DAILY MAX WAVE displays the largest wave (measured crest-to-trough) recorded
by a buoy or a pressure sensor over the course of 1 day.
The height of each wave passing the sensor is defined as the difference
between the max and min values between consecutive zero down-crossings.
Time series from directional buoys are not edited; incomplete
and otherwise problematic sections of the time series are discarded.
(This can result in days without any 'largest wave' value recorded,
even though the days in question may have extensive spectral and
displacement data available.) Pressure sensor series pass through CDIP's
standard editor and are detrended prior to the max wave calculation.
(Note: Values from 2007/05/17 to 2007/10/23 were calculated from up-
crossings, not down-crossings.)
The output is a four-column table:
Date: The UTC day, the 24-hour period examined
Time: The UTC time at which the largest wave was recorded
Largest wave: the height in meters of the largest wave
Period: the time elapsed between zero down-crossings for the largest wave
