On several occasions, large (10 percent) differences between the global

relative to the direct flux reported by the PSPs.  These occurences
persisted for several days each time and are likely due to salt on one
or more of the radiometers.

TWP/SKYRAD/C2 - Nauru solar tracker
DataStreams:twpskyrad60sC2.a1, twpskyrad60sC2.b1
Description:
During Reset7 (8/6) the skytracker firmware was upgraded for Y2K.  While still 
at the site, the mentor noted that the tracker was sticking and replaced it on 
8/8/99. The replacement tracker also failed.  Repeated attempts through 8/13 
were not successful.  After 8/13, the tracker was not operational.

It was found that the problem was the result of bugs in the Y2K compliant 
version (2.44) of the firmware.  On 10/14, Jeff Zirzow installed a new 
tracker with the Y2K non-compliant version (2.43) of the firmware.  It was
correctly assumed that the Y2K issues would only be apparent at the
19991231-20000101 time boundary.

Exact times of changes are not known; noon GMT (midnight Local) was used to
adequately window the time period of the changes.

TWP/SKYRAD/C2  - IRT incorrect min/delta values
DataStreams:twpskyrad60sC2.b1
Description:
For field sky_ir_temp, the value of valid_min was incorrectly assigned to -49.7 C and no 
value of valid_delta was assigned. The actual values should be -60 and 50 C, respectively.

TWP/SKYRAD/C2 - IRT affected by rain or shutter
DataStreams:twpskyrad60sC2.a1, twpskyrad60sC2.b1
Description:
During this time period, the SKYRAD IRT data was affected by rain
events due to a shutter which was installed to protect the optics
from being emersed in rainwater.  While the shutter was closed, or
if water got on the lens, the IRT data was invalid.  If water did
get on the lens, the contamination usually persisted until an
operator cleaned the optics.

The configuration of the IRT was changed Oct 29, 2001.
The IRT was mounted such that the field of view is directed
downward at a 30 degree elevation angle and reflected
to the vertical by a front-surfaced, gold-plated mirror.
This configuration prevents rain from directly striking
the lens and collecting in the lens barrel.

Data from 11/98-2/99 were examined and times when the
data are invalid are identified below.	Data from 3/99-10/01
also contain periods of invalid data, but it is left to
the data users to identify those periods and filter the
data according to their needs.
