I am trying to make volumetric clouds for a planet, I have a cloud sphere with a thin solidify modifier applied to it and a volume scatter material. How can I make it transparent where the the clouds arent? http://www.pasteall.org/blend/31681
I kinda got it working by plugging the image into a multiply math node. multiplied it by 1000 and then plugged that into the density. But it only works using generated or object texture coordinate inputs.

I don’t think that you need the transparent, just the right quantity of density. Also the image texture is 2D while the generated textures are 3D, or volumetric by nature.
