Subject: | SGP/EBBR/E19 - AEM Hung Inbetween Home Positions |
DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | The AEM hung inbetween home positions, producing a home signal of zero. Sensible and latent heat fluxes during this period are incorrect. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | An ice storm froze the wind speed sensor to a stopped condition. 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: | The wind direction sensor was frozen stopped by ice from a storm. The wind direction, sigma_wd, and residual wind speed measurements are incorrect. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | Wind Speed was constant at 5 m/s during this period; the reason is unknown. This sensor failure does not affect the sensible and latent heat fluxes. |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | The net radiation measurement was incorrect after the net radiometer cable was chewed by rodents. Sensible and latent heat fluxes were therefore incorrect. |

Subject: | SGP/EBBR/E19 - metadata corrections |
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") |

DataStreams: | sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | The gradient measurements and latent and sensible heat fluxes were incorrect because the AEM was not exchanging. The problem was fixed by replacing the AEM. |
