Subject: | SGP/EBBR/E26 - Wind Speed Frozen Stopped By Ice Storm |
DataStreams: | sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.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: | sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.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. |

Subject: | SGP/EBBR/E26 - Aging Pressure Sensor Output Changes With Supply Voltage |
DataStreams: | sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1 |
Description: | The E26 EBBR pressure sensor experienced the poor internal voltage regulation problem experienced at other sites last year. Aging of the internal voltage regulator caused the pressure output to drop by 1-2 kPa (0.1-0.5 kPa is normal) when the Sun rose and the solar panel goosed the battery voltage up. The sensible and latent heat fluxes were not significantly affected. |

Subject: | SGP/EBBR/E26 - metadata corrections |
DataStreams: | sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1 |
Description: | On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E26 data collected by ARM back to the installation of the instrument in June 1992. 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") |

DataStreams: | sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1 |
Description: | Low battery supply voltage resulted in high home signals and questionable data at times. Data for battery voltage <10.5 volts should be considered to be incorrect. |
