DataStreams: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1 |
Description: | The right air temperature was going offscale at times. This problem seemed to end without Site Ops. intervention. |

Subject: | SGP/EBBR/E27 - Missing data during system update |
DataStreams: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1 |
Description: | Some soil parameters were slightly incorrect since EBBR.E27 was installed in May 2003. While the coefficients were being updated, data collection was suspended resulting in missing data for the specified period. No significant effects (1% or less) on the surface heat flux data would have occurred from using the slightly incorrect coefficients. Therefore, flagging of the surface flux data from the time of installation of E27 is unwarranted. |

DataStreams: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.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: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1 |
Description: | The right air temperature, and therefore top and bottom air temperatures were offscale or incorrect on occasion. Bowen ratio, sensible heat flux, and latent heat flux were also incorrect during those times. Inspection of the data is required to detect the incorrect periods. |

DataStreams: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1 |
Description: | Tair left dropped out at times. When this occurred, the sensible and latent heat fluxes are incorrect. Tightening of the electronic connections to the datalogging equipment appears to have solved the problem. |

DataStreams: | sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1 |
Description: | On 20050816, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E27 data collected by ARM back to the installation of the instrument in May 2003. 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 moisture units (from "by volume" to "gravimetric") |
