This mostly means the clouds are pretty high. This is at a wavelength where methane is absorbing more than in the surface windows, so light does not reach the ground, but you're seeing stuff (clouds and haze) reflecting from somewhere in the troposphere. I think methane and ethane reflect very similarly at these wavelength (both are not very absorbing compared to the haze - but I could be wrong, can't find the data for ethane at this wavelength at the moment). A darkening at high latitudes probably means there's more haze or other absorbing stuff.

Everything you see is an albedo effect smile.gif
