Subject: | TWP/SKYRAD/C3 - tracker inoperative |
DataStreams: | twpskyrad20sC3.a0, twpskyrad60sC3.b1, twpskyradC3.00

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. |

Subject: | 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. |

Subject: | TWP/SKYRAD/C3 - NIP instrument failure |
DataStreams: | twpskyrad20sC3.a0, twpskyrad60sC3.b1, twpskyradC3.00
|
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 |

|
Subject: | 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) |

to normal operation.
The affected data streams are short_direct_normal (NIP) and down_short_diffuse_hemisp
(8-48).
The down_short_hemisp are not affected.
The down_long_hemisp1 and 2 (PIR1 and PIR2) should not be affected but direct sun can
affect individual instrument performance. |
