Synthetic ambient seismic noise dataset for testing ambient-noise methods

Abstract

We present a continuous seismic waveform dataset created with the rotated staggered-grid finite-difference simulator HeidimodX (Saenger et al., 2000). The aim of the dataset is to recreate the random nature of ambient seismic noise using numerous synthetic point sources with arbitrary source parameters and locations. Three-component waveforms are recorded at the free surface of a three-dimensional model with two different velocity structures. This dataset can be used to benchmark and test robustness of different methodologies typically applied to ambient noise data.
