[QUOTE="Topper, post: 438624, member: 186250"] Ah you mean as in tropospheric propogation, well of course the answer is no as the signals do pass through the troposphere however since microwave radiation is attenuated by moisture and the moisture content of the air normally tends to decrease when the sun sets (as the moisture is deposited as dew on the ground) one would think that the answer would be better reception at night however if I am not mistaken the troposphere also shrinks at night to compensate for this reduced moisture content so the status quo appears to be maintained. In reality I would have thought it extremely difficult to extract meaningful measurements as such since there are far too many variables involved including such things as continuous atmospheric pressure changes coupled with bi-annual equinox changes constant temperature changes and continuously varying cloud formations.
