Ice polar stratospheric clouds (nacreous clouds) form at temperatures below the ice frost point, typically near −85 °C, which is colder than the average lower stratosphere temperature.The characteristic bright iridescent colours, resulting from diffraction and interference of light waves, suggest that the clouds are composed of similarly sized spherical crystals of about 10 μm in diameter.
