2019, as observed by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. At 9 a.m. local time on April 12, Thailand’s Pollution Control Department reported that nine provinces were experiencing “unhealthy” or “very unhealthy” air quality—notably around Chiang Rai and Chiang Mai, which is surrounded by mountains that trap the pollution in the area.
