DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.00, sgp5ebbrE13.b1 |
Description: | A lightning strike to the central cluster area shortly after 0800 GMT on July 17 caused failure of several EBBR sensors: both humidity probes, the barometer, soil heat flux #3, soil moisture # 1 and the wind direction. These failed sensors caused sensible, latent, and average soil heat flux to be incorrect until site operations performed maintenance on July 24th. Site Operations found a loose connection from soil moisture probe #1, removed barometer SN 6578 and replaced it with SN 6507, removed soil heat flux sensor #3 with SN 923022 and replaced it with SN 933199, repositioned the wind direction sensor - which was rotated approximately ninety degrees clockwise from its proper position, and removed the right humidity probe SN 460412 and replaced it with SN 460428. |

DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.00, sgp5ebbrE13.b1 |
Description: | A lightning strike to the central cluster area on 17 July 1995 caused failure of several EBBR sensors including the right humidity probe. On July 24th, site operations removed the right humidity probe SN 460412 and replaced it with SN 460428 In less than a day the right humidity probe output soared to over 113% and has hovered around 112% since. I consider all right probe values to be incorrect due to this behavior. Without a properly functioning right humidity probe, all values of top and bottom relative humidity, top and bottom vapor pressure, Bowen ratio, and latent and sensible heat fluxes are incorrect. A working spare relative humidity probe was not available at that time. The probe was replaced with a working, calibrated probe on 22 September 1995 at about 2108 GMT. I have the examined the data since the day of the replacement and find that the new probe is working well. All E13 EBBR measurements are presently correct. The old probe S/N was 460428, the new S/N is 460413. |

DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1 |
Description: | Soil Temperature #4 produced noisy measurements, resulting in quantities calculated from it to be of suspect quality. This condition normally occurred early in the GMT day. Sensible (h) and latent (e) heat fluxes were not normally greatly affected. Average surface heat flow was normally slightly underestimated. |

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. |

DataStreams: | sgp15ebbrE12.b1, sgp30ebbrE12.b1, sgp5ebbrE12.b1 |
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. |

Subject: | SGP/EBBR/E9 - T/RH Check |
DataStreams: | sgp15ebbrE9.b1, sgp30ebbrE9.b1, sgp5ebbrE9.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: 1820, 1825, 1830, 1835, 1840, 1845, 1850, 1855, 1900, 1905, 1910, 1915, 1920, 1925, 1930, 1935, 1940, 1945 15 minute: 1830, 1845, 1900, 1915, 1930, 1945 30 minute: 1830, 1900, 1930, 2000 (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. |

Subject: | SGP/EBBR/E13 - AEM Hung up |
DataStreams: | sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.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. |

The heat fluxes can be recalculated by using soil sets 1-4 as follows: ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) |

Description: | The Right Humidity measurement was normally incorrect, although it is often difficult to determine it by looking at the measurement. The measurements float around, sometimes being too large and sometimes being too small, through most of the day, particularly for the hour before sunset through the hour after sunrise. Great care and comparison with surrounding EBBR sites would be needed to be able to use any of the latent and sensible heat flux measurements from E9 for this period. Another DQPR has been issued to fix this problem, which has eluded repair efforts so far. |

Description: | The barometer output was scaling with supply voltage (i.e. it followed the charging of the battery by the solar panel). NOTE: The barometer was replaced later than the end date of this DQR. Why the problem ended on 26 Nov 2003 is unclear; there was no site ops intervention on that date. The problem did not affect the sensible and latent heat flux calculations beyond the expected system error. |

Description: | The AEM was stuck in the home_15 position or reported near zero home signals during much of the indicated period. The Bowen ratio and latent and sensible heat fluxes were incorrect when the AEM was not operating properly; the periods of incorrect data can be determined from the home signal values. On 7/14/04 the AEM was replaced. |

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). |

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 20050322, 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 sgp30ebbrE9.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE9.a1). |

DataStreams: | sgp30ebbrE12.b1 |
Description: | Effective 20050329.1830, the EBBR.E12 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 sgp30ebbrE12.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE12.a1). |

Subject: | SGP/EBBR/E13 - Radiometer dome broken |
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. |
