This is a holding post. I wish to keep this sequence of posts on PCS together in a consecutive sequence. I have had some difficulties this week and have not been able to fully organize the data for presentation. The intent is to return and properly complete the post as soon as I am able.

The prior post asserted there exists significant seasonal variation in the exposure to solar UV radiation. Persons residing at 45 degrees North latitude are therefore likely to have minimal exposure to UV solar radiation during the winter photo-period. This post introduces a proxy for UV exposure and provides data in regard to a possible UV exposure deficiency.
