Subject:	SGP/EBBR/E25 - Reprocess: Soil Heat Flow #5 Negative Offset
DataStreams:	sgp30ebbrE25.a1, sgp30ebbrE25.b1
Description:	Soil heat flow 5 was either too large negative or negative when it should have been positive; the cause of the negative offset is unknown, but is often the result of a failed J-panel over-voltage protection device. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3 + g4)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)

Subject:	SGP/EBBR/E26 - Measurements Incorrect
DataStreams:	sgp30ebbrE26.a1, sgp30ebbrE26.b1
Description:	Change of energy storage (CES) measurements (calculated from the change of soil temperature with time) are sometimes incorrect after a CR10 program restart because the beginning measurement of the averaging period is zero. Average soil heat flow, sensible heat flux, and latent heat flux were affected and cannot be recalculated.

Subject:	SGP/EBBR/E26 - Multiplexer 2 Failure From High Temperature
DataStreams:	sgp5ebbrE26.a1, sgp15ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.a1, sgp30ebbrE26.b1
Description:	Multiplexer 2 is failing during times of control box temperatures above 29 degrees C. 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. The indicated measurements need to be inspected to determine which ones are usable.

Subject:	SGP/EBBR/E26 - Multiplexer Problem
DataStreams:	sgp5ebbrE26.a1, sgp15ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.a1, sgp30ebbrE26.b1
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.

DataStreams:	sgp5ebbrE27.b1, sgp15ebbrE27.b1, sgp30ebbrE27.b1
Description:	Some soil parameters were slightly incorrect since EBBR.E27 was installed in May 2003. While the coefficients were being updated, data collection was suspended resulting in missing data for the specified period. No significant effects (1% or less) on the surface heat flux data would have occurred from using the slightly incorrect coefficients. Therefore, flagging of the surface flux data from the time of installation of E27 is unwarranted.

Subject:	SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
DataStreams:	sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.b1
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.

Subject:	SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
DataStreams:	sgp5ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.b1
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.

Subject:	SGP/EBBR/E27 - Soil Moisture #5 Incorrect
DataStreams:	sgp30ebbrE27.b1
Description:	The wrong CR10 program loaded from the storage module on 9/15/04. During the previous change of program, an attempt was made to store the new program in the storage module; site ops techs did not notice that this attempt failed, leaving the old program in the storage module. When power was cyled on 9/15/04, the old program with flat sm5 coefficients loaded into the CR10. The "flat" coefficients resulted in the sm5 soil moisture hovering around 30%. 15 minute raw sm5 resistances were correct. Average soil heat flow, sensible heat flux, and latent heat flux were not significantly affected and so are not included in the list of incorrect measurements.

DataStreams:	sgp30ebbrE26.b1
Description:	The soil type coefficents for soil moisture were incorrect from the day of the system installation on, making soil moisture values too large. As a result, soil heat flows were overmeasured, and sensible and latent heat fluxes were underestimated.

Subject:	SGP/EBBR/E26 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE26.b1
Description:	Effective 20050331.1700, the EBBR.E26 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 20050331, 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 sgp30ebbrE26.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE26.a1). ~
