Yes, since UV rays are a component of sunlight.

Yes, in fact the relative UV content is higher although I don't know why.

Yes, and that is where ozone holes are. They WERE shrinking.

Yes, anywhere the sun shines (that means the entire planet), there are ultraviolet rays, and a sunburn and/or skin cancer risk.

Roger the Mole

Yes, more than elsewhere when the sun is up.
