Downwelling Shortwave Radiation:

Downwelling shortwave radiation is recorded on Kwajalein
Island using the same instrumentation used on TAO moorings
in the tropical Pacific and PIRATA moorings in the tropical
Atlantic.

Also included the shortwave file are time series of standard 
deviation and maximum radiation. Radiation has units of Watts 
per square meter and is measured at a height of approximately
3.0 meters above mean ground level. (Instrument height is shown 
as a negative depth in data files).

In the shortwave file, you will find data quality and
source codes to the right of the data.

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 to correct for 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 - 
    5 - Recovered from Instrument RAM (Delayed Mode)
    6 - Derived from RAM
    7 - Temporally Interpolated from RAM
