Does there exist a Clear Sky Chart with the following enhancements?:
1 - Actual Cloud Cover (Offered Visually and not just Colors with a Legend, Over Time/Past & Predictive)
2 - Simulate/Predict Cloud Cover taking into account the direction from Observer to Observed Object and Angle of view - Close to the horizon (May be helpful to know when you can reasonably start/end tracking something you want to catch that night that is close to the horizon)
The reason I'm curious is:
A) I wonder if it's just not feasible for any/many reasons.
B) It would be great help to know this information.
In general, does anyone know of other Earth Weather, Clear Sky Clocks and Charts or anything else that gives more information?...anything related will be helpful.
EDIT: I would love to find this lecture "You can do better than Clear Sky Chart" mentioned: http://stjornuskodun.blog.is/blog/stjornuskodun/entry/966941/
