Remote Sensing Applications

• METEOROLOGY

Remote Sensing Applications

• Meteorology
• First application of satellite remote sensing
• Began with TIROS1, launched in April 1960
• Simple TV system on board to map clouds
• Satellites are now a vital an integral part of
  our weather forecasting system.

Remote Sensing Applications

• Meteorology
• Now both polar orbiting and geostationary
  satellites are used
• Polar orbiters operate in a similar way to other
  remote sensing satellites (Landsat, SPOT etc.)
• Geostationary satellites continually view the
  same portion of the Earth.

Remote Sensing Applications

• Meteorology
• Polar orbiting satellites
• Main satellites are the NOAA series (currently
  15)
• Direct descendants of the early TIROS spacecraft
• Instruments include the AVHRR and TOVS

Remote Sensing Applications

• Meteorology
• NOAA
• Major instruments
• AVHRR - already discussed
• TOVS - TIROS Vertical Sounder

Remote Sensing Applications

• Meteorology
• NOAA
• Major instruments - TOVS
• Uses multiple channels on the edge of an
  atmospheric window
• The spectral position of the channel then
  determines the altitude of the reading
• Processing provides data on atmospheric
  temperature, moisture and total ozone.

Remote Sensing Applications

• Meteorology
• Geostationary Satellites
• Orbit above the equator at 35,800 Km and complete
  one orbit every 24hrs.
• Remain over the same point on the surface of the
  Earth.
• Continually view the same portion of the Earth.
• A network provides coverage of the entire globe

16
Remote Sensing Applications

• Meteorology
• Geostationary Satellites
• Australia mainly uses the Japanese GMS (5) series
• Other satellites in the network include the
  American GOES series and the European METEOSAT
• Australia also gathers data from the Chinese Feng
  Yun 2 spacecraft.

Remote Sensing Applications

• Meteorology
• GMS
• Spin stabilised with the spin used to step the
  scans via a small tilting mirror
• Main instrument is the VISSR
• One band in the visible (1.25km res) and three in
  the Infra red (5km res)
• IR channel 3 is targeted at water vapour
