The failure begins in the last channel and progresses to lower channels as the temperature increases. It has not yet been determined whether the failure is in the relays or a solid state component of the multiplexer. This condition is probably due to the aging of the device and the millions of cycles that this 10 year old device has made. More failures of this sort may occur in the future. A cure is being sought aside from replacement of the multiplexers to prevent the problem.

It helps to remember that the multiplexer behavior is temperature dependent. QUALITY COLOR: Red - Incorrect PRB REVIEWED: Y ---------------------------------------- DQR DESCRIPTION: One of the multiplexers exhibited dropouts of the channels, beginning with the last channel at temperatures above about 30 C and moving backward through the channels as the temperature rose. High temperatures affected the switching speed of the multiplexer. This is the first time that this behavior has been documented in a Campbell Scientific multiplexer. The multiplexer had been in continuous field use for 10 years and had experienced probably more switching cycles than what is normally expected of the device in that period. The multiplexer was replaced to solve the problem. ---------------------------------------- DQR DATASTREAM(S): sgp15ebbrE26.a1 tair_l tair_r sgp15ebbrE26.b1 tair_l tair_r sgp30ebbrE26.a1 ave_shf c_shf1 c_shf2 c_shf3 c_shf4 c_shf5 e g1 g2 g3 g4 g5 h tair_bot tair_top sgp30ebbrE26.b1 ave_shf c_shf1 c_shf2 c_shf3 c_shf4 c_shf5 e g1 g2 g3 g4 g5 h tair_bot tair_top sgp5ebbrE26.a1 tair_bot tair_top START DATE/TIME: 07/01/2002 00:00 GMT END DATE/TIME:07/11/2002 13:00 GMT ---------------------------------------- LINK(S): none

These spikes were not of a magnitude that would affect the 30 minute surface fluxes. Replacement of the pressure sensor solved the problem. ---------------------------------------- DQR DATASTREAM(S): sgp15ebbrE7.b1 mv_pres sgp30ebbrE7.b1 pres sgp5ebbrE7.a1 pres START DATE/TIME: 03/07/2003 15:00 GMT END DATE/TIME:10/12/2003 23:55 GMT ---------------------------------------- LINK(S): DQR ID: D040206.3 - SGP/EBBR/E7 - Pressure Sensor Data Incorret DQPR: DQPR 180

DQR ID: D041004.4 DQR SUBMITTER: David Cook DATE SUBMITTED: 10-04-2004 DQR SUBJECT: SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect SUGGESTIONS: There is no easy work around to this problem. Using an average of soil moisture at surrounding EBBR sites may be useful. QUALITY COLOR: Red - Incorrect PRB REVIEWED: Y PRB DISCUSSION: 10/12/2004: reprocessing not recommended. ---------------------------------------- DQR DESCRIPTION: The soil Moisture coefficients used for E15 were incorrect from the time of installation of the system in program version 8. On 9 July 02 parameter 4 (an offset value) of program step 136 was changed from 9.5264 to the correct value 0.95264 (this error had been made by the vendor). The error masked the real problem (wrong soil type) and after 9 July 02 resulted in very low soil moisture measurements. The coefficients used were for coarse sand. On 28 Sep 04 I visited the E15 site and found the soil type a fine sandy clay or fine sandy loam. I changed the coefficients at 1509 GMT to those for a very fine sandy loam; this produced reasonable soil moistures for the soil type. The old coefficients in parameters 4 through 9 for step 136 of the program were: 0.95264, -6.7859, 36.224, -58.619, 25.073, 4.2278 The new coefficients are: 10.241, -27.943, 49.523, -12.648, -52.643, 38.054 ---------------------------------------- DQR DATASTREAM(S): sgp30ebbrE15.b1 ave_shf ces1 ces2 ces3 ces4 ces5 e g1 g2 g3 g4 g5 h sm1 sm2 sm3 sm4 sm5 START DATE/TIME: 10/11/2001 15:00 GMT END DATE/TIME:09/28/2004 15:09 GMT ---------------------------------------- LINK(S): none
DQR ID: D041222.1 DQR SUBMITTER: David Cook DATE SUBMITTED: 12-22-2004 DQR SUBJECT: SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect SUGGESTIONS: QUALITY COLOR: Red - Incorrect PRB REVIEWED: Y ---------------------------------------- DQR DESCRIPTION: In a trip to E26, I found that a bad spark gap through which the barometer was powered was causing pressure measurements to be incorrect. The pressure readings oscillated with the voltage of the EBBR battery. During daytime the voltage and thus the pressure would increase and vice versa during dark hours. Apparently only the positive side of the power supply was properly connected through the spark gap and thus the voltage received by the pressure sensor was lower than required to power it properly. Under this condition the perssure measurement varies with voltage level. The pressure measurements therefore had a diurnal signature and usually were incorrect. The decreased pressure during most times would cause latent heat flux to be slightly overestimated and sensible heat flux to be slightly underestimated. ---------------------------------------- DQR DATASTREAM(S): sgp15ebbrE26.b1 mv_pres sgp30ebbrE26.b1 bowen e h pres sgp5ebbrE26.a1 pres START DATE/TIME: 03/21/2003 15:30 GMT END DATE/TIME:10/12/2003 23:55 GMT ---------------------------------------- LINK(S): DQR ID: D031211.3 - SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
