Subject: | TWP/SMET/C1 - Upper winds failure |
DataStreams: | twpsmet60sC1.b1 |
Description: | The upper wind instrument was inoperative resulting in constant wind direction and speed. A failed cable was replaced. |

Subject: | TWP/SMET/C2 - Lower windspeed sensor questionable |
DataStreams: | twpsmet60sC2.b1 |
Description: | Lower wind speed sensor had degraded bearings. This sensor was reporting as much as 0.4 m/s lower values than the upper sensors when the winds were 2 m/s or below. The sensor was replaced. |

Subject: | TWP/SMET/C3 - Upper wind speed artificially slow |
DataStreams: | twpsmet60sC3.b1 |
Description: | The upper wind measurement was consistently slower by around 0.5 - 1 m/s than the lower wind measurement. The bearings on the upper wind measurement were binding. |

Subject: | TWP/SMET/C3 - ORG overestimated rainfall |
DataStreams: | twpsmet60sC3.b1 |
Description: | Optical rain gauge (ORG) measured approximately 10mm higher than two co-located tipping bucket rain gauges and a co-located disdrometer. The ORG is typically higher but usually not by an order of magnitude. |

Subject: | TWP/GNDRAD/C2 - Reprocessed: Incorrect calibration |
DataStreams: | twpgndrad20sC2.a0, twpgndrad60sC2.b1 |
Description: | The Gndrad PSP was changed out 11/25 but the datalogger program was not updated until 11/30. PSP #31293 installed 20071125.2202. Correct calibration coefficient = 123.46. Reprocessed to correct upwelling shortwave hemispheric irradiance (US) by: US(new) = (US(old) / 123.56 ) * 123.46 Reprocessing completed March 2008. |

Description: | The SKYRAD PSPs were changed out 11/25 but the datalogger program was not updated until 11/30. Reprocessed to correct calibration per: down_short_diffuse(corrected) = down_short_diffuse(orig) * (118.18/112.42) short_direct_normal(corrected)= short_direct_normal(orig) * (122.20/118.11) down_short_hemips(corrected) = down_short_hemisp(orig) * (133.16/137.57) Reprocessing completed March 2008. |
