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.

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.

SGP/EBBR/E26 - Multiplexer Problem

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.

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.

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).

SGP/EBBR/E26 - metadata corrections
DataStreams:sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.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")
Measurements:sgp15ebbrE26.b1:
  • Time offset from base_time(base_time)

sgp5ebbrE26.b1:
  • Time offset from base_time(base_time)
