It would seem to have to thin a LOT to match the effect of the Earth's tilt away from the sun, which is what really decreases the solar radiation during winter months.

Thanks for giving this question a stab.
I live in Switzerland with loads of cable cars nearby. When people get sick of the cold and grey, it is very common to just jump on a train or cable car nearby and pop above the clouds within 30 minutes and be in brilliant sun and blue sky. Then spend the day walking out in the sun before descending back below under the bad weather.
I thought perhaps this might pertain equally to people who go skiing in the Rockies.
The question for people badly Vita D deficient, are you really getting Vita D by planning a winter trip to the mountains in the Northern Hemisphere?
