Insolation pt. 2

Incidentally, the plot I posted yesterday was only of the intensity averaged over the daylight hours. Multiplying by the hours of daylight (generated with the same program) should give the total amount of solar energy deposition per unit area in a day.

UPDATE This actually seems to give the wrong values, according to here and here. Maybe the NASA calculations are weighted differently than they say, or I'm misunderstanding what they mean. Either way, ignore this plot and use the values shown by those links.

The Dawn and Dusk criteria doesn't say explicitly if it's actual solar Dawn or that as "viewed" on location (which is modified due to atmosphere). Often weather channels report the "viewed" value. In conclusion, I don't know.
