SGP/EBBR/E20 - Pressure Sensor Data Incorrect

The E20 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.

were offscale or incorrect on occasion.  Bowen ratio, sensible heat flux, and latent heat 
flux were also incorrect during those times.

Inspection of the data is required to detect the incorrect periods.

were offscale or incorrect on occasion.  Bowen ratio, sensible heat flux, and latent heat 
flux were also incorrect during those times.

• bowen_ratio
• temp_air_bottom

SGP/EBBR/E22 - Net Radiation Incorrect

Rain filled the bottom of the net radiometer with water, resulting
in very high net radiations.  Net radiation is incorrect during this period,
also causing sensible and latent heat fluxes to be incorrect.

• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)
• Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
• Radiation, net(net_radiation)

• Radiation, net(net_radiation)

SGP/EBBR/E27 - Loose Tair Left Connections

Tair left dropped out at times. When this occurred, the sensible and latent heat fluxes 
are incorrect.

Tightening of the electronic connections to the datalogging equipment
appears to have solved the problem.

SGP/EBBR/E20 - Wind Direction Stuck at 100 Degrees

The wind direction sensor was stuck at about 100 degrees.  This did
not affect the primary measurements (net radiation, soil heat flow, sensible heat flux, 
latent heat flux).

SGP/EBBR/E9 - net radiometer top dome broken, water in bottom dome

The Net radiometer top dome was broken.  Site Ops did not indicate that there
was water in the bottom dome, but the data suggests it.  Net radiation values during the 
period are incorrect.

• Radiation, net(net_radiation)
• Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)

• Radiation, net(net_radiation)

SGP/EBBR/E22 - Water In Net Radiometer

Water entered the Net Radiometer through a cracked upper dome, causing the
net radiation values to be too large.  As a result, latent and sensible heat flux values 
are also incorrect.

• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)
• Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)
• Radiation, net(net_radiation)

SGP/EBBR/E7 - Pressure Too High

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.

• Barometric Pressure(atmos_pressure)

SGP/EBBR/E2 - Net Radiometer Dome Broken, Reducing Net Radiation Measurement, Fluxes 
Incorrect

The upper dome of the net radiometer was broken.  Normally this alone does
not affect the net radiation measurement.  However, in this case the 
breakage must have been more than just a bird claw hole or a crack,
resulting in obstruction of the top sensing surface of the net radiometer
and greatly reduced net radiation measurements.

Sensible and latent heat fluxes were reduced as a result.

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.

ts4 went offscale and sm4 dropped to a constant 16% when a "new" program
was installed on 3/30/05.  The wrong program was installed.

Because ts4 did not change with time, it did not mess up the calculation
of e and h.  e and h are slightly overestimated, but only by about 1%,
far less than the system error. This is a rare type of instrument problem where the 
concequences are minimal.

SGP/EBBR/E20 - Improved EBBR CR10 Program

Effective 20050330.1900, the EBBR.E20 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

Prior to 20050330, the improved CR10 program was NOT in effect.  DQRs have

SGP/EBBR/E22 - Improved EBBR CR10 Program

Effective 20050330.1930, the EBBR.E20 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.

SGP/EBBR/E9 - Net Radiation, Sensible and Latent Heat Fluxes Incorrect

The top dome of the net radiometer was broken, resulting in net radiations that were too 
small, and thus sensible and latent heat fluxes that were too small.

SGP/EBBR/E8 - AEM Not Exchanging

The AEM hung in one position frequently and sometimes for many days during this period

While the AEM was not switching, the sensible and latent heat fluxes and gradient 
measurements were incorrect.

SGP/EBBR/E27 - Sensible and Latent Heat Fluxes Incorrect

The left T/RH probe temperature sensor was spiking some of the time during these periods. 
Therefore, sensible and latent heat fluxes were incorrect during parts of the periods as 
well.

SGP/EBBR/E22 - Fluxes Incorrect When Soil Heat Flow #3 Out of Range

When soil heat flow #3 exceeded the range limit in the EBBR program, it was replaced with 
9999es.  This caused the ave_shf and the sensible and latent heat fluxes to be incorrect.
