Abstract:

The report discusses some additional applications of K-line spectra to the LASA short-period noise analysis. Two summer noise samples were processed to complement the work performed previously on eight winter noise samples. In addition, an experiment was conducted to determine if significantly better results could be obtained using 21 min of noise instead of 7 min to estimate the statistics. The principal conclusions are summer noise appears to be quite similar to winter noise at LASA except at the microseismic peak, any processing results gains very probably can be extrapolated across seasons and using the long noise sample did not give more interpretable wavenumber spectra.
