Crowdsourcing: Stadium Shadows

A couple days ago, Tom Tango, did a study to show how hitters produced at different times of the day. One possible problem with the data is that shadows from the stadium could be skewing the data. We would like to know if at any time of the day there is a shadow between the pitcher and the hitter and from what time to what time does the shadow stay between the two combatants. Finally, if any one knows the information on any closed stadium, that information would be helpful.

With this information, it can be seen if the shadow has an effect on the hitter-pitcher match-up. I would expect the number of strikeouts to increase as the batter would have a harder time picking up the ball, but it would be nice to put a number to the theory. Thanks for your time and I am sure someone will jump right in for the data on Tropicana Field.
