SGP/EBBR/E4 - Soil Temperature #5 Spiking Upwards
DataStreams:sgp30ebbrE4.b1
Description:
Soil temperature #5 experienced some erratic behavior during nighttime, spiking upwards 
slightly at times (mouse activity?).  This caused soil moisture #5 to be corrected 
downwards very slightly.
Measurements:sgp30ebbrE4.b1:
  • 0-5 cm integrated soil temperature, site 5(ts5)
  • volumetric soil moisture, site 5(sm5)

SGP/EBBR/E4 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE4.b1
Description:
Effective 20050323.1800, the EBBR.E4 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 20050323, 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 sgp30ebbrE4.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE4.a1).
Measurements:sgp30ebbrE4.b1:
  • h(h)
  • average surface soil heat flow(ave_shf)
  • latent heat flux(e)

SGP/EBBR/E4 - Average Soil Heat Flux Incorrect
DataStreams:sgp30ebbrE4.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:sgp30ebbrE4.b1:
  • h(h)
  • average surface soil heat flow(ave_shf)
  • latent heat flux(e)

SGP/EBBR/E4 - metadata corrections
DataStreams:sgp15ebbrE4.b1, sgp30ebbrE4.b1, sgp5ebbrE4.b1
Description:
On 20050817, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E4 data collected by ARM back to the installation of the 
instrument in April 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")
