DataStreams:sgp30ebbrE18.a1, sgp30ebbrE18.b1
Description:
Soil Heat Flow 1 was incorrect during the indicated periods.

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

ave_shf = (g2 + g3 + g4 + g5)/4

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

SGP/EBBR/E18 - Data Incorrect After Logger Restart

incorrect.

be calculated using the available, remaining measurements.

SGP/EBBR/E18  - Wind Speed Frozen Stopped By Ice
DataStreams:sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:
An ice storm froze the wind speed sensor to a stopped condition.

The wind speed and residual wind speed measurements are incorrect.

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

SGP/EBBR/E18 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE18.b1
Description:
Effective 20050330.0000, the EBBR.E18 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 20050330, 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 sgp30ebbrE18.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE18.a1).

  • latent_heat_flux
  • sensible_heat_flux
  • surface_soil_heat_flux_avg

SGP/EBBR/E18 - metadata corrections
DataStreams:sgp15ebbrE18.b1, sgp30ebbrE18.b1, sgp5ebbrE18.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E18 data collected by ARM back to the installation of the 
instrument in July 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")
