Subject: | 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. |

Subject: | TWP/GNDRAD/C3 - IRT malfunction |
DataStreams: | twpgndrad60sC3.b1 |
Description: | The internal IRT power supply failed (probably due to a lightning strike on 11/14) and was drawing excessive current on the data logger's DC system. The problem was corrected by replacing the instrument with a spare. |

Subject: | TWP/SKYRAD/C3 - IRT damaged |
DataStreams: | twpskyrad20sC3.a0, twpskyrad60sC3.b1 |
Description: | The analog output of the IRT was damaged by a lightning strike. The problem was corrected by replacing the instrument with a spare. The damaged IRT was returned to the vendor for repair. |

Subject: | TWP/GNDRAD/C3 - IRT power |
DataStreams: | twpgndrad60sC3.b1 |
Description: | The IRT failed to report after a planned power outage to add lightning protection modules to the AC power wiring. The problem was corrected when a loose power connection to the logger was found, rectified, and power restored to the logger. |

Subject: | TWP/SKYRAD/C3 - Reprocess: Longwave Calibration error |
DataStreams: | twpskyrad60sC3.b1 |
Description: | Modified pyrgeometer calibration procedures were implemented beginning in December 2003. These modified procedures introduced a calibration bias in the longwave data. The previous procedures were re-implemented at all sites between December 2005 and February 2006 to restore proper calibrations. The data collected while the incorrect procedures were in place are being reprocessing to remove the calibration bias. Note, this also affected standard deviation, maximum and minimum data fields. |
