Subject: | SGP/EBBR/E25 - Reprocess: Soil Heat Flow #5 Negative Offset |
DataStreams: | sgp30ebbrE25.a1, sgp30ebbrE25.b1 |
Description: | Soil heat flow 5 was either too large negative or negative when it should have been positive; the cause of the negative offset is unknown, but is often the result of a failed J-panel over-voltage protection device. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) |

Description: | Change of energy storage (CES) measurements (calculated from the change of soil temperature with time) are sometimes incorrect after a CR10 program restart because the beginning measurement of the averaging period is zero. Average soil heat flow, sensible heat flux, and latent heat flux were affected and cannot be recalculated. |

DataStreams: | sgp15ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.a1, sgp30ebbrE26.b1, sgp5ebbrE26.a1 |
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 - AEM Home Signals Too High |
DataStreams: | sgp30ebbrE22.a1, sgp30ebbrE22.b1, sgp5ebbrE22.a1 |
Description: | The AEM home signals were too large at times during the indicated period; it has been determined by the vendor that this is usually caused by electrical noise in the vicinity. When the 30 minute data shows a home 30 signal of 35 or more, the bowen ratio, and sensible and latent heat flux measurements are incorrect Removing the jumper between 4L and AG on the CR10 and adding a jumper to Multiplexer 2, Set 6, between L1 and L2 fixed the problem. The vendor intends to make this modification to all EBBR systems as they return for re-calibration. |

DataStreams: | sgp30ebbrE26.a1, sgp30ebbrE26.b1 |
Description: | The half hour after restart of the CR10 datalogger, the soil temperatures for the beginning of the period are missing. Therefore the soil energy storage and surface flux values are also incorrect. |

Description: | The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements. However, when it subsequently rains, water collects in the bottom dome, causing the net radiation measurements to be too large during the day and too small at night. |
