Subject:	SGP/EBBR - EBBR E7 Soil Moisture Sensors #2 and #4 Negative
DataStreams:	sgp15ebbrE7.a1, sgp30ebbrE7.a1
Description:	Soil moisture sensors #2 and #4 produced negative values for soil moisture frequently during the period, causing the quantities calculated from them to be incorrect. The version of the CR10X program at E7 does not have max/min limits on the outputs. The data needs to be examined to determine times of incorrect soil moisture values. The data values affected are shown below. 15 minute: r_sm1, r_sm2, r_sm3, r_sm4, r_sm5 30 minute: sm1, sm2, sm3, sm4, sm5, c_shf1, c_shf2, c_shf3, c_shf4, c_shf5, g1, g2, g3, g4, g5, ave_shf, e, h

Subject:	SGP/EBBR - EBBR E7 Soil Moisture Sensor #5 Negative
DataStreams:	sgp15ebbrE7.a1, sgp30ebbrE7.a1
Description:	Soil moisture sensor #5 produced small negative values for soil moisture infrequently during the period. Because the vales were small negative, no calculated data values are adversely affected. The data needs to be examined to determine times of incorrect soil moisture values. The data values affected are shown below. 15 minute: r_sm5 30 minute: sm5
Measurements:	sgp30ebbrE7.a1: volumetric soil moisture, site 5(sm5) sgp15ebbrE7.a1: Soil moisture 5(r_sm5)

Subject:	SGP/EBBR/E7 - Reprocess: Soil Temperature Probe Failure
DataStreams:	sgp15ebbrE7.a1, sgp30ebbrE7.a1
Description:	Failure of soil temperature probe #4 at E7, Elk Falls, KS resulted in incorrect data values for 6 fields for the period of time listed above. The soil temperature value from probe #4 went offscale, resulting in a zero value for the soil energy storage term calculated from that probe and thus no contribution to the total soil heat flux for soils set 4 and the same for average soil heat flux. This led to incorrect sensible and latent heat flux values. The fields affected were: 30 minute: ts4, ces4, g4, ave_shf, e, h 15 minute: rr_ts4.
Measurements:	sgp15ebbrE7.a1: Soil temperature 4(rr_ts4) sgp30ebbrE7.a1: latent heat flux(e) 0-5 cm change in soil heat storage with time, site 4(ces4) 0-5 cm integrated soil temperature, site 4(ts4) soil heat flow, site 4(g4) average surface soil heat flow(ave_shf) h(h)

Description:	DQR No: Platform: EBBR Subject: Stopped Ventilation Fan Date Submitted: 30 August 1994 Submitted By: _x_ Instrument Mentor ___ EST Member ___ Science Team Member ___ Other _____________________________ For questions or problems, please contact the ARM Experiment Center at 509-375-6898 or via email at dqr@arm.gov. Platform/Measurement: What level data: (raw,a0,a1,b1,c1 etc): a0 (5 minute), a1 (15 and 30 minute) What location was the data collected at: E7, Elk Falls, KS Period of time in question Begin Date 8/9/94 End Date 8/23/94 Time 1922 GMT Data should be labeled: ___ questionable ___ All data fields affected ___ incorrect _x_ Only some data fields affected ___ wrong calibration _x_ others (information only) Discussion of Problem: Sometime between August 9 and 23, 1994 the ventilation fan of the EBBR stopped; the fan guard was clogged with insect remains. The fan was restarted at 1922 GMT on 23 August. Inspection of the EBBR data does not indicate any ill affects on the calculated sensible and latent heat during the period. The fan may have stopped soon before the arrival of the site operator on 23 August. I cannot suggest flagging the data as incorrect, but this message should still be attached to the data so that anyone who might discover something unusual may have some basis for explaining it.

Only a few weeks earlier the same situation occurred at this EBBR. The 15 minute data reveals that most of the time the right aspirator fan was the one that failed to work, although there are times that it appears that the left fan was either not working also or was the only one not working. Unlike the previous occurrence, the 30 minute flux data does show some indication of this problem, although, as usual, it is far easier to see in the 15 minute data. The fans were cleaned out and restarted at 1530 GMT on September 21, 1994.

Subject:	SGP/EBBR/E7 - Net Radiometer not level
DataStreams:	sgp15ebbrE7.a1, sgp30ebbrE7.a1, sgp5ebbrE7.a0
Description:	Sometime between 0000 and 1200 GMT on October 20, 1994, the net radiometer support of the EBBR at E7 was bent down at about a 30 degree angle, probably by migrating birds. A couple of DQRs have been issued by me indicating other extended facilities at which birds have caused incorrect data from net radiometers. The net radiometer support was probably loose to begin with. The effect can be easily seen in the data, when comparison is made to the EBBR data at Ashton, KS. Since the net radiometer support extends south from the EBBR, the net radiation values are high during the period above, leading to incorrect values of latent and sensible heat fluxes. Until the net radiometer was levelled on November 1, 1994, the net radiation was approximately 26% high at solar noon, although it may have been incorrect by a smaller percentage at night. From October 22 through 28 the half hour of data nearest solar noon averaged 497 watts per meter squared at Elk Falls and only 396 at Ashton. During the period listed above, the following data are incorrect and cannot be recalculated: 5 minute: q 15 minute: mv_q 30 minute: q, h, e Science Team members or others using the data should recognize that the flux data is not correct for this fairly lengthy time period.

