The sign was reversed (heat flow plate #1 was installed upside down), causing incorrect 
measurements, as indicated.

2-5.  The recalculated average soil heat flow can then be used to recalculate latent and 
sensible heat fluxes.

SGP/EBBR/E19 - Reprocess: Soil Heat Flow #3 Incorrect

Soil heat flow 3 was incorrect, with values too large positive and too small negative.  
Since the calibration in the program is the one supplied by the vendor, it appears 
that the calibration may be wrong.

Average soil heat flow, sensible heat flux and latent heat flux can be recalculated
using the remaining good sets of soil sensors as follows:
   ave_shf = (g1 + g2 + g4 + g5)/4
   e = -(q + ave_shf)/(1 + bowen)
   h = -(q + e + ave_shf)

SGP/EBBR/E19 - Reprocess: Soil Temperature #3 Incorrect

Soil Temperature 3 was incorrect for the period indicated, causing average soil flow, 
latent heat flux, and sensible heat flux to be incorrect also.

Average soil heat flow, sensible heat flux, and latent heat flux can be recalculated using 
the remaining good sets of soil sensors as follows:

ave_shf = (g1 + g2 + g4 + g5)/4

e = -(q + ave_shf)/(1 + bowen)

Replacement of the CR10 datalogger caused most measurements to be incorrect, reason 
unknown.
A different logger was installed at the end of the specified period and this resolved the 
problem.

SGP/EBBR/E19 - Low Battery Voltage

A battery voltage of less than 10.5 causes many of the sensors to produce incorrect 
measurements.
The 15 minute data contains the battery voltage and should be used to determine whether 
the measurements are usable, based on battery voltage.

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/E19 - REPROCESS: Soil Temperature #3 Incorrect

were being checked. The indicated measurements

also incorrect.

SGP/EBBR/E19 - Pressure Low

The barometric pressure sensor read about 10 mb low during this
period because a lead from the sensor was loose or disconnected.

The error does not affect any other measurements.

• Barometric Pressure(atmos_pressure)

• Barometric Pressure(atmos_pressure)

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/E19 - Change of Energy Storage Incorrect

Because soil temperature measurements were not available 
from the beginning of the half hour, the change in soil 
energy storage could not be calculated and thus is

Sensible Heat Flux (h), and Latent Heat Flux (e) can not 
be calculated using the available, remaining measurements.

SGP/EBBR/E19  - Water in Net Radiometer; Surface Fluxes are Incorrect

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 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

SGP/EBBR/E19 - Tair Right Offscale

The right air temperature data were going offscale.  This

SGP/EBBR/E19 - Battery Voltage Too Low, Most Measurements Incorrect

Battery voltage dropped below levels required to sustain the 
               production of valid data.  The AC charger unit had failed.  
               This prevented charging of the battery during the night and
               prevented the solar panel regulator from properly charging 
               the battery during the day.

SGP/EBBR/E19 - AEM Stuck In One Position, Surface Fluxes Incorrect

SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient

The net radiometer coefficient installed on 2/5/04 for nighttime (negative voltage 
calibration) was incorrect.

Negative net radiations during the subject period can be multiplied by
0.9419 to get corrected net radiation measurements.  The sensible (H)
and latent heat (LE) fluxes (which are very small at night anyway) can
be recalculated using the following equations (where B is Bowen ratio,
Rn is corrected net radiation, and G is soil heat flow):

LE = -(Rn + G)/(B + 1)

H = -(Rn + G + LE)

SGP/EBBR/E19 - Improved EBBR CR10 Program

Effective 20050331.1600, the EBBR.E19 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 sgp30ebbrE19.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE19.a1).

SGP/EBBR/E19 - Average Soil Heat Flux Incorrect

SGP/EBBR/E19 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E19 data collected by ARM back to the beginning of the data 
set in May 1997. 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 type
4) Correction of soil moisture units (from "by volume" to "gravimetric")

SGP/EBBR/E19 - Incorrect Sensible and Latent Heat Fluxes

The gradient measurements and latent and sensible heat fluxes were incorrect because the 
AEM was not exchanging. 

The problem was fixed by replacing the AEM.

SGP/EBBR/E19 - Sensible and Latent Heat Fluxes Incorrect

The sensible and latent heat fluxes were incorrect when the top and bottom air 
temperatures were incorrect.

SGP/EBBR/E19 - Sensible and latent heat flux and net radiation incorrect

Net radiation was too large, resulting in sensible and latent heat fluxes being too large. 
 The cause of the problem is unknown.
