SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR 
Header

The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the 
EBBR 30 minute netcdf header have been incorrect from the beginning 
of processing the data into netcdf files.  The correct units are 
MJ/m^3/C.

This does not affect the data quality.

SGP/EBBR/E20 - REPROCESS: Soil Temperature #2 Incorrect

from am loose wire after replacement of the EBBR unit.
The indicated measurements that are calculated using 
soil temperature are also incorrect.

See the work-around below.

SGP/EBBR/E19 - Soil Temperatures #2 and #3 Intermittently Bad

Soil Temperatures #2 and #3 were intermittently incorrect.
#3 appeared to be okay after the J-panel was replaced. 
#2 continues to be flaky, suggesting that the sensor
itself has a problem.  A DQPR has been submitted to
replace #2.  The indicated measurements 
that are calculated using soil temperature are 
also suspect.  However, the intermittent problems normally
occurred during night times and were fairly small in magnitude,
thereby having little effect on the sensible and latent heat fluxes.

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.

The latitude, longitude and altitude of the El Reno (E19) site were
incorrectly entered into the ARM database.  The correct location

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).

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 20050322, 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 sgp30ebbrE8.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE8.a1).

SGP/EBBR/E9 - Improved EBBR CR10 Program

Effective 20050322.1600, the EBBR.E9 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.

measurements of h and e.
