SGP/EBBR - EBBR E12 Anemometer Cups Frozen, Wind Speed Incorrect

The anemometer cups were frozen stalled during this period.

The following values were therefore incorrect:

5 minute:  wind_s, res_ws
15 minute: wind_s
30 minute: wind_s, res_ws

• Wind speed, lower, 1-min avg(wspd_arith_mean)

• Wind speed vector mean(wspd_vec_mean)
• Wind speed, lower, 1-min avg(wspd_arith_mean)

• Wind speed, lower, 1-min avg(wspd_arith_mean)
• Wind speed vector mean(wspd_vec_mean)

SGP/EBBR - EBBR E12 Net Radiation Incorrect

Condensation inside the domes (possibly water in the bottom dome also) 
during the period made daytime net radiation values as much as 50% too 
large and nighttime net radiations as much as 100% too small.  

The affected data are:

5 minute:  q
15 minute: mv_q
30 minute: q, h, e

• 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)

• net_radiation_mv

• Radiation, net(net_radiation)

SGP/EBBR - EBBR E12 Net Radiation Incorrect

The net radiometer top dome was broken and water had entered.  Net 
radiation values are therefore incorrect during the period.

The affected data are:

5 minute:  q
15 minute: mv_q
30 minute: q, h, e

• 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)

• net_radiation_mv

• Radiation, net(net_radiation)

SGP/EBBR/E12 - EBBR E12 Wind Speed Iced

The anemometer was frozen stopped by freezing rain; the indicated data is incorrect.

• Wind speed vector mean(wspd_vec_mean)
• Wind speed, lower, 1-min avg(wspd_arith_mean)

• Wind speed, lower, 1-min avg(wspd_arith_mean)

The wind direction vane was frozen stopped in one direction by icing.

• Wind speed vector mean(wspd_vec_mean)
• Wind direction, vector, lower, 1-min avg(wdir_vec_mean)
• wdir_vec_std

• wdir_vec_mean_mv

• Wind speed, lower, 1-min avg(wspd_arith_mean)

• Wind speed vector mean(wspd_vec_mean)
• Wind speed, lower, 1-min avg(wspd_arith_mean)

• Wind speed, lower, 1-min avg(wspd_arith_mean)
• Wind speed vector mean(wspd_vec_mean)

SGP/EBBR/E12 - Reprocess: Soil Temperature #3 Incorrect

Soil Temperature #3 was flaky primarily during nighttime hours and sometimes during early 
daylight hours.  Average soil heat flow, sensible heat flux, and latent heat flux are 
also affected; these can be recalculated using the remaining good sets of soil sensors as 
follows:

The heat fluxes can be recalculated by using soil sets 1, 2, 4, and 5 as follows:
     ave_shf = (g1 + g2 + g4 + g5)/4
     e = -(q + ave_shf)/(1 + bowen)
     h = -(q + e + ave_shf)

SGP/EBBR/E12 - Reprocess: Soil Moisture 4 and 5 Incorrect

Soil moisture measurements from sets 4 and 5 were incorrect, leading to many other 
incorrect measurements calculated using them.

Average soil heat flow, sensible heat flux, and latent heat flux are affected; these can 
be recalculated using the remaining good sets of soil sensors as follows:
    ave_shf = (g1 + g2 + g3)/3
    e = -(q + ave_shf)/(1 + bowen)
    h = -(q + e + ave_shf)

Note:  D020717.6 reports Soil temperature sensor #3 was also bad during this
time, but for the very specific records affected by the soil moisture #4 and
#5 reporting incorrectly, soil temp #3 was okay.  Therefore the equations
given are correct.

SGP/EBBR/E12 - Reprocess: Soil Moisture 2 and 5 Incorrect

Soil moisture measurements from sets 2 and 5 were incorrect, leading to many other 
incorrect measurements calculated using them.

Average soil heat flow, sensible heat flux, and latent heat flux are affected; these can 
be recalculated using the remaining good sets of soil sensors as follows:
    ave_shf = (g1 + g3 + g4)/3
    e = -(q + ave_shf)/(1 + bowen)
    h = -(q + e + ave_shf)

Note:  D020717.6 reports Soil temperature sensor #3 was also bad during this
time, but for the very specific records affected by the soil moisture #2 and

SGP/EBBR/E12  - Water in Net Radiometer, Surface Fluxes 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/E12 - Pressure Sensor Measurement Scales With Battery Voltage

The barometer output was scaling with supply voltage (i.e. it 
               followed the charging of the battery by the solar panel).

