SeaState 2015, Fixed Riegl Lidar Wave Plots
BWB, Feb 5, 2016

This directory contains wave data plots from the fixed-beam Riegl lidar deployed
on the bow tower of R/V Sikuliaq for the SeaState 2015 cruise.

hourly_raw_riegl: hourly plots of the demeaned and despiked raw range measurements

hourly_spectra: loglog variance spectra computed from autocovariance and with the
    standard matlab psd function.  The latter is computed from a high-pass filtered raw
    data series (stopband = 0.04 Hz, passband = 0.05 Hz) with missing values filled by
    interpolation (pchip).  A Hamming window is applied in both cases.  The autocovariance
    method tolerates missing data but suffers from artifacts and low and high frequencies.

Hs: daily plots of 10-min significant wave height computed by 3 methods

missing: daily plots of the missing data count for each 10-min interval.
