Subject: | SGP/EBBR/E19 - Water in Net Radiometer; Surface Fluxes are Incorrect |
DataStreams: | sgp15ebbrE19.a1, sgp15ebbrE19.b1, sgp30ebbrE19.a1, sgp30ebbrE19.b1, sgp5ebbrE19.a1 |
Description: | The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements. However, when it subsequently rains, water collects in the bottom dome, causing the net radiation measurements to be too large during the day and too small at night. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | Battery voltage dropped below levels required to sustain the production of valid data. The AC charger unit had failed. This prevented charging of the battery during the night and prevented the solar panel regulator from properly charging the battery during the day. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | The AEM home 15 and 30 outputs were both 40 mv because the AEM was not exchanging. Sensible and Latent Heat Fluxes are therefore incorrect. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | An ice storm froze the wind speed sensor to a stopped condition. It is not known how long this condition existed, as data is missing for more than 10 days after the end of the stated period. The wind speed and residual wind speed measurements are incorrect. This sensor failure does not affect the sensible and latent heat fluxes. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E19 data collected by ARM back to the beginning of the data set in May 1997. Please see the current metadata for correct information. These changes do not affect data values or quality. The changes are summarized below: 1) Update of "sensor location" information 2) Addition of installation dates for the systems 3) Correction of soil type 4) Correction of soil moisture units (from "by volume" to "gravimetric") |
