SGP/EBBR - EBBR E13 Left Aspirator Not Working

A loss of the 12V DC power to the left aspirator caused it to stop
operating.  The affected measurements are:

5 minute:  tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot
15 minute: rr_thum_r, rr_thum_l, mv_hum_r, mv_hum_l, tair_r, tair_l
30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
           vp_top, vp_bot, bowen, h, e

SGP/EBBR - EBBR E13 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

• Sensible heat flux(sensible_heat_flux)
• Net radiation(net_radiation)
• Latent heat flux(latent_heat_flux)

SGP/EBBR/E13 - E13 EBBR Flux Data Incorrect

The Automatic Exchange Mechanism was stuck inbetween the top and bottom positions.  
Incorrect Bowen ratio, and latent and sensible heat fluxes resulted.

Soil Temperature #4 produced noisy measurements, resulting in quantities
calculated from it to be of suspect quality.  This condition normally 
occurred early in the GMT day.  Sensible (h) and latent (e) heat fluxes
were not normally greatly affected.  Average surface heat flow was normally
slightly underestimated.

Soil Temperature #4 floated around, causing average soil heat flow
to sometimes be too small (resulting too small a sensible heat flux and
too large a latent heat flux) or too large (resulting in too large a 
sensible heat flux and too small a latent heat flux).  Investigation of
g4 will indicate when these conditions occurred and the likely effect on

SGP EBBR E13 - E13 EBBR AEM in Mid Position

The AEM stopped before reaching the end of it's travel,
causing the home signals to be between 0 and 3 during 
much of this period (therefore the data is colored yellow).  

All gradient data, sensible heat flux, latent heat flux,
and the Bowen ratio are incorrect during this condition.

The AEM home30 signal is offset by approximately 25;
it appears that the electronics of the AEM is adding
the home15 and home30 voltages together when the AEM is
in the home30 position.

All gradient data, sensible heat flux, latent heat flux,

The AEM stopped before reaching the end of it's travel,
causing the home signals to be between 0 and 3 during 
part of this period.

The AEM home30 signal is offset by approximately 25 
during part of this period; it appears that the electronics 
of the AEM is adding the home15 and home30 voltages 
together when the AEM is in the home30 position.

SGP EBBR E13 - E13 EBBR Left Air Temperature Incorrect

This condition occurred most of the time during the 
indicated period (hence color yellow).

The left air temperature was incorrect only when the AEM
was in the home 30 position.  This only affected the bottom
air temperature calculation.  However, it made the latent
heat flux, sensible heat flux, and Bowen ratio incorrect.

The sensor was improperly inserted into the aspirator shield
and was pinched between the shield and the T/RH probe. When
the AEM was in the home30 position, the aspirator hose
position may have caused the sensor to short to ground.

and was pinched between the shield and the T/RH probe. When
the AEM was in the home30 position, the aspirator hose
position may have caused the sensor to short to ground.

SGP/EBBR/E13 - Reprocess: E13 EBBR Soil Temperature #4 Incorrect

Soil Temperature #4 was often incorrect, typically too large negative,
during this period, causing other measurements calculated with
it to be incorrect also. This was caused by a bad multiplexor channel,
which was discovered by the vendor during recalibration of the unit
later.

SGP/EBBR/E13 - Left T/RH Probe Temperature Incorrect

During much of the indicated period the Left T/RH Temperature was
incorrect.  Because the home signal was between 0 and 3, the 
temperature was incorrect when the AEM was at the bottom position,
but was correct when the AEM was at the top position.  This was caused by
a short created when the sensor was mispositioned in the aspirator
housing and enough strain on the cable for it to bring it into contact
with the housing in the bottom position.

SGP/EBBR/E13 - AEM Hung up

The automatic exchange mechanism hung numerous times, but with various different 
measurements of home signals.  In all cases, temperature and humidity gradients were incorrect; 
thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the 
indicated periods.  Even when the home 15 and 30 signals were different (but too high) the 
measurements were incorrect because the program keys off of the home signals, which must be 
in the proper ranges.

SGP/EBBR/E13 - Improved EBBR CR10 Program

Effective 20050331.2100, the EBBR.E13 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 20050331, 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 sgp30ebbrE13.b1 data stream.  The 
earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. 
sgp30ebbrE13.a1).

