2.  Clouds are aesthetically appealing &
add excitement to the
atmosphere, without them, there
would be no
rain, snow, thunder, rainbows or
lighting.
 CLOUD- visible aggregate tiny water
droplets suspended in the air.

3.  Climate change
 Cloud cover
 Cloud optical thickness
 Cloud top properties
(temperature, pressure/height).

4. HIGH CLOUDS
• Cirrus (Ci)
• Cirrostratus (Cs)
• Cirrocumulus (Cc)
LOW CLOUDS
• Strartus (St)
• Stratocumulus (Sc)
• Nimbostratus (Ns)
MIDDLE CLOUDS
• Altostratus (As)
• Altocumulus (Ac)
CLOUS WITH VERTICAL
DEVELOPMENT
• Cumulus (Cu)
• Cumulonimbus (Cb)

5. High cloud: Cirrocumulus
(small, round, white puffs)

6. High cloud: cirrostratus (halo)

7. Clouds with vertical development:
cumulus (floating cottons)

8. Low cloud: stratus
(resemble fog but not
reach the ground)

10. •Orbit equator same rate as
the earth.
•Remain about 36,00km
above fixed spot on earth
surface.
•Monitoring specific region.
•Use “real time” data
system.
Geostationary
Satellite

12. • Complement the geostationary
Satellite.
• Scan from north to south.
• Photographing clouds directly
beneath them.
• Provide sharp picture in polar region.
• Circle earth at much lower altitude
(~850km)
• Provide detailed photographic
information.
Polar Orbiting
Satellite

17. • senses reflected solar
(sun) radiation that
has a wavelength of
0.52 to 0.75
micrometers
• Show the sunlight
reflected from cloud’s
upper surface.
• Advantage?
• Disadvantage?

19. • Satellite sensed energy
as heat.
• Often colorized to bring
out details.
• Warm low clouds
radiate more energy
(dark)
• Cold high clouds (light)
• Advantage?
• Disadvantage?

22. CONCLUSION
• A cloud is a visible mass of condensed droplets or frozen
crystals floating in the atmosphere above the surface of the
Earth or another planetary body.
• Clouds represent an important factor in the recycling of the
important greenhouse gas water vapour from the planet
surface to the atmosphere and back again to the surface.
• Evaporation of water removes heat from the planet
surface, and represent an important cooling process.
• Clouds also can be divided into four groups which are
high, low, middle & vertical development clouds.
