The speed series of this record contains a large number of
spikes that appear to be instrument errors. CMDAC has prepared
an alternate file in which the data have been smoothed in two
steps: First, many individual speed spikes were removed by
linear interpolation. Second, all of the time series (u, v,
and tempterature) were smoothed further by passing them through
a low pass cosine-lanczos filter. This filter removes completely
all frequencies higher than 4 cycles per day; frequencies lower
than 6.6 cycles per day are passed unattenuated.  Both the
original version of the record and the modified version are
available at this site.
