Description: The home for finished/released addons.
I use numbers to keep scripts simple, I'm too lazy to write 12 words .you could name the alternate textures "Janurary", "February", "March" ... instead of "month-01", "month-02" etc.
The extra files are completely useless, on a Mac they are merged/hidden automatically. Next time I will use a non-Mac utility to zip.there seem to be a few useless files in the zip and a doublicate for MACOSX. Since I don't use MAC I wonder if that is necessary?
If you have opinions on what the specular parameters should be, please tell me and I will apply them, you are surely more authoritative than me on that. Other question: I use a specular map that is reflective on water; should there be some reflection also on ice?personally I use different specular parameters to make Earth look more realistic instead of the default Celestia ones, but I guess this is not directly related to your addon
I found two sources of sea ice data: Sea Ice Index and CryoSat.Oh and about the BMNG textures, I assume you know the place to download them. I only could find this version with polar sea ice But I don't like it very much. I discussed this matter with scalbers on this topic. Antartica is the same all months because there is only a short window for a satellite to map it during polar day and this data was probably just copied to fill the gaps during southern winter.

I plan to use the low spatial resolution data to generate a sea ice texture with an ad hoc program; the texture should change depending on the concentration somewhat, but for a first try a plain white should be fine.

The water mask agreed with altimetry so there still was a misalignment, which I solved with (b), but finally I switched using the water mask anyway because it was simpler to implement antialiasing along the coast.Maybe you can use a specular map as a mask to align the sea ice better with the continents? Of course there will still be some missalignement, but hopefully an improvement.
Virtual Textures are a nice touch, but only necessary at higher resolutions.
You might find this one interesting: I found a map of Earth's sea ice at 16k resolution!
