Description:
On April 1, 2001 at 00:00:00 new data header with consistent variable naming
conventions, etc were to be used for all sites, all data streams.  At the TWP
sites the time of the movement to the new convention did not occur precisely at 00:00:00.  
The following data files contain between 40 seconds and 20 minutes of data from 4/1/02 
in the old format.  The delayed format change did not affect data quality in any way.

TWP/C2  Installation
DataStreams:twpmfrsrC2.00, twpmfrsrC2.a0, twpmfrsrC2.a1, twpmfrsrC2.b1
Description:
The Nauru ARCS was installed during the period September-November
1998.  Data were being collected by the end of October, but for the
first several weeks of November, the site was undergoing considerable
change, so data from that period should be used with caution.  The
official site dedication occured on November 20.  Most on-site
activity ended following the dedication so we will consider November
20 to be the beginning of the Nauru operations.  The last members of
the installation team left Nauru on November 24.

TWP/MFRSR/C2 - Shadowband Misalignment

Description:
During these two periods, there was a shadowband misalignment on the Nauru MFRSR.  The 
shadowband alignment was adjusted several times during this period:  on May 17, May 24, June 
10, and June 28.  The shadowband motor was also replaced on June 28 (all dates 2005).  
During the flagged periods (May 1-17, June 2-28), the misalignment resulted in significant 
noise and occasional biases in the direct and diffuse irradiance variables.  Optical 
depths derived from this instrument will also be of poor quality during this period.

TWP/MFRSR/C2 - Instrument failure
DataStreams:twpmfrsrC2.b1
Description:
The mfrsr on Nauru failed. It was found by the observers to be rotating continuously. It 
has been stopped and restarted twice to no avail. Problem seems to be associated with the 
contoller/logger board that was replaced during RESET visit 16-26 Sept. The board that 
was replaced is on route to Darwin. Spare board and motor needs to be sent by mentor to 
Nauru. Spare board $9CC1 installed by observers.

TWP/MFRSR/C2 - Head not level
DataStreams:twpmfrsrC2.a0, twpmfrsrC2.a1, twpmfrsrC2.b1
Description:
The data from the Nauru MFRSR is questionable because either the cosine correction
is bad and/or the head was not level.  These problems cause some total optical
depths to be below the Rayleigh limit ... obviously something is wrong!  The
head was checked for level on 1999/05/12 and it was found to be out of level
so we do know that 'levelness' has been a problem.  We don't yet know if the
cosine correction, too, has been a problem.  In any event the head was 
changed on 99/06/19 and the data from this point on looks very good.

TWP/MFRSR/C2 - Estimated calibration errors
DataStreams:twpmfrsrC2.a0, twpmfrsrC2.b1
Description:
The Nauru MFRSR data has been examined for the dates of about 1999/06/21 through 
1999/07/22.  The head temperature is stable, and there's no sign of shading problems.  The 
calibration stability was examined through the use of Langley regressions, and the calibrations 
seem stable and reasonably accurate, to wit:

wavelength     estimated calibration error (negative means MFRSR is too low)
415                -1.6%
500                -1.2%
615                -0.2%
673                -0.6%
870                 0.6%
940                 don't know but probably with 1-2%

Keep in mind that these estimates are from a time period of about 1 month's duration and 
they could change as we receive more data.
