There were no sondes launced during this period because there was
no helium on site and the hydrogen generator was not working.  The
hydrogen generator was repaired and launches resumed.

TWP/SONDE/C2 - Missing Winds
DataStreams:twpsondewnpnC2.a0, twpsondewnpnC2.a1
Description:
About half of the soundings in November-December exhibited drop-outs
in the winds.  These dropouts were typically over a depth of 1-2 km.
Sometimes the dropout occurred at the surface, sometimes at the top of
the sounding and sometimes in the middle.  These gaps occurred on:

TWP/C2  Installation
DataStreams:twpsondewnpnC2.00, twpsondewnpnC2.a0, twpsondewnpnC2.a1
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/SKYRAD/C3 - tracker inoperative
DataStreams:twpskyradC3.00, twpskyrad20sC3.a0, twpskyrad60sC3.b1
Description:
A lightning strike at Darwin removed the tracker from service.  Instruments installed on 
the tracker were rendered either inoperative or were not shaded during this time period.  
The longwave hemispheric instruments PIR1 and PIR2 appear to have been unaffected.  They 
are not suseptable to incorrect tracker operation.  The downwelling hemispheric shortwave 
PSP instrument mounted on Skyrad will not be affected by incorrect tracker operation.

TWP/SKYRAD/C3 - Solar Tracker locking at solar noon
DataStreams:twpskyradC3.00, twpskyrad20sC3.a0, twpskyrad20sC3.a1, twpskyrad60sC3.b1
Description:
The Scitech solar tracker from SGP that was installed on 2005-12-01 after the previous 
tracker was damaged by lightning on 2005-11-14 has been hanging up every day at solar noon.  
In Feb, the sun moved from south to north and the Scitech tracker does not seem to be 
able to deal with this. During this period the operators power cycled the tracker between 
05:00Z and 10:00Z almost every day and data from around solar noon (03:30Z) until the 
power cycle are unusable for the measurements that use the tracker (NIP, B&W Diffuse, and 
shaded PIRs).
The problem was corrected when the Scitech tracker was replaced by a Brusag
tracker on 2006-03-10.

TWP/SKYRAD/C3 - NIP Failure
DataStreams:twpskyrad20sC3.a0, twpskyrad60sC3.b1
Description:
Skyrad normal incident shortwave irradiance (NIP) started reporting impossible values for 
direct normal irradiance starting 16 November approx 2100GMT corresponding to a rain 
event at the same time.

The NIP was replaced fixing the problem.

Direct normal data are not recoverable.  However, the NIP data can be calculated from the 
global hemsipherical shortwave and global hemispherical diffuse datastreams by using the 
following relationship:
Global Horizontal = Direct Normal x cos(Z) + Diffuse Horizontal 
where Z is the zenith angle.

TWP/SKYRAD/C3 - NIP instrument failure
DataStreams:twpskyradC3.00, twpskyrad20sC3.a0, twpskyrad60sC3.b1
Description:
The NIP (Short Direct Normal) was replaced after it displayed symptoms of failure 
associated with either unknown precipitation related issues or a possible lightning strike.

NIP data are not recoverable.  Direct normal data can be reconstructed from global 
hemispheric and global diffuse data using the following relationship:
   global hemispheric = direct*cos(sza) + diffuse hemispheric

TWP/SKYRAD/C3 - Direct normal instrument failure
DataStreams:twpskyrad20sC3.a0, twpskyrad60sC3.b1
Description:
The NIP instrument (short_direct_normal data stream) failed giving bad data during this 
time period.  The failure start time coincides with a reported DC power failure but no 
connection between the reported power failure and the failure of this instrument could be 
determined. 

Ops also reported the tracker clock running 2.9 minutes slow during maintenance on 12/22 
0300GMT (see CS-2008-0714).  Again, the slow clock is not suspect and did not appear to 
affect alignment.

Ops replaced the NIP instrument on 12/30 and short_direct_normal data resumed normal 
operation.

Disregard the short_direct_normal (NIP) data during this time period or calculate using 
the global and diffuse instruments and the following relationship:
short_direct_normal = ((down_short_hemisp - down_short_diffuse_hemisp))/cos(zenith angle)

Subject:
TWP/SKYRAD/C2 - IRT Missing
DataStreams:twpskyrad20sC2.a0, twpskyrad60sC2.b1
Description:
After a significant rain event on 5/25, the IRT was found to be the cause of grounding 
problems with the SKYRAD datalogger that was affecting the measurements from other 
instruments. This problem was solved by removing the IRT signal from the datalogger. The problem 
was suspected to be with either the power/signal cable or the internal grounding of the 
IRT. The problem was corrected when both the IRT and analog cable were replaced on 6/23.
