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 |

Description: | On Jan 3rd approximately 1000GMT the effects of a tropical cyclone started affecting the
installed radiometer measurements at ARM/TWP/C3(Darwin) - both Skyrad and Gndrad. On Jan
4th 0740 GMT the Gndrad station was shutdown to avoid damage due to the close passing of
this storm. Station was restarted Jan 7th 0515GMT. |

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) |
