flow, latent heat flux and sensible heat flux.  The heat fluxes can be recalculated by using

SGP/EBBR/E26 - Multiplexer 2 Failure From High Temperature

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/E9 - Right Humidity Suspect

The Right Humidity measurement was normally incorrect, although it is often difficult to 
determine it by looking at the measurement.  The measurements float around, sometimes 
being too large and sometimes being too small, through most of the day, particularly for the 
hour before sunset through the hour after sunrise.  Great care and comparison with 
surrounding EBBR sites would be needed to be able to use any of the latent and sensible heat 
flux measurements from E9 for this period. 

Another DQPR has been issued to fix this problem, which has eluded repair efforts so far.

SGP/EBBR/E12 - Reprocess: Soil Temperature #3 Incorrect

Soil Temperature #3 was flaky primarily during nighttime hours and sometimes during early 
daylight hours.  Average soil heat flow, sensible heat flux, and latent heat flux are 
also affected; these can be recalculated using the remaining good sets of soil sensors as 
follows:

The heat fluxes can be recalculated by using soil sets 1, 2, 4, and 5 as follows:

SGP/EBBR/E12 - Wind Direction Incorrect

SGP/EBBR/E15 - REPROCESS: Soil Moisture #1 Offset

The wrong offset (9.5264) was used in the calibration coefficients for

SGP/EBBR/E15 - Wind Direction 10 Degrees Low

The wind direction at E15 EBBR was 10 degrees low for the period (since
installation of the EBBR unit on 10/11/01). The wind direction sensor was apparently 
aligned to magnetic north instead of true north at installation.

SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect

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

SGP/EBBR/E13 - Improved EBBR CR10 Program

Effective 20050331.2100, the EBBR.E13 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 sgp30ebbrE13.b1 data stream.  The 
earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. 
sgp30ebbrE13.a1).

SGP/EBBR/E26 - Improved EBBR CR10 Program

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).
