Description: | The AEM kept stopping in one of three positions, none of which allow sensible heat flux, latent heat flux, or Bown ratio to be calculated correctly. These and the gradient measurements are incorrect for the period indicated. The AEM stopped in either the home15 position (home signal about 53), the home 30 position (home signal about 23), or inbetween these two (home signal 1 to 2). |

DataStreams: | sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1 |
Description: | Soil Temperature #2 was intermittently incorrect. The cause is unknown. The indicated measurements that are calculated using soil temperature are also incorrect. Soil moisture #2 (30 minute only) was also affected because version 6 of the EBBR datalogger program uses a multiplication of soil temperature and soil moisture as part of the adjustment of soil moisture for soil temperature. This was discovered to be a poor technique soon after it was implemented, but E2 will continue to use version 6 until a replacement EBBR unit is available. When soil temperature #2 is large negative, soil moisture #2 is often twice as large as it should be. EBBR unit changeout dates are listed on the EBBR instrument web page. |

DataStreams: | sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1 |
Description: | Soil Temperature #2 was intermittently incorrect. The cause is unknown. The indicated measurements that are calculated using soil temperature are also incorrect. Soil moisture #2 (30 minute only) was also affected because version 6 of the EBBR datalogger program uses a multiplication of soil temperature and soil moisture as part of the adjustment of soil moisture for soil temperature. This was discovered to be a poor technique soon after it was implemented, but E2 will continue to use version 6 until a replacement EBBR unit is available. When soil temperature #2 is large negative, soil moisture #2 is often twice as large as it should be. EBBR unit changeout dates are listed on the EBBR instrument web page. |

Subject: | SGP/EBBR/E2 - Improved EBBR CR10 Program |
DataStreams: | sgp30ebbrE2.b1 |
Description: | Effective 20050324.1700, the EBBR.E2 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 20050324, 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 sgp30ebbrE2.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE2.a1). |

Subject: | SGP/EBBR/E2 - Net Radiation Incorrect; Latent and Sensible Heat Fluxes Incorrect |
DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1 |
Description: | The top dome of the net radiometer was broken and water entered, causing incorrect net radiation measurements. This resulted in incorrect sensible and latent heat fluxes. |

Subject: | SGP/EBBR/E2 - Average Soil Heat Flux Incorrect |
DataStreams: | sgp30ebbrE2.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/E2 - metadata corrections |
DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1 |
Description: | On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E2 data collected by ARM back to the installation of the instrument 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 moisture units (from "by volume" to "gravimetric") |

Subject: | SGP/EBBR/E2 - Sensible and Latent Heat Fluxes Incorrect |
DataStreams: | sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1 |
Description: | The sensible and latent heat fluxes and the gradient measurements were incorrect during this period because the AEM did not switch positions properly. |
