  1. 1. REMOTE SENSING & GIS (MMS 3005) Sarjana Muda SaIns (Sains Samudera) REMOTE SENSING APPLICATION: CLOUD OBSERVATION GROUP MEMBERS: CHONG WEI SHENG UK27672 FITY SUSANTY HAWANG UK27680 NOR ADHAFATIHAH ZAINAL ABIDIN UK28187
  2. 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. 3.  Climate change  Cloud cover  Cloud optical thickness  Cloud top properties (temperature, pressure/height).
  4. 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. 5. High cloud: Cirrocumulus (small, round, white puffs)
  6. 6. High cloud: cirrostratus (halo)
  7. 7. Clouds with vertical development: cumulus (floating cottons)
  8. 8. Low cloud: stratus (resemble fog but not reach the ground)
  9. 9. •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
  10. 10. • 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
  11. 11. • 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? Visible Photograph
  12. 12. • Satellite sensed energy as heat. • Often colorized to bring out details. • Warm low clouds radiate more energy (dark) • Cold high clouds (light) • Advantage? • Disadvantage? Infrared Clouds Image
  13. 13. SATELLITE
  14. 14. 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.
