SGP/EBBR/E8 - Pressure Sensor Measurements Incorrect

The EBBR barometer did not agree with the SMOS at
all times.  However this problem only rarely affected the 
sensible and latent heat flux values. 

Replacement of the barometer on 29 july 2003, 12 aug 2003,
and 26 aug 2003 caused some obvious disruption in data flow.

SGP/EBBR/E7  - AEM Malfunction, Some Data Incorrect

After a while, the teflon slides on the AEMs warp from
heat and use.  This tends to make the AEM drag, jam, and get hung.
This happened at E7 EBBR.

Replacement of the AEM resolved the problem.

SGP/EBBR/E22 - AEM Home Signals Too High

The AEM home signals were too large at times during the indicated period;
it has been determined by the vendor that this is usually caused by electrical noise in 
the vicinity. When the 30 minute data shows a home 30 signal of 35 or more, the bowen 
ratio, and sensible and latent heat flux 
measurements are incorrect 

Removing the jumper between 4L and AG on the CR10 and adding a jumper to Multiplexer 2, 
Set 6, between L1 and L2 fixed the problem.  The
vendor intends to make this modification to all EBBR systems as they return
for re-calibration.

incorrect net radiation measurements.  However, when it subsequently rains, water collects

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects

SGP/EBBR/E12 - Pressure Sensor Measurement Scales With Battery Voltage

The barometer output was scaling with supply voltage (i.e. it 
               followed the charging of the battery by the solar panel).

               NOTE: The barometer was replaced later than the end date of 
               this DQR.  Why the problem ended on 26 Nov 2003 is unclear; 
               there was no site ops intervention on that date.

               The problem did not affect the sensible and latent heat flux 
               calculations beyond the expected system error.

SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect

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/E7 - Pressure Sensor Data Incorrect

from spikes in pressure, which were related to

were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

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,

SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect

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 - Incorrect soil type coefficients used

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.

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.
