Our policy has been to include on this website only the original
measurements (when we have them) as opposed to filtered data.
In this case, however, we have substituted a low-pass filtered
version provided by the PI. In its original form this record has
a 15-minute time increment. The filtered series provided here
have a time increment of 3 hours. The passband is unknown to us
but does exclude the diurnal tides and higher frequencies. This
substitution was motivated by the presence of a great deal of
high frequency noise in the original record, particularly in the
v component. The noise appears to be the result of an instrument
malfunction. The high-frequency part of the original record is
not useful, and rather than provide data that might be
misinterpreted by the unsophisticated user, or exclude the
record entirely, we have elected to include here the filtered
time series.
