SGP/EBBR/E7 - Soil Heat Flow #5 Incorrect
DataStreams:sgp15ebbrE7.a1, sgp15ebbrE7.b1, sgp30ebbrE7.a1, sgp30ebbrE7.b1
Description:
Soil Heat Flow Plate #5 data was intermittently incorrect at first 
(values too small negative), then was almost constantly so during the 
last half of the period.

Comparison of the individual soil heat flows will quickly show the times
that soil heat flow #5 was incorrect.

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/E7 - Pressure Sensor Data Incorrect
DataStreams:sgp5ebbrE7.a1, sgp15ebbrE7.b1, sgp30ebbrE7.b1
Description:
The E7 pressure sensor suffered
from spikes in pressure, which were related to 
increases in voltage during the day as the 
solar panels charged the battery.  These spikes
were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

Description:
When data collection resumed after a missing period, the barometer pressure
had become very high, 102 kPa, which was not correct.  This condition resulted
from an incorrect calibration being used. Sensible heat flux was overestimated 
by about 4% and latent heat flux underestimated by about 4% because of the 
high pressure readings.

SGP/EBBR/E7 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE7.b1
Description:
Effective 20050322.1900, the EBBR.E7 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 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 sgp30ebbrE7.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE7.a1).
Measurements:sgp30ebbrE7.b1:
  • average surface soil heat flow at the surface(ave_shf)
  • corrected sensible heat flux(h)
  • latent heat flux(e)

SGP/EBBR/E7 - metadata corrections
DataStreams:sgp5ebbrE7.b1, sgp15ebbrE7.b1, sgp30ebbrE7.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E7 data collected by ARM back to the installation of the 
instrument in May 1993. 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 moisture units (from "by volume" to "gravimetric")
Measurements:sgp5ebbrE7.b1:
  • Time offset from base_time(base_time)
sgp30ebbrE7.b1:
  • Time offset from base_time(base_time)
sgp15ebbrE7.b1:
  • Time offset from base_time(base_time)
