Although lightning has a broad-spectrum emission, its noise power increases with decreasing frequency.
Therefore, at very low frequency and low frequency, atmospheric noise often dominates, while at high frequency, man-made noise dominates in urban areas.

I think atmospheric noise depends on frequency as the main thing for the external noise is to choose the optimum frequency to eliminate as much of the noise as possible.

It shouldn't be affected by frequency since it is caused by natural disturbances.
