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.

DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.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/E4 - AEM malfunction
DataStreams:	sgp30ebbrE4.b1, sgp5ebbrE4.b1, sgp15ebbrE4.b1
Description:	Beginning when the E4, Plevna EBBR was moved to a different location in the same area on August 29, 1993, the home_15 signal began to malfunction intermittently. The home_15 signal is normally between 45 and 53; in the case where it malfunctions, it reads approximately 22. The home signal is sampled only once per fifteen minute period to indicate the position of the Automatic Exchange Mechanism (AEM). However, the realtime value is used every 30 seconds to determine the sign of the gradient of temperature and relative humidity. Clearly, the 15 minute sample may not always reflect the proper position if something is wrong with the AEM. Therefore, when the home_15 signal is incorrect for a half hour, it is wise to view the preceding and successive half hours of data with suspicion as well as the half hour of interest. Affected data are 5 minute values of mv_home; 15 values of tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot, and home; 30 minute values of tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot, vp_top, vp_bot, bowen, e, h, and home_15. The dates on which this problem occurred were (all 1993) August 29, September 2, 3, 6-8, 10-16, 18-29, October 1-11, 13-31, and November 1-4. On November 4, 1993 the AEM was replaced at Plevna, correcting the problem described in this PIF.

DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	When a replacement net radiometer was installed on March 10, 1994, the calibration sheet for the new sensor could not be found. That was because the manufacturer had not provided one with the instrument. So, the calibration for the previous sensor was left in the EBBR CR10 program. I obtained the calibration sheet from the manufacturer, and upon return to Plevna on the next preventative maintenance visit, on March 24, site operations personnel entered the correct calibration into the program. The change in calibration was from 13.1 to 13.0. This change has negligible ( less than one percent) effects on calculations in the program and does not warrant recalculations. However, the net radiation itself could be recalculated by multiplying by the ratio of 13.0 to 13.1.

Description:	Soil heat flux plate #5 has indicated high at extremes, for both positive and negative outputs. At around -130 watts per meter squared for #5, the other four heat flux plates indicated approximately half as much. After replacement on June 2, 1994 at 1752 GMT, SHF #5 is now very similar to the other four plates. The effect on average soil heat flux amounted to only about 2% of the net radiation value at the worst; this is within the accuracy of the net radiation measurement and therefore does not require recalculation of the sensible and latent heat fluxes.

Subject:	SGP/EBBR/E4 - Pressure
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	Damage to some pressure sensors as a result, apparently, of high battery voltage, caused pressure readings to vary significantly at a few EBBRs for several months. I am being intentionally vague in making that statement as there are DQRs and at least one PIF that cover those cases, except for the situation at E4, Plevna, KS. Some time ago I had the suspect pressure sensors replaced and "repaired". Unfortunately, the repairs were insufficient, as we found out by using Plevna as a guinea pig for the "repaired" sensors to see if they were working. It turns out that the three repaired sensors S/N 6500, 6504, and 6509 were better, but still experienced fluctuations in output that followed battery voltage level as the battery was charged by the solar panel during the daylight hours. The fluctuations look like long-term spikes, positive or negative at different times, and lasted from one to several hours. The fluctuations had minimal impact on adjustments to computed values from the EBBR. Pressure data from Plevna for the period listed above should not be used for absolute values. That is why I marked "questionable", in the data labelling section, but this applies only to the pressure data itself. The following documents the use of pressure sensors at Plevna: 1) The original sensor, S/N 6509 was removed for repair on 1/13/94 and replaced with the "repaired" S/N 6500. 2) S/N 6500 was removed for repair on 2/10/94 and replaced with the "repaired" S/N 6504. 3) S/N 6504 was removed on 3/24/94 and replaced with "repaired" (2nd time) S/N 6500. 4) S/N 6500 was removed on 5/5/94 and replaced with "repaired" (2nd time) S/N 6504. 5) S/N 6504 was removed on 5/19/94 and replaced with "repaired" S/N 6509. 6) S/N 6509 was removed on 6/30/94 and replaced with a new sensor, S/N 6579. Sensors 6500, 6504, and 6509 have been thrown away, as the manufacturer appears to be incapable of repairing them completely. Rather than waste more money in trying to have them repaired, I ordered three new pressure sensors, of which S/N 6579 is one. Thus, we now have two new sensors as spares.

DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	During two periods recently, the wind direction sensor at E4, Plevna, KS malfunctioned. The first time period was caused by water in the connector to the sensor. The second period was apparently a result of an electronics problem in the sensor circuitry. On June 30, at 1646 GMT sensor S/N 3036 was removed and replaced with S/N 3034. On July 11, at 2003 GMT, sensor S/N 3034 was replaced with S/N 3038. The periods of time listed above are inclusive for the 30 minute data. Slightly less of the 5 and 15 minute values were affected (at the beginning or end of the periods), as is obvious from the sensor replacement times. All of the data should be considered incorrect. The affected data are: 5 minute: res_ws, wind_d, sigma_wd 15 minute: mv_wind_d 30 minute: res_ws, wind_d, sigma_wd

DataStreams:	sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	On 29 November 1995, the Gel Cell battery for the E4 EBBR at Plevna, KS was replaced with a lead acid battery. Gel Cells do not charge or keep a charge in cold weather as well as lead acid batteries. Some data loss and incorrect data resulted. Of the period listed above, the data that is missing and incorrect is listed below. Some data for the incorrect periods is incorrect (sensible and latent heat fluxes), while other data values may be correct (for example: wind speed and direction, soil moisture, etc.) It may be wise to not use any of the 2030 GMT 5, 15, and 30 minute data. 5 minute: missing 1745-2010 GMT incorrect 2015-2030 GMT 15 minute: missing 1745-2000 GMT incorrect 2015-2030 GMT 30 minute: missing 1800-2000 GMT incorrect 2030 GMT

DataStreams:	sgp30ebbrE4.b1, sgp5ebbrE4.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. The period of incorrect data for the EBBR is listed above; data times affected do not include the beginning time and do include the ending time (data files are denoted by the end time).

Description:	On or about 15 May 1996, the anemometer lost two of its three cups in a hailstorm. The exact day that this occurred cannot be determined from the data (9-15 May data is missing). The cups were replaced on 12 June 1996. The first period of good wind speed data is at 1700 GMT on 12 June. All wind speed measurements (including resultant wind speed) are incorrect for the period above.

DataStreams:	sgp30ebbrE4.b1, sgp15ebbrE4.b1, sgp5ebbrE4.b1
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.

DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	A low battery condition (less than 10.5 volts) caused a number of data fields to be incorrect at some times and all data fields to be incorrect at a more limited number of times. All data fields are suspect when the battery voltage drops below 10.5 volts because the CR10 cannot operate properly. Some sensors are affected slightly (i.e. pressure) at slightly larger voltages. The low battery condition resulted from an initially weak battery and a week of extremely low solar radiation (from heavy cloudiness) on the solar panel that provides most of the charging of the battery. Comments added by Marv Wesely: David Cook has been working with Dave Breedlove to try to assess the age of the batteries. The dates on the batteries need to be read during site visits and provided to David C. It's quite possible that they need to be replaced. It's work in progress, though slow at times.

Description:	On 29 April 1998 the battery voltage dropped to below 10.5 volts. No data, except for battery voltage, can be assumed to be correct during this period. The battery was replaced at 1830 GMT. The cause of the problem appears to be a failed solar panel charger/regulator. The voltage of the new battery has dropped steadily since installation; it is apparently not being charged. A work request has been submitted to have the charger/regulator replaced.

Subject:	SGP/EBBR/E4 - EBBR E4 6-Month Checks
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:	During EBBR 6-month checks (formally called 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 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 just before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period above.

Description:	Most of the data for the period is missing. The solar panel regulator was not working, allowing the EBBR battery to slowly and steadily be depleted. The voltage level dropped too low for the system to continue to operate and data was lost or was not measured. A new regulator was installed on 27 May and data collection was resumed.

Subject:	SGP/EBBR/E4 - E4 EBBR Battery Voltage Low
DataStreams:	sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1, sgp5ebbrE4.00
Description:	A blown fuse in the AEM stopped it at a position other than a home position. This created a condition where the battery drained more rapidly than normal, causing the voltage to drop below the acceptable voltage of 10.4 V at times. The 15 minute data shows battery voltage; all 5, 15, and 30 minute data for voltages less than 10.4 volts should be considered to be incorrect.
