Noctilucent cloud - Wikipedia
WEBNoctilucent clouds (NLCs), or night shining clouds, [1] are tenuous cloud-like phenomena in the upper atmosphere of Earth. When viewed from space, they are called polar mesospheric clouds (PMCs), detectable as a diffuse scattering layer of water ice crystals near the summer polar mesopause.
Polar stratospheric cloud - Wikipedia
WEBPolar stratospheric clouds (PSCs) are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are best observed during civil twilight , when the Sun is between 1 and 6 degrees below the horizon, as well as in winter and in more northerly latitudes. [ 1 ]
