DataStreams: | sgp15ebbrE9.a1, sgp15ebbrE9.b1, sgp30ebbrE9.a1, sgp30ebbrE9.b1 |
Description: | Soil moisture probe #5 in the recalibrated unit installed on 5/11/01 has not been working all of the time. At times the measurement has been very large and incorrect. The indicated measurements are incorrect at those times. The data must be inspected to determine the times that have incorrect data. The sensible and latent heat fluxes can be recalculated by using soil sets 1, 2, 3, and 4 only in a recalculation of the energy budget. |

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. |

Subject: | SGP/EBBR/E9 - Improved EBBR CR10 Program |
DataStreams: | sgp30ebbrE9.b1 |
Description: | Effective 20050322.1600, the EBBR.E9 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 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). |

Description: | On 20050420, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E9 data collected by ARM back to the installation of the instrument in December 1992. Please see the current metadata for correct information. These changes do not affect data values or quality. The changes are summarized below: 1) Update of "sensor location" information 2) Addition of installation dates for the systems 3) Correction of soil moisture units (from "by volume" to "gravimetric") |

Subject: | SGP/EBBR/E9 - Temperature Portion of T/RH Probe |
DataStreams: | sgp15ebbrE9.a1, sgp30ebbrE9.a1 |
Description: | The Temperature portion of the right T/RH probe indicated too high a temperature for nearly 11 months. I twice placed work requests to have the probe replaced, but no spares were available. Spares recently became available and I placed a new work request to have the probe changed. The replacement occurred on 18 June 1997; this fixed the problem. The main results of the high temperatures were probe top and bottom temperatures (used only for the calculation of vapor pressure) and vapor pressures that were too large. Furthermore, this caused latent heat flux to be reported to be too large, and therefore sensible heat flux was reported to be too small. Recalculation of the fluxes using thermocouple temperatures to calculate vapor pressure would be quite time consuming and would have to assume that the thermocouple temperature and probe temperature were nearly the same. The EBBR procedures have been changed to include comparison of the thermocouple and probe temperatures to make it easier for the site operators to detect this condition. The data affected (and thus incorrect) includes: 15 minute: rr_thum_r 30 minute: thum_top, thum_bot, vp_top, vp_bot, e, h, bowen. |

Description: | During EBBR 6 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 these periods 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 correct gradients. Checks performed before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for periods indicated. |

DataStreams: | sgp15ebbrE9.a1, sgp30ebbrE9.a1, sgp5ebbrE9.a0 |
Description: | The upper dome of the EBBR net radiometers was punctured. After the puncture, water collected in the top and/or bottom dome. The water was removed and the dome was replaced during PM visits. In some cases, the puncture and water resulted in incorrect data. Comparison with net radiation values from surrounding EBBR sites and the SIRS is neccesary to determine if the EBBR net radiation data are correct or incorrect. It is often difficult to tell from the data when the punctures occurred, but they would have existed for no more than 2 weeks, since the domes are checked during each two-weekly PM visit. Incorrect net radiation data results in the latent heat flux and sensible heat flux also being incorrect. |
