Hi,

I am working on a program to simulate the exact appearance of each planet when given the Date/Time, camera pixel size, and focal length of the telescope. I think it would be an interesting feature to have it show the approximate size of the martian polar caps.

Does anyone know where data is available showing the date, and the latitude of the farthest extent of the martian polar caps? I was thinking it would be interesting to do a curve fit where X is the decilination of the sun as seen from mars, and Y is the latitude of the latitude maximum extent of the north or south polar cap.

Thanks for any help.

Kyle

This paper from 1953 provides some information that might help you, though you'll have to do a bit of work to put the results in the terms you specified.

Thanks, that looks like it may be useful. Does anyone know if the southern polar cap would change size at the same rate as the north one?