Subject:	SGP/EBBR/E7 - Radiation Shield Problem
DataStreams:	sgp30ebbrE7.a1, sgp5ebbrE7.a0
Description:	The right radiation shield was out of position or off during the period of time indicated. This may or may not have occurred as a result of preventative maintenance on November 15. All air and humidity probe temperatures (except the reference temperature), relative humidities, vapor pressures, Bowen ratio, sensible heat flux, and latent heat flux during this period are questionable. During a large part of the period the resultant sensible and latent heat fluxes look reasonable. However, during part of the period, the difference in relative humidity between the two EBBR levels appears to be much too large. Unusual differences in temperatures are not as obvious.

Description:	A small amount of water collected in the bottom dome of the net radiometer. It is not obvious that it had been there for more than several hours before the site operators arrived for a preventative maintenance visit and there is no evidence of any effects on the data (there had been heavy cloudiness for the previous several hours). The only incorrect data occurred during the removal of the water. The dome was not replaced.

Subject:	SGP/EBBR/E26 - T/RH Check
DataStreams:	sgp15ebbrE26.a1, sgp30ebbrE26.a1, sgp5ebbrE26.a0
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: 1615, 1620, 1625, 1630, 1635, 1640, 1645, 1650, 1655, 1700, 1705, 1710, 1715, 1720, 1725, 1730, 1735 15 minute: 1615, 1630, 1645, 1700, 1715, 1730, 1745 30 minute: 1630, 1700, 1730, 1800 (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.

DataStreams:	sgp15ebbrE9.a1, sgp30ebbrE9.a1, sgp5ebbrE9.a0
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.

Platform/Measurement: EBBR/Changeout What level data: (raw,a0,a1,b1,c1 etc): a1 (5 and 30 minute) a0 (15 minute) What location was the data collected at: E7, Elk Falls, KS Period of time in question Begin Date 11/02/95 Time 1530 GMT End Date 11/28/95 Time 2200 GMT Data should be labeled: ___ questionable ___ All data fields affected part of the period) _X_ incorrect _X_ Only some data fields affected ___ wrong calibration ___ others Discussion of Problem: On November 2, 1995 the changeout for annual calibration occurred at E7, Elk Falls, KS. SEBS unit 9 was removed and unit 12 was installed. Between 1530 and 1930 GMT no data was collected. The soil moisture probes were shipped dry from the vendor. Site operations did not realize this and installed them without wetting the bags that hold the soil moisture probes in soil. The water did not penetrate into the bags of soil. Therefore, some soil moisture probe outputs were initially offscale. Different soil moisture probes indicated offscale at different times until 28 November 1995. On 28 November, site operations soaked the soil moisture probe bags with water, causing the soil moisture data values to come on scale. No data was collected during the time of the installation on November 2, between 1530 and 1930 GMT. The incorrect soil moisture after SEBS 12 was installed affected numerous data values including: 15 minute: rr_sm1, rr_sm2, rr_sm3, rr_sm4, rr_sm5 30 minute: h, e, ave_shf, shf1, shf2, shf3, shf4, shf5, sm1, sm2, sm3, sm4, sm5, cs1, cs2, cs3, cs4, cs5, ces1, ces2, ces3, ces4, g1, g2, g3, g4, g5. Inspection of the data readily shows which soil moisture probes were offscale. When one or more were offscale, the e, h, and ave_shf data and the respective numbered data variables above were incorrect. h and e can be recalculated using only correct soil moisture probe values and equations shown in many previous DQRs.

Description:	DQR No: Platform: EBBR Subject: E7 Soil Moisture Probes Offscale Date Submitted: January 19, 1996 Submitted By: _x_ Instrument Mentor ___ EST Member ___ Science Team Member ___ Other _____________________________ For questions or problems, please contact the ARM Experiment Center at 509-375-6898 or via email at dqr@arm.gov. Platform/Measurement: EBBR/Soil Moisture Probes What level data: (raw,a0,a1,b1,c1 etc): a1 (15 and 30 minute) What location was the data collected at: E7, Elk Falls, KS Period of time in question (Times vary for different days) Date 01/07/96 Time 0530-2400 GMT Probe sm2 0530-2130 GMT sm4 1100-1900 GMT sm5 01/08/96 0000-2400 GMT sm2 0130-2300 GMT sm4 0130-2030 GMT sm5 01/09/96 0000-2200 GMT sm2 1130-1900 GMT sm4 1130-1730 GMT sm5 Data should be labeled: ___ questionable ___ All data fields affected _X_ incorrect _X_ Only some data fields affected ___ wrong calibration ___ others Discussion of Problem: During numerous periods within the days listed above, individual soil moisture probes indicated high or offscale, on the dry side. The cause of the problems is unknown. Data since 9 January 1996 has been correct. Recalculation of ave_shf, e, and h must be made using only the soil moisture sets with correct soil moisture values. Affected data values are (# for probe number): 15 minute: rr_sm# 30 minute: sm#, c_shf#, cs#, ces#, g#, ave_shf, e, h Sensible, latent, and soil heat fluxes can be recalculated using the soil probe sets that provide correct data. For example, if soil moisture 2 is incorrect, ave_shf = (g1 + g3 + g4 + g5)/4 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), If soil moisture 2 and 4 are incorrect, ave_shf = (g1 + g3 + g5)/3 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), If soil moisture 2, 4, and 5 are incorrect, ave_shf = (g1 + g3)/2 e = -(q + ave_shf)/(1 +bowen) h = -(e + ave_shf +q), Other observations/measurements impacted by this problem: see above Suggested Corrections of the Problem: (e.g. change calibration factor and recompute, flag data with this comment, etc.) Flag data with this comment.

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.
