Subject:	SGP/EBBR/E4 - T/RH Check
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.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: 1620, 1625, 1630, 1635, 1640, 1645, 1650, 1655, 1700, 1705, 1710, 1715, 1720, 1725, 1730, 1735, 1740 15 minute: 1630, 1645, 1700, 1715, 1730, 1745 30 minute: 1630, 1700, 1730, 1800 (EDITORS 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.

Description:	On September 11, 1993 soil heat flux sensor #4 of the Plevna, KS EBBR (E4) malfunctioned. The sensor was replaced September 23, 1993 before 1600. Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e, and corrupted 15 minute values of mv_hft4 resulted from the sensor malfunction. The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and are not recoverable. The other quantities can be recalculated using the three functioning sets of soil sensors. (Note: Soil heat flux sensor #5 was also malfunctioning during the time periods identified and has therefore been eliminated from the recalculation equations. This problem is identified in a separate DQR.) ave_shf = (g1 + g2 + g3)/3 e = -(q + ave_shf)/(1 + bowen) h = -(e + ave_shf + q)

Description:	On September 1, 1993 the EBBR system at Plevna, E4, was relocated in the same field. However, soil contact for soil heat flux plate #5 was not properly established. This resulted in somewhat high positive and very high negative outputs, depending on the direction of soil heat flow. Corrupted 30 minute values of shf4, c_shf4, g4, ave_shf, h, and e, and corrupted 15 minute values of mv_hft4 resulted. The quantities shf4, c_shf4, g4, and mv_hft4 are bad data values and are not recoverable. The other quantities can be recalculated using the four functioning sets of soil sensors. (Note: Soil heat flux sensor #4 was also malfunctioning during part of the time period identified. That problem is identified in two separate DQRs. See D931108.5 and D020701.2 for the equations to use while sensor #4 was not working properly) ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(e + ave_shf + q)

Description:	During two half hours, soil moisture probe #5 indicated values that were offscale for an unknown reasons. Affected data values are: 15 minute: rr_sm5 30 minute: sm1, c_shf5, cs5, ces5, g5, ave_shf, e, h Sensible, latent, and soil heat fluxes can be recalculated using the change in energy storage of probes 1-4 as follows. ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(e + ave_shf +q)

Subject:	SGP/EBBR/E4 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE4.b1
Description:	Effective 20050323.1800, the EBBR.E4 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 20050323, 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 sgp30ebbrE4.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE4.a1).

Subject:	SGP/EBBR/E4 - Average Soil Heat Flux Incorrect
DataStreams:	sgp30ebbrE4.b1
Description:	A typo in the version 9 EBBR program caused average soil heat flow to be zero, resulting in both sensible and latent heat fluxes being approximately 20 watts per meter squared too large during the middle of the day.

DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	On 20050817, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E4 data collected by ARM back to the installation of the instrument in April 1993. 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")
