Polar <strong>Stratospheric</strong> Clouds (PSCs)<br />
• PSCs first form as nitric acid trihydrate (HNO 3 . 3H2 O)<br />
once temperature drops to 195K.<br />
• As the temperature gets colder, larger droplets of<br />
water-ice with nitric acid dissolved in them can form.<br />
• PSCs occur at heights of 15-20km.
