Fascinating question in it's implications.
If the atmospheric noise (which, particularly at night, might not be the
dominant source) were uniformly distributed (source direction/polarization)
then the effect would be solely that on the desired signal. However, I'll
bet that the noise is NOT evenly distributed either in angle of arrival or
polarization, so both the SNR and received signal strength might vary.
