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. |

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/C1 - Reprocess: Tipping bucket rain gauge added |
DataStreams: | twpsmet60sC1.b1 |
Description: | A tipping bucket rain gauge was added to the TWP.C1 SMET suite of instruments on 20061017. Effective 20060926, two new variables (count and rain amount) were added to the end of the twpsmet60sC1.b1 datastream. Between 9/26 and 10/17, the data for these two variables are filled with zeros. Users should not use the data during this period as the zeros are not representative of the rain fall at the site. When reprocessing of this datastream occurs these variables will be added for the 19961009-20060926 and data from 19961009-20061017 will be filled with -9999 (missing). |
