Lawrence et al., 2012: DRAFT: JGR: Ambient Noise Numerical Evaluation average (STA) over 4s to long-term average (LTA) over 60s ratio (STA/LTA) greater than 2. We find that the number of detectable phases increases (23 %) as Ns decreases (1
Lawrence et al., 2012: DRAFT: JGR: Ambient Noise Numerical Evaluation The first and obvious scenario that fails to provide the correct answer occurs when the sources are confined or mostly in the near field (Δsx 16) and inaccurate estimates for simulations with fewer noise sources per window (Ns < 16). When the incoherent noise level is below ~1, the accuracy is sufficient to recover accurate attenuation. Within these two confines, there is little trade-off between these parameters for a wide range of dimensions values. Ultimately, a combination of the proposed source configuration is more plausible than any individual one. We therefore created case that evenly draws from the four source 13
