Winds:

Included in your files are zonal and meridional components
of wind, wind speed, and wind direction.

Winds use the oceanographic convention, so that a wind with 
zonal and meridional components of 1.0 and 1.0, is blowing toward 
the Northeast. Wind components and wind speed have units of meters 
per second while direction has units of degrees, clockwise from
true north. For example, a wind with a direction of 90 degrees
is westerly, i.e., directed to the east. Daily averaged wind 
speeds and directions are based on daily averaged wind velocity
components.

In ascii format files, to the right of the data, you will 
find data quality codes for wind speed and direction.

Using the Quality codes you can tune your analysis to trade-off 
between quality and temporal/spatial coverage. 


Quality Code Definitions:

0 = datum missing

1 = highest quality; Pre/post-deployment calibrations agree to within
sensor specifications.  In most cases only pre-deployment calibrations have
been applied

2 = default quality; Pre-deployment calibrations applied.  Default
value for sensors presently deployed and for sensors which were either not
recovered or not calibratable when recovered.

3 = adjusted data; Pre/post calibrations differ, or original data do
not agree with other data sources (e.g., other in situ data or climatology),
or original data are noisy.  Data have been adjusted in an attempt to
reduce the error.

4 = lower quality; Pre/post calibrations differ, or data do not agree
with other data sources (e.g., other in situ data or climatology), or data
are noisy.  Data could not be confidently adjusted to correct for error.

5 = sensor or tube failed

Source code definitions:

    0 - No Sensor, No Data 
    1 - Real Time (Telemetered Mode)
    2 - Derived from Real Time
    3 - Temporally Interpolated from Real Time
    4 - Source Code Inactive at Present
    5 - Recovered from Instrument RAM (Delayed Mode)
    6 - Derived from RAM
    7 - Temporally Interpolated from RAM
