Thank you for your light discussion...

I have a question about the light emitted form the sun (peak) and
reflected from a full moon (peak). How much brighter is the sun at noon
day at the equator, on either the spring or fall equinox than that of
the reflected light of a full moon (when every it is most intense).

In lumens per square foot is it close to?:

            Sun = 10,000 lumens per sq/f.
            Full Moon = .03 lumens per sq/f.

And what percentage of solar radiation is reflected or absorbed by the
earths atmosphere?

I have searched high and low for these stats. Can you help?

Thank you
