| Subject: | SGP/EBBR/E4 - Soil Temperature #5 Spiking Upwards |
| DataStreams: | sgp30ebbrE4.b1 |
| Description: | Soil temperature #5 experienced some erratic behavior during nighttime, spiking upwards slightly at times (mouse activity?). This caused soil moisture #5 to be corrected downwards very slightly. |

| Subject: | SGP/EBBR/E4 - Improved EBBR CR10 Program |
| DataStreams: | sgp30ebbrE4.b1 |
| Description: | Effective 20050323.1800, the EBBR.E4 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 20050323, 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 sgp30ebbrE4.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE4.a1). |

| Subject: | SGP/EBBR/E4 - Average Soil Heat Flux Incorrect |
| DataStreams: | sgp30ebbrE4.b1 |
| Description: | A typo in the version 9 EBBR program caused average soil heat flow to be zero, resulting in both sensible and latent heat fluxes being approximately 20 watts per meter squared too large during the middle of the day. |

| Subject: | SGP/EBBR/E4 - metadata corrections |
| DataStreams: | sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1 |
| Description: | On 20050817, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E4 data collected by ARM back to the installation of the instrument in April 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") |

| DataStreams: | sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1 |
| Description: | The top dome of the net radiometer was broken, resulting in net radiations that were too small, and thus sensible and latent heat fluxes that were too small. |
