Description: | something, since the problem began during J-panel changeout the 4/7/99 PM. At the 7/21/99 PM, the reference temperature was repaired and reseated. At that time the SHF #5 data became correct again; the two events are probably related only in that other connections, including that of the SHF #5, were probably reseated at the same time. The report of the PM activity is not detailed enough to determine the exact causes and fixes. The incorrect SHF #5 data can be identified by it being an order of magnitude larger than the values from the other soil heat flow sensors. Affected data are: 5 minute: none 15 minute: mv_hft5 30 minute: shf5, c_shf5, g5, ave_shf, e, h |

DataStreams: | sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1 |
Description: | During the month of November 1994, site operations personnel conducted field comparisons of the temperature and relative humidity sensors in the EBBRs and the HMI31 portable T/RH meter (with the removable probe). As is reflected in the home signal output, the automatic exchange mechanism was disabled in order to conduct the checks. Measurements were taken every 5 minutes, for a half hour each in the aspirated radiation shields (the HMI31 was inserted into the EBBR aspirated radiation shield to provide the same aspiration as the EBBR sensors received). Measurements of aspirator flow were also recorded. This information was provided to the mentor. The mentor then compared the field checks with the data recorded by the EBBRs. The periods of data and data fields that are incorrect because of the checks are listed below. Times are those at which the data are reported. Data Fields 5 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot 15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l 30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot, bowen, e, h 5 minute: 1650, 1655, 1700, 1705, 1710, 1715, 1720, 1725, 1730, 1735, 1740, 1745, 1750, 1755, 1800, 1805 15 minute: 1700, 1715, 1730, 1745, 1800, 1815 30 minute: 1700, 1730, 1800, 1830 (EDITOR'S NOTE: The following analysis refers to all EBBRs installed in Nov 1994) Results of the T/RH comparisons: The combined accuracy of the HMI31 and EBBR temperature sensors (thermocouples or PRTDs) is +/- 0.4 degrees C. The combined accuracy of the HMI31 and EBBR RH sensors is +/- 4% for RH less than 80%, and +/- 6% for RH greater than 80%. The combined accuracy for each pair of EBBR sensors of the same type is essentially the same as the quantities stated above. All of the pairs of EBBR sensors show differences that fall within the stated combined accuracies. Although this sounds wonderful, a few of the differences are close to the combined accuracy, which, because of the small differences in temperature being measured (normally smaller than the magnitude of the combined accuracy) could lead to some incorrect estimation of sensible and latent heat flux. However, unless there would be substantial differences of calibration slope of two sensors in a pair, the switching of height of the sensors every 15 minutes by the automatic exchange mechanism will remove the offset between the sensors. The comparisons between the EBBR sensors and the HMI31 T/RH meter showed much larger differences. The range of differences were: -2.4 to 0.0 degrees for the thermocouples, -2.1 to 0.1 degrees for the RH probe PRTDs, and -6.6 to 6.7 percent for the RH sensors. Six Thermocouples indicated differences from the HMI31 greater than the combined accuracy. Seven PRTDs indicated differences from the HMI31 greater than the combined accuracy. Four RH sensors indicated differences from the HMI31 greater than the combined accuracy. The temperature differences (for both thermocouples and PRTDs) were nearly all of one sign; the HMI31 indicated the greater temperature, which may suggest a bias in the HMI31 temperature measurement, even though a dozen differences of +/- 0.2 degrees were measured. Four differences of zero and only one positive difference (out of 40) were measured. Thirteen of the 20 RH differences were positive (HMI31 indicating the lower RH), with the differences near the level of the combined accuracies being approximately 50% positive and 50% negative. It does not appear that the HMI31 has a RH bias. Plots of EBBR sensor/HMI31 differences as a function of time from the installation of the individual sensors (a range of 10 to 30 months in the field) shows no obvious pattern of sensor drift with time. This is encouraging. |

Description: | During EBBR 3 month checks the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during this period, at least, do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate gradients. Checks performed before or after the AEM is disabled also lead to some incorrect data. |

A DQPR has been submitted to replace #2. The indicated measurements that are calculated using soil temperature are also suspect. However, the intermittent problems normally occurred during night times and were fairly small in magnitude, thereby having little effect on the sensible and latent heat fluxes. |

DataStreams: | sgp30baebbrE19.c1, sgp30ebbrE19.b1, sgp5ebbrE19.b1 |
Description: | The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage calibration) was incorrect. Negative net radiations during the subject period can be multiplied by 0.9419 to get corrected net radiation measurements. The sensible (H) and latent heat (LE) fluxes (which are very small at night anyway) can be recalculated using the following equations (where B is Bowen ratio, Rn is corrected net radiation, and G is soil heat flow): LE = -(Rn + G)/(B + 1) H = -(Rn + G + LE) |

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: | sgp30ebbrE15.b1 |
Description: | Effective 20050329.1900, the EBBR.E15 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 20050329, 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 sgp30ebbrE15.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE15.a1). |

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 sgp30ebbrE19.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE19.a1). |

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. |
