Polar stratospheric clouds (also called Nacreous clouds) are distinct from ordinary Iridescent clouds: they only appear at high latitude regions, they form in the stratosphere, about 20 km high; they are made either of ice crystals, or of compounds of water and nitric or sulphuric acids.
The iridescence is the result of diffraction around those very small and homogeneous particles, just like in ordinary iridescent clouds and Coronae.
They are also distinct from Noctilucent clouds, which are typically 80 km high.
