Multiple coherence gives a quantitative measure versus frequency of how well a linear combination of n input channels can match the n 1st channel in a seismic array. If the inputs can match the output exactly, then the multiple coherence is unity and only n channels for short period noise fields at UBSO and TFSO. The multiple coherence of the noise at UBSO and TFSO short period, vertical component arrays is high greater than 0.9 over the microseismic frequency band. The decay of the multiple coherence of the noise with increasing frequency is faster at TFSO than at UBSO and faster at UBSO than at LASA.
