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: | During much of the indicated period the Left T/RH Temperature was incorrect. Because the home signal was between 0 and 3, the temperature was incorrect when the AEM was at the bottom position, but was correct when the AEM was at the top position. This was caused by a short created when the sensor was mispositioned in the aspirator housing and enough strain on the cable for it to bring it into contact with the housing in the bottom position. |

Subject: | SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect |
DataStreams: | sgp30ebbrE15.b1 |
Description: | The soil Moisture coefficients used for E15 were incorrect from the time of installation of the system in program version 8. On 9 July 02 parameter 4 (an offset value) of program step 136 was changed from 9.5264 to the correct value 0.95264 (this error had been made by the vendor). The error masked the real problem (wrong soil type) and after 9 July 02 resulted in very low soil moisture measurements. The coefficients used were for coarse sand. On 28 Sep 04 I visited the E15 site and found the soil type a fine sandy clay or fine sandy loam. I changed the coefficients at 1509 GMT to those for a very fine sandy loam; this produced reasonable soil moistures for the soil type. The old coefficients in parameters 4 through 9 for step 136 of the program were: 0.95264, -6.7859, 36.224, -58.619, 25.073, 4.2278 The new coefficients are: 10.241, -27.943, 49.523, -12.648, -52.643, 38.054 |

DataStreams: | sgp30ebbrE15.b1 |
Description: | Use of the wrong soil type soil moisture coefficients caused soil moisture to be greatly undermeasured (a typical wrong value was 4% instead of the correct 17%), soil heat flows to be undermeasured, and sensible and latent heat fluxes to be overestimated. Soil heat flow plate outputs were undermeasured by up to 10%, change of energy storage was undermeasured by up to 80% and total soil heat flow was undermeasured by up to 50% as a result. This would result in approximately a 5% overestimation of both sensible and latent heat fluxes. |

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). |

Description: | Effective 20050330.0000, the EBBR.E18 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 20050330, 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 sgp30ebbrE18.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE18.a1). |

Subject: | SGP/EBBR/E18 - Wind Direction Dependency of Surface Fluxes and General Data Quality |
DataStreams: | sgp30ebbrE18.b1 |
Description: | Beginning in FY2006, Data Quality Reports are not written for missing data or for situations when qc flags clearly show that the data is incorrect (this is true for most of the conditions listed below). DQRs are written for periods when data is incorrect, when the situation is not represented by qc flags in the data, and it's not obvious that the data should have been flagged as incorrect. The EBBR data is only useful for particular wind directions at each Extended Facility. Please use the following resources to help in interpreting the EBBR data. 1) qc flags in the EBBR data. 2) Instrument Mentor Monthly Summaries (IMMS) at http://www.db.arm.gov/IMMS/ 3) SGP EF Surface Conditions Observations (EFSCO) at http://198.124.96.210:591/sfc_cond1/default.htm 4) Surface fluxes are valid only for the following wind directions (in degrees): 138-325 Note that there are wind directions at most sites for which the fetch is insufficient and therefore EBBR data is invalid. Appropriate fetch was determined from a 1/40 measurement height to fetch ratio, resulting in a required minimum fetch of 120 m. Particular attention should be paid to the limited valid wind directions for the Central Facility EBBR. The surface vegetation type for the EBBRs is grazed or ungrazed grassland (refer to the EFSCO for state). 5) Some conditions that commonly cause the EBBR primary measurements to be incorrect or missing follow: a) Sensible and latent heat fluxes are not accurate during times when the Automatic Exchange Mechanism (AEM) is not functioning properly. The AEM switches the gradient measuring instrumentation between the top and bottom positions every 15 minutes; this reduces the effects of instrument offsets. Sometimes the AEM does not reach it's full extent of travel, resulting in the home signal being zero. b) Sensible and latent heat fluxes are sometimes incorrect when surface soil heat flow is out of range, as seen in the average soil heat flux (ave_shf). c) Very light winds may be seen at nights for brief periods. Wind direction flops around a lot during low wind conditions (< 1.5 m/s) and is often unreliable during those periods. d) Missing data periods occur at times; this is usually a site data system collection/communication problem; it can also occur during replacement of the system with a newly calibrated unit. Missing data is sometimes filled in later from manual or automatic re-collection of the data. |

DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1 |
Description: | The top net radiometer dome was broken, yielding net radiation, sensible heat flux and latent heat flux that were too low. The BEFLUX (SIRS) net radiation can be used as a replacement for the EBBR net radiation. To correct the sensible and latent heat fluxes, determine the ratio of SIRS net radiation to EBBR net radiation for each daylight half hour and multiply that ratio times H and LE to obtain approximate corrected flux values. |

Description: | Soil heat flow #4 was sometimes lower than the lower limit imposed in the EBBR programming; sensible and latent heat flux were therefore deemed to be suspect during those times.

DataStreams: | sgp15ebbrE18.b1, sgp30ebbrE18.b1 |
Description: | Soil heat flow #4 was replaced at the beginning of this period. However, the soil heat flow measurements from that sensor were sometimes still lower than the lower limit imposed in the EBBR programming; sensible and latent heat flux were therefore deemed to be suspect during those times. The cause of the low values could not be determined, but the values are not reasonable for the vegetation type at EF18. To remedy the situation, the soil heat flow sensor calibration was changed so that the sensor provided measurements that resembled the other four soil heat flow sensor measurements. Soil heat flow measurements have been reasonable since the calibration change. |