               NOTE: The barometer was replaced later than the end date of 
               this DQR.  Why the problem ended on 26 Nov 2003 is unclear; 
               there was no site ops intervention on that date.

               The problem did not affect the sensible and latent heat flux 
               calculations beyond the expected system error.

SGP/EBBR/E12 - Improved EBBR CR10 Program

Effective 20050329.1830, the EBBR.E12 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 20050329, 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 sgp30ebbrE12.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE12.a1).

• Average soil heat flow at the surface(surface_soil_heat_flux_avg)
• 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)

SGP/EBBR/E12 - Average Soil Heat Flux Incorrect

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.

• Average soil heat flow at the surface(surface_soil_heat_flux_avg)
• 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)

SGP/EBBR/E12 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E12 data collected by ARM back to the installation of the 
instrument in August 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 type
4) Correction of soil moisture units (from "by volume" to "gravimetric")

SGP/EBBR/E12 - Sensible and Latent Heat Fluxes Incorrect at Times

Large spikes in soil temperature #2 are causing the soil heat storage
term to blow up, and thus the average soil heat flow, sensible heat flux, 
and latent heat flux to be incorrect at times.

• soil_temp_2_rr

incorrect.

SGP/EBBR/E12 - Net Radiation, and Sensible and Latent Heat Fluxes Incorrect

Rain entered into the net radiometer through a broken top dome.  Most of the net radiation 
values during the period are much too large, thus sensible and latent fluxes are also 
too large.

SGP/EBBR/E12 - Wind Direction Dependency of Surface Fluxes and General Data Quality 
Information

Beginning in FY2006, Data Quality Reports are not written for missing 
data or for situations when qc flags clearly show that the data is 
incorrect (this is true for most of the conditions listed below).  
DQRs are written for periods when data is incorrect, when the situation 
is not represented by qc flags in the data, and it's not obvious that 
the data should have been flagged as incorrect.

The EBBR data is only useful for particular wind directions at each 
Extended Facility.  Please use the following resources to help in 
interpreting the EBBR data.

1) qc flags in the EBBR data.

2) Instrument Mentor Monthly Summaries (IMMS) at http://www.db.arm.gov/IMMS/

3) SGP EF Surface Conditions Observations (EFSCO) at 
http://198.124.96.210:591/sfc_cond1/default.htm

4) Surface fluxes are valid only for the following wind directions
(in degrees):

0-360

Note that there are wind directions at most sites for which the fetch
is insufficient and therefore EBBR data is invalid.  Appropriate 
fetch was determined from a 1/40 measurement height to fetch ratio, 
resulting in a required minimum fetch of 120 m.  Particular attention 
should be paid to the limited valid wind directions for the Central 
Facility EBBR.	The surface vegetation type for the EBBRs is grazed 
or ungrazed grassland (refer to the EFSCO for state).

5) Some conditions that commonly cause the EBBR primary measurements to 
be incorrect or missing follow:

a) Sensible and latent heat fluxes are not accurate during times when 
the Automatic Exchange Mechanism (AEM) is not functioning properly.  
The AEM switches the gradient measuring instrumentation between the 
top and bottom positions every 15 minutes; this reduces the effects of 
instrument offsets.  Sometimes the AEM does not reach it's full extent 
of travel, resulting in the home signal being zero.  

b) Sensible and latent heat fluxes are sometimes incorrect when surface 
soil heat flow is out of range, as seen in the average soil heat flux 
(ave_shf).

c) Very light winds may be seen at nights for brief periods. Wind 
direction flops around a lot during low wind conditions (< 1.5 m/s) 
and is often unreliable during those periods.

d) Missing data periods occur at times; this is usually a site data 
system collection/communication problem; it can also occur during 
replacement of the system with a newly calibrated unit.  Missing data 
is sometimes filled in later from manual or automatic re-collection of 
the data.

SGP/EBBR/E12 - Intermittent data loss

The datalogger at E12 EBBR reset it's time to Dec 3, 1999 on a periodic basis.  This 
occurred on 5/3, 5/15, 5/17, 5/18, 5/27, 6/5 and 6/6 of 2010. Each time this occurred we lost 
1-2 hours of data.

The datalogger was apparently at fault.  The problem has not re-occurred since the 
datalogger was replaced on 6/8/2010.

SGP/EBBR/E12 - RH top Data Zero

The one data value hum_top was incorrect in the 30 minute data.  5 and 15
minute data were not affected, and the 30 minute flux data was not affected.
The data value may have been lost in remote data retrieval, resulting in
a zero value instead.
