Particulates

Atmospheric aerosol particles, also known as atmospheric particulate matter, particulate matter (PM), particulates, or suspended particulate matter (SPM) are microscopic solid or liquid matter suspended in Earth's atmosphere.

Tropospheric ozone

Ozone (O3) is a constituent of the troposphere (it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer).

1930 Meuse Valley fog

The 1930 Meuse Valley fog killed 60 people in Belgium due to a combination of industrial air pollution and climatic conditions in December that year.

1948 Donora smog

The 1948 Donora smog was a historic air inversion that resulted in a wall of smog that killed 20 people and sickened 7,000 in Donora, Pennsylvania, a mill town on the Monongahela River, southeast of Pittsburgh.

1997 Indonesian forest fires

The 1997 group of forest fires in Indonesia that lasted well into 1998 were probably among the two or three, if not the largest, forest fires group in the last two centuries of recorded history.

2005 Malaysian haze

Haze is caused by "hotspots" (zones with high temperature levels as seen via satellite imagery) in Malaysia and Indonesia.

2006 Southeast Asian haze

The 2006 Southeast Asian haze event was caused by continued uncontrolled burning from "slash and burn" cultivation in Indonesia, and affected several countries in the Southeast Asian region and beyond, such as Malaysia, Singapore, southern Thailand, and as far as Saipan; the effects of the haze may have spread to South Korea.
