Clouds – from both sides • Stratus – the low clouds (0-5,000 ft) • Composed mainly of water • Indistinct appearance • Reflects much light in visible satellite pictures • Looks ‘warm’ in IR
Clouds – from both sides • Cumulus – the vertical clouds (2-50,000 ft) • Composed of water below and ice above • Sharp appearance • Looks like cells in visible satellite pictures • Can look like bulls-eye of cold in IR
