SGP/EBBR/E27  - 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/E27 - Missing data during system update

Some soil parameters were slightly incorrect since EBBR.E27 was 
                 installed in May 2003.  While the coefficients were being updated,
                 data collection was suspended resulting in missing data for the 
                 specified period.
                    No significant effects (1% or less) on the surface heat flux data 
                 would have occurred from using the slightly incorrect coefficients. 
                 Therefore, flagging of the surface flux data from the time of 
                 installation of E27 is unwarranted.

SGP/EBBR/E27 - Soil Moisture #5 Incorrect

The wrong CR10 program loaded from the storage module on 9/15/04.  During the previous 
change of program, an attempt was made to store the new program in the storage module; site 
ops techs did not notice that this attempt failed, leaving the old program in the storage 
module.  When power was cyled on 9/15/04, the old program with flat sm5 coefficients 
loaded into the CR10.  The "flat" coefficients resulted in the sm5 soil moisture hovering 
around 30%.

15 minute raw sm5 resistances were correct.

Average soil heat flow, sensible heat flux, and latent heat flux were not
significantly affected and so are not included in the list of incorrect measurements.

SGP/EBBR/E27 - Improved EBBR CR10 Program

Effective 20050330.1730, the EBBR.E27 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 sgp30ebbrE27.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE27.a1).

caused the net radiation measurements to be biased low, and resulting in sensible and 
latent heat flux being low also.

SGP/EBBR/E27 - Average Soil Heat Flux Incorrect

large during the middle of the day.

SGP/EBBR/E27 - metadata corrections

On 20050816, a series of metadata corrections and additions were completed.  These

instrument in May 2003. Please see the current metadata for correct information.  These 
changes do not affect data values or quality.
