This would not explain the phenomenon for concrete, asphalt ...

comment Why wet is dark?
This explanation cannot be possibly true for the sand or soil - no fibers to bend on it.

comment Why wet is dark?
The answer sounds plausible, however there is one thing which is still unclear to me: why when the wet surfaces freezes it turns bright again (often even brighter than before)? Refraction index of ice is more or less the same as for water. Perhaps the the ice not filling the space in between the grains as liquid water did?

comment Why does the air flow faster over the top of an airfoil?
As the accepted answer (and the wikipedia animation) shows, it flows even faster than equal-time condition would suggest.

comment Is apparent horizon curvature lesser due to refraction of light in the atmosphere?
I understand your reply as: refraction makes Earth to appear 15 % larger (cf. mintaka.sdsu.edu/GF/explain/atmos_refr/dip.html), and the apparent curvature is affected accordingly. Can you confirm this is what you meant? That would make sense to me.

comment Is apparent horizon curvature lesser due to refraction of light in the atmosphere?
No, I am sorry, it is not (this is discussed in the question liked in more detail). It is almost flat, but not absolutely. A simple counterexample are NASA photos. Or do you want to claim there is some magical boundary at 199 km, above which the horizony is curved, but below which it is flat?
