The black line is the total response of "white cloud".  Then you can see the response curves of the individual Red, Green and Blue  pixels:



Plus there are lots of dips for the various Fraunhofer lines ...

Lots of absorption lines for all the crap in the atmosphere too

Methane, carbon monoxide, you name it and it's probably superimposed on there somewhere !

Fraunhofer A - the Oxygen line at 760nm is quite pronounced.  It seems to indicate oxygen must exist somewhere

Interesting that the pixels have almost identical response in the IR beyond 800nm.
