... conditions. This was achieved via amplitude modulation of the provided boundary condition (BC) spectra over space and time using a single factor with a log-normal prior probability density function having mean of 1 and a standard deviation of 0.15. The standard deviation was chosen based on numerical...

Outlier removal routines use the standard deviation of the time-series which itself could be biased from errors. Therefore, a method to compute unbiased...
