Yes you are right. I was thinking that the difficulty is in
determining a "standard image" containing all the value you can find
in a meteo image (clouds, snow, land, sea ....).
Because it is problematic to find an image including all the features
and to be used as template with respect to its histogram.
For example I cannot choose a cloudy image or a cloud free image as
template because in this (extreme) case the histogram will be affected
by this.
Am I correct??

I hope I was able to describe better my doubt and now it is clearer!!

Cheers,

titan
