Subject: | SGP/EBBR/E7 - 6 Month Checks |
DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1 |
Description: | Many measurements were incorrect while the AEM was positioned with both aspirators at the same height for comparison checks. |

Subject: | SGP/EBBR/E7 - Pressure Sensor Data Incorrect |
DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.a1 |
Description: | The E7 pressure sensor suffered from spikes in pressure, which were related to increases in voltage during the day as the solar panels charged the battery. These spikes were not of a magnitude that would affect the 30 minute surface fluxes. Replacement of the pressure sensor solved the problem. |

DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1 |
Description: | The wind speed sensor was frozen stopped by ice. The wind speed and residual wind speed measurements are incorrect. |

Subject: | SGP/EBBR/E7 - Improved EBBR CR10 Program |
DataStreams: | sgp30ebbrE7.b1 |
Description: | Effective 20050322.1900, the EBBR.E7 CR10 program was revised to improve the quality of the primary measurements as follows: 1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow. This is applied to the individual soil sets. Measurements outside the limits are rejected and the measurements within the limits are used to calculate the average soil heat flow. 2) Max and min limits are used to determine incorrect values of net radiation, sensible heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal. If AEM signal is outside the limits, h and e are set to 999s. If net radiation is outside the limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s. Virtually no incorrect soil measurement will affect the primary measurements of h and e. By setting h and e to 999s, it can be easily seen that the primary variables are incorrect; no other interpretation is possible. Prior to 20050322, the improved CR10 program was NOT in effect. DQRs have been submitted for known instances of incorrect soil measurements which affected the quality of the primary measurements of h and e. Note: the DQR begin date is the begin date of the sgp30ebbrE7.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE7.a1). |

Subject: | SGP/EBBR/E7 - metadata corrections |
DataStreams: | sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1 |
Description: | On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E7 data collected by ARM back to the installation of the instrument in May 1993. 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") |
