Weather Satellites
  
   _I know nothing about these: need to find some info._
   
   The Meteosat GOES amd GMS weather satellites operate in geostationary
   orbits. That is to say, they orbit the Earth at the same speed as the
   Earth's rotation, thus constantly viewing the same area. This means
   that their temporal resolution is effectively unlimited, so they are
   able to generate the familiar weather 'movies'.
   
   They are, however, of limited use for (other) remote sensing purposes.
   Geostationary orbits (more typical of communications satellites) are
   constrained to high altitude, and to the equator. Thus good viewing
   angles over high latitudes are not possible. The very large area
   images are at low spatial resolution; the best achieved by Meteosat
   and GOES is 2.4Km (?).
   
   Here are a few pointers to weather pictures online, or see the
   Meteorology Resources FAQ for a far longer list.
