Subject: | TWP/SMET/C3 - ORG data noisy due to degraded ground |
DataStreams: | twpsmet60sC3.b1 |
Description: | SMET Rain Data began to be noisy during December 2005 and the problem slowly became worse over time so that in February 2006 the ORG was reporting with a constant background value of around 0.10 mm/hr rain rate. ORG voltage showed a near constant value above the 85mV threshold. The ground for the ORG had become degraded and was lost due to corrosion. |

Subject: | TWP/SMET/C3 - Reprocess: Windspeed2 calibration error |
DataStreams: | twpsmet60sC3.b1 |
Description: | The lower anemometer was replaced afer being removed in anticipation of cyclone Monica. The calibration coefficient was not changed during this period so the wind speeds are a little low (0.2%). |

Subject: | TWP/SMET/C3 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC3.b1 |
Description: | A tipping bucket rain gauge was added to the SMET suite of instruments effective 20060926. Two new variables (count and rain amount) were added at the end of the twpsmet60sC1.b1 datastream. When reprocessing of this datastream occurs these variables will be added with -9999 (missing) as the value for dates prior to gauge installation. |

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. |
