The international definition of fog is a visibility of less than 1 km (3,300 ft); mist is a visibility of between 1 km (0.62 mi) and 2 km (1.2 mi) and haze from 2 km (1.2 mi) to 5 km (3.1 mi). Fog and mist are generally assumed to be composed principally of water droplets, haze and smoke can be of smaller particle size.
Arctic haze is the phenomenon of a visible reddish-brown springtime haze in the atmosphere at high latitudes in the Arctic due to anthropogenic [1] air pollution. A major distinguishing factor of Arctic haze is the ability of its chemical ingredients to persist in the atmosphere for significantly longer than other pollutants.

Midnight sun, also known as polar day, is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight. When midnight sun is seen in the Arctic, the Sun appears to move from left to right.
A blizzard is a severe snowstorm characterized by strong sustained winds and low visibility, lasting for a prolonged period of time—typically at least three or four hours. A ground blizzard is a weather condition where snow that has already fallen is being blown by wind.
Each classification affects visibility and ground movement due to accumulation and is quoted below: [45] Light snow – Visibility is equal to or greater than 5 ⁄ 8 mile (1,000 m) in falling snow. A trace to one inch (2.5 cm) per hour accumulates. Moderate snow – Visibility is 5 ⁄ 16 to 1 ⁄ 2 mile (500 to 800 m) in falling snow. One to ...
In meteorology, visibility is a measure of the distance at which an object or light can be seen. The main article for this category is Visibility . Subcategories
Snow goggles (Inuktitut: ilgaak or iggaak, syllabics: ᐃᓪᒑᒃ or ᐃᒡᒑᒃ; [1] Central Yupik: nigaugek, nigauget) are a type of eyewear traditionally used by the Inuit and the Yupik peoples of the Arctic to prevent snow blindness.
