Here is a neat website ... you can click on the various satellites and see its view of earth: http://fourmilab.ch/earthview/satellite.html

 

I am struck by how few clouds are shown. Is there some kind of filter in the cameras that remove them?

I dont believe its the ACTUAL view from a satellite, i think its just a program that you input the orbits and what not, and will show you the view as if you were there.
