DOI: 10.1785/0220160137

Abstract: Self‐noise estimates from spectral correlation analysis of ambient noise data recorded synchronously by three accurately coaligned broadband seismometers have become a de facto standard for comparison of instruments and assessing their performance. Nonetheless, many of… read more here.
