Thin and wispy Cirrus clouds are the most common high-altitude cloud and can be found at altitudes of 8-17 kilometres from the surface of the Earth.

Western University expands use of meteor cameras to track contrails and tackle aviation-induced climate change ...

Astronomers have observed thick, mineral-rich clouds, potentially containing iron, enveloping the young exoplanet YSES-1b, leading to the possibility of iron rain. The YSES-1 system, only a ...

Ice crystals floating in a high, thin layer of cirrostratus may allow blue sky and nighttime stars to shine through with minimal obstruction. A cumulonimbus cloud thick with water droplets, though ...

Cirrus clouds at the level of the jet stream – often about 6 miles (10 kilometers), above the ground – can sometimes move at over 200 miles per hour (320 kilometers per hour).

The high-altitude cirrus clouds are thought to reduce heating during the day by blocking some sunlight, and prevent cooling at night by keeping infrared energy from radiating away into space.

Noctilucent clouds over the Baltic Sea, as seen from Germany in 2019. Typically seen in polar regions, the clouds are increasingly appearing at mid- and low latitudes. Matthias Süßen via ...

Thanks to data from the SPICAM Ultraviolet and Infrared Atmospheric Spectrometer onboard Mars Express, a fleeting layer of clouds have been discovered at an altitude between 80 and 100 kilometres.

Meteorologists attribute this phenomenon to the presence of high-altitude cirrus clouds over the city. These clouds contain ice crystals that scatter sunlight, creating the halo effect observed.
