Description: | This condition occurred most of the time during the indicated period (hence color yellow). The left air temperature was incorrect only when the AEM was in the home 30 position. This only affected the bottom air temperature calculation. However, it made the latent heat flux, sensible heat flux, and Bowen ratio incorrect. The sensor was improperly inserted into the aspirator shield and was pinched between the shield and the T/RH probe. When the AEM was in the home30 position, the aspirator hose position may have caused the sensor to short to ground. |

Description: | Soil Temperature #4 was often incorrect, typically too large negative, during this period, causing other measurements calculated with it to be incorrect also. This was caused by a bad multiplexor channel, which was discovered by the vendor during recalibration of the unit later. |

DataStreams: | sgpthwapsC1.a1, sgpthwapsC1.b1 |
Description: | Power outages apparently led to the THWAPS HMP233 temperature and RH sensor being replaced at C1. The power went out at 0340 on 3/9 was restored at 0635 and went out again at 2025. The new HMP233 appears to be incorrectly calibrated and all temperature data since its installation are wrong. If I am correct about the nature of the calibration problem, the true average temperature can be recovered from that recorded by a linear conversion, but I don't think its worth the trouble. |

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: | sgp30ebbrE13.b1 |
Description: | Effective 20050331.2100, the EBBR.E13 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 20050331, 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 sgp30ebbrE13.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE13.a1). |

Subject: | SGP/ECOR/E14 - Flux Measurements Incorrect |
DataStreams: | sgp30ecorE14.b1 |
Description: | The ECOR datastream was corrupted; this happens when the ECOR program produces a datastream of the wrong length (i.e., leaves one or measurements out). Fluxes and some other measurements are incorrect. Note: Mentor reports reprocessing will not correct this problem. |

Subject: | SGP/EBBR/E13 - Soil Heat Flow #3 Large Negative |
DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | During this period Soil Heat Flow #3 was sometimes incorrect (large negative); during those times, sensible and latent heat fluxes and average soil heat flux were sometimes (but not always incorrect). |

DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | During spikes in pressure upwards or downwards the sensible and latent heat fluxes were incorrect. |

Subject: | SGP/EBBR/E13 - Most Measurements Incorrect When Battery Voltage Too low |
DataStreams: | sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | Most measurements were incorrect during this period because the battery voltage was below 10.5 volts. |
