Cloud Cover: Everything You Need To Know

What is cloud cover?

Cloud cover is the fraction of the sky celestial dome covered by cloud. It is measured in eights, also known as oktas, according to the World Meteorological Organization (WMO).

When viewed from space, cloud cover is called polar mesospheric clouds (PMCs). They are detectable as a diffuse scattering layer of water ice crystals near the summer mesopause.

Polar stratospheric clouds (PSCs) are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft).
