SGP/EBBR/E19  - Water in Net Radiometer; Surface Fluxes are Incorrect
DataStreams:sgp15ebbrE19.a1, sgp15ebbrE19.b1, sgp30ebbrE19.a1, sgp30ebbrE19.b1, sgp5ebbrE19.a1
Description:
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 - Battery Voltage Too Low, Most Measurements Incorrect
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
Battery voltage dropped below levels required to sustain the

               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 - Wind Speed Sensor Frozen Stopped by Ice Storm
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
An ice storm froze the wind speed sensor to a stopped condition.

This sensor failure does not affect the sensible and latent heat fluxes.

SGP/EBBR/E19 - Reprocess: Incorrect Net Rad Calibration Coefficient
DataStreams:sgp30baebbrE19.c1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
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  - Wind Speed Constant
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1

Wind Speed was constant at 5 m/s during this period; the reason is unknown.

This sensor failure does not affect the sensible and latent heat fluxes.

The net radiation measurement was incorrect after the net radiometer cable was chewed by 
rodents.  Sensible and latent heat fluxes were therefore incorrect.

SGP/EBBR/E19 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE19.b1
Description:
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).
Measurements:sgp30ebbrE19.b1:
  • average surface soil heat flow(ave_shf)
  • h(h)
  • latent heat flux(e)

SGP/EBBR/E19 - Average Soil Heat Flux Incorrect
DataStreams:sgp30ebbrE19.b1
Description:
A typo in the version 9 EBBR program caused average soil heat flow to be zero, resulting 
in both sensible and latent heat fluxes being approximately 20 watts per meter squared too 
large during the middle of the day.
Measurements:sgp30ebbrE19.b1:
  • average surface soil heat flow(ave_shf)
  • h(h)

SGP/EBBR/E19 - metadata corrections
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
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")
