Hi all:

I don't have the time to comment on the rest yet, but one is pretty  
easy. The solar constant is defined at a distance from the Sun of 1  
A.U. which is the semi-major axis of the Earth's orbit, so in away it  
is already averaged for the variation of the Earth's distance from the  
Sun over one year. If there is one thing scientists dislike is a  
"variable" constant! ;-)

QUESTION: Should not the solar constant be referenced to mean d^2
where d is the distance from earth to the sun ?
