DataStreams: | sgp5ebbrE2.b1, sgp15ebbrE2.b1, sgp30ebbrE2.b1 |
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). |

Subject: | SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect |
DataStreams: | sgp15ebbrE2.b1, 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. |

Description: | Soil Heat Flow probes #1 and #2 were incorrect during the indicated period (and for some time afterward, to be covered in another DQR). Outputs from the probes were typically too large negative or too large positive. |

DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | The AEM home30 signal is offset by approximately 25; it appears that the electronics of the AEM is adding the home15 and home30 voltages together when the AEM is in the home30 position. All gradient data, sensible heat flux, latent heat flux, and the Bowen ratio are incorrect during this condition. |

Description: | All sensors that depend on resistance measurements are incorrect. Average soil heat flow, sensible heat flux, and latent heat flux are incorrect as a result. This condition normally occurs when the reference temperature sensor is disconnected or bad. |

DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | The automatic exchange mechanism hung numerous times, but with various different measurements of home signals. In all cases, temperature and humidity gradients were incorrect; thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the indicated periods. Even when the home 15 and 30 signals were different (but too high) the measurements were incorrect because the program keys off of the home signals, which must be in the proper ranges. |

DataStreams: | sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.b1 |
Description: | Multiplexer 2 is failing during times of control box temperatures above 29 degrees C. The failure begins in the last channel and progresses to lower channels as the temperature increases. It has not yet been determined whether the failure is in the relays or a solid state component of the multiplexer. This condition is probably due to the aging of the device and the millions of cycles that this 10 year old device has made. More failures of this sort may occur in the future. A cure is being sought aside from replacement of the multiplexers to prevent the problem. The indicated measurements need to be inspected to determine which ones are usable. |

Description: | One of the multiplexers exhibited dropouts of the channels, beginning with the last channel at temperatures above about 30 C and moving backward through the channels as the temperature rose. High temperatures affected the switching speed of the multiplexer. This is the first time that this behavior has been documented in a Campbell Scientific multiplexer. The multiplexer had been in continuous field use for 10 years and had experienced probably more switching cycles than what is normally expected of the device in that period. The multiplexer was replaced to solve the problem. |

Subject: | SGP/EBBR/E22 - home30 too large |
DataStreams: | sgp5ebbrE22.b1, sgp15ebbrE22.b1, sgp30ebbrE22.b1 |
Description: | The home30 measurements sometimes exceeded 34.9999, resulting in the qc flag being set. However, this does not create any data quality issues. The qc flag is set just to provide an alert that the automatic exchange mechanism may have a problem; in this case data was not affected. An electronics repair solved the problem. |

DataStreams: | sgp5ebbrE15.b1, sgp15ebbrE15.b1, sgp30ebbrE15.b1 |
Description: | The wind direction at E15 EBBR was 10 degrees low for the period (since installation of the EBBR unit on 10/11/01). The wind direction sensor was apparently aligned to magnetic north instead of true north at installation. |

DataStreams: | sgp15ebbrE25.b1, sgp30ebbrE25.b1 |
Description: | During the entire span of EBBR.E25 data, the cdf data files contained a few minor global metadata errors. These errors do not affect the data values or quality. The errors include: * incomplete sensor location information * incomplete installation date information * soil moisture documented as "by volume" should have read "gravimetric" |
