Subject:	SGP/EBBR/E26 - Multiplexer 2 Failure From High Temperature
DataStreams:	sgp15ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.a1, sgp30ebbrE26.b1, sgp5ebbrE26.a1
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:	sgp15ebbrE26.a1, sgp15ebbrE26.b1, sgp30ebbrE26.a1, sgp30ebbrE26.b1, sgp5ebbrE26.a1
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.

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

DataStreams:	sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1
Description:	An ice storm froze the wind speed sensor to a stopped condition. The wind speed and residual wind speed measurements are incorrect. This sensor failure does not affect the sensible and latent heat fluxes.

Subject:	SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect
DataStreams:	sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.a1
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 - metadata corrections
DataStreams:	sgp15ebbrE26.b1, sgp30ebbrE26.b1, sgp5ebbrE26.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E26 data collected by ARM back to the installation of the instrument in June 1992. 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")
