What component contributes to the intense color of Nacreous Clouds, differentiating their composition from NLCs?
Answer
Their composition involves nitric acid and water to form ice crystals in the stratosphere.
Nacreous Clouds (PSCs) are chemically more complex than NLCs, involving nitric acid and water to form ice crystals, which, combined with their extreme illumination angle, produces their vivid coloration.