• Sensible heat flux(sensible_heat_flux)
• bowen_ratio
• Latent heat flux(latent_heat_flux)

SGP/EBBR/E13 - 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.

SGP/EBBR/E13 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E13 data collected by ARM back to the installation of the 
instrument in September 1992.  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 systems
3) Correction of soil type
4) Correction of soil moisture units (from "by volume" to "gravimetric")

SGP/EBBR/E13 - Radiometer dome broken

The top net radiometer dome was broken, yielding net radiation, sensible heat flux and 
latent heat flux that were too low.

The BEFLUX (SIRS) net radiation can be used as a replacement for the EBBR net radiation.

To correct the sensible and latent heat fluxes, determine the ratio of SIRS net radiation 
to EBBR net radiation for each daylight half hour and multiply that ratio times H and LE 
to obtain approximate corrected flux values.

• Net radiation(net_radiation)

SGP/EBBR/E13 - Net Radiation Too Large

The EBBR Net Radiation (Rn) values maintained a ~200 Wm^-2 reading because of poor cable 
lead connections.  Sensible and latent heat fluxes were therefore overestimated.

Sensible (H) and latent heat (LE) fluxes can be estimated in the following way:

H (new) = H/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation]

LE (new) = LE/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation]

SGP/EBBR/E13 - Reprocess: Incorrect data logger program

The soil moisture data is incorrect. It's likely that the proper procedure was not 
followed during a preventative maintenance visit and an older or an incorrect EF data logger 
program was installed, greatly reducing the soil moisture values.

SGP/MET/E13 - False tips in high winds

The TBRG's were mounted at a height that made them prone to vibrations caused by high 
winds which may have caused false tips.  The end date of this DQR indicates when the rain 
gauge was lowered to mitigate these effects.  

Effects on the total precipitation amounts are assumed to be negligible.

SGP/EBBR/E13 - Frozen Wind Speed Sensor

On February 7, 1997 freezing rain stopped the cups of the EBBR wind 
speed instrument at the Central Facility (E13).  All 5, 15, and 30 
minute data values indicated below are incorrect for the period listed.

SGP/EBBR/E13 - CR10 Malfunction

The CR10 apparently malfunctioned on 17 July 1997.  This caused a variety 
of effects, including incorrect datalogger clock times, missing data 
periods, and some corrupted data fields.  The CR10 was replaced on 
25 July 1997; all data fields are now correct.  Data users may contact
the mentor for more detailed information on data quality during this 
period.

SGP/EBBR/E13 - EBBR Biannual Checks

During EBBR 3 month checks the Automatic Exchange Mechanism is disabled 
(reflected by home signals near zero) so that the two aspirator units
can be placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), 
or latent heat flux (e), nor do the air temperature and relative humidity 
measurements indicate correct gradients.  Checks performed before or after the 
AEM is disabled also lead to some incorrect data.  Incorrect 5, 15 minute and

period.

The calculations of Bowen ratio, latent heat flux, and sensible heat
flux are incorrect for the time period indicated.  The other

SGP/EBBR/E13 - 3-Month Check

During EBBR 3 month checks the Automatic Exchange Mechanism is disabled
(reflected by home signals near zero) so that the two aspirator units can be
placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux
(h), or latent heat flux (e), nor do the air temperature and relative 
humidity measurements indicate correct gradients.  Checks performed before 
or after the AEM is disabled also lead to some incorrect data.  Incorrect 5,

SGP/EBBR/E13 - Six Month Checks

During EBBR 6 month checks (formally called 3 month checks) the Automatic 
Exchange Mechanism is disabled (reflected by home signals near zero) so that
the two aspirator units can be placed at the same height.  The measurements
during these periods do not produce correct outputs of bowen ratio (bowen), 
sensible heat flux (h), or latent heat flux (e), nor do the air temperature
and relative humidity measurements indicate correct gradients.  Checks 
performed just before or after the AEM is disabled also lead to some 
incorrect data.  Incorrect 5, 15 minute and half hour data occurs for the 
period indicated.

SGP/EBBR/E13 - Net Radiation Incorrect - Water in Bottom Dome

Water entered the net radiometer top dome through a hole made, probably,
by migrating birds (this happens every Spring and Autumn) and accumulated
in the bottom dome.  This causes nighttime net radiations to be too large
and daytime net radiations to be too small.  The data is therefore incorrect.
