Hi

The earth is surrounded with atmospheric layers, which have different attribute and characteristic during day and night. refer to :http://ete.cet.edu/gcc/?/volcanoes_layers/

the density of the layers due to the variety of the temperature goes up and down which affects the penetration of the signal travelling through them.
