SGP/EBBR - EBBR E19 Wind Speed Incorrect

The anemometer cups were frozen stalled during the 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, 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 vector mean(wspd_vec_mean)

SGP/EBBR - EBBR E15 Anemometer Cup Off, Wind Speed Incorrect

An anemometer cup fell off.

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 vector mean(wspd_vec_mean)

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

SGP/EBBR- EBBR E15 Air Temperatures Incorrect

When the reference temperature sensor was being replaced, the left and
right thermocouple air temperatures and humidity probe temperatures 
were incorrect.

Affected data values were:

5 Minute:  tref, tair_top, tair_bot, thum_top, thum_bot, vp_top, vp_bot
15 minute: rr_tref, rr_thum_l, rr_thum_r, tair_r, tair_l
30 minute: tref, tair_top, tair_bot, thum_top, thum_bot, vp_top, vp_bot,

SGP/EBBR - EBBR E18 Right Humidity Incorrect

After the 3 December 99 lightning strike, the humidity portion of the 
right T/RH probe drifted downwards at times, causing vapor pressure 
gradients to be incorrectly measured.  Therefore, sensible and latent
heat fluxes were also incorrect.  Since much of the data from the period
is missing (because of latent effects of the lightning strike), little
data is actually affected. 

The affected data values were:

5 minute:  hum_top, hum_bot, vp_top, vp_bot
15 minute: mv_hum_r
30 minute: hum_top, hum_bot, vp_top, vp_bot, bowen, h, e

SGP/EBBR - EBBR E18 Data Incorrect After Lightning Strike

Immediately after the 3 December 99 lightning strike, all data from this 
EBBR system was incorrect.  The system crashed at the end of this period.

The sign was reversed (heat flow plate #1 was installed upside down), causing incorrect 
measurements, as indicated.

The average soil heat flow can be recalculated by using an average of soil sensor sets 
2-5.  The recalculated average soil heat flow can then be used to recalculate latent and 
sensible heat fluxes.

SGP/EBBR/E15 - T/RH Check

During the month of November 1994, site operations personnel conducted
field comparisons of the temperature and relative humidity sensors in the
EBBRs and the HMI31 portable T/RH meter (with the removable probe).  As is
reflected in the home signal output, the automatic exchange mechanism was
disabled in order to conduct the checks.

Measurements were taken every 5 minutes, for a half hour each in the
aspirated radiation shields (the HMI31 was inserted into the EBBR aspirated
radiation shield to provide the same aspiration as the EBBR sensors
received).  Measurements of aspirator flow were also recorded.  This
information was provided to the mentor.  The mentor then compared the field
checks with the data recorded by the EBBRs.

The periods of data and data fields that are incorrect because of the checks
are listed below.  Times are those at which the data are reported.


Data Fields

30 minute: 1700, 1730, 1800, 1830

(EDITOR'S NOTE:  The following analysis refers to all EBBRs installed in Nov 1994)

Results of the T/RH comparisons:
The combined accuracy of the HMI31 and EBBR temperature sensors
(thermocouples or PRTDs) is +/- 0.4 degrees C.  The combined accuracy of the
HMI31 and EBBR RH sensors is +/- 4% for RH less than 80%, and +/- 6% for RH
greater than 80%.  The combined accuracy for each pair of EBBR sensors of
the same type is essentially the same as the quantities stated above.

All of the pairs of EBBR sensors show differences that fall within the
stated combined accuracies.  Although this sounds wonderful, a few of the
differences are close to the combined accuracy, which, because of the small
differences in temperature being measured (normally smaller than the
magnitude of the combined accuracy) could lead to some incorrect estimation
of sensible and latent heat flux.  However, unless there would be substantial
differences of calibration slope of two sensors in a pair, the switching of
height of the sensors every 15 minutes by the automatic exchange mechanism
will remove the offset between the sensors.

The comparisons between the EBBR sensors and the HMI31 T/RH meter showed
much larger differences.  The range of differences were: -2.4 to 0.0 degrees
for the thermocouples, -2.1 to 0.1 degrees for the RH probe PRTDs, and -6.6 to
6.7 percent for the RH sensors.  Six Thermocouples indicated differences from
the HMI31 greater than the combined accuracy.  Seven PRTDs indicated
differences from the HMI31 greater than the combined accuracy.  Four RH
sensors indicated differences from the HMI31 greater than the combined
accuracy.  The temperature differences (for both thermocouples and PRTDs)
were nearly all of one sign; the HMI31 indicated the greater temperature,
which may suggest a bias in the HMI31 temperature measurement, even though
a dozen differences of +/- 0.2 degrees were measured.  Four differences of
zero and only one positive difference (out of 40) were measured.  Thirteen of
the 20 RH differences were positive (HMI31 indicating the lower
RH), with the differences near the level of the combined accuracies being
approximately 50% positive and 50% negative.  It does not appear that the
HMI31 has a RH bias.

Plots of EBBR sensor/HMI31 differences as a function of time from the
installation of the individual sensors (a range of 10 to 30 months in the
field) shows no obvious pattern of sensor drift with time.  This is encouraging.

SGP/EBBR/E15 - 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 this period, at least,
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 gradients.  Checks performed before or after the AEM
is disabled also lead to some incorrect data.

SGP/EBBR/E19 - Reprocess: Soil Heat Flow #3 Incorrect

Soil heat flow 3 was incorrect, with values too large positive and too small negative.  
Since the calibration in the program is the one supplied by the vendor, it appears 
that the calibration may be wrong.

Average soil heat flow, sensible heat flux and latent heat flux can be recalculated
using the remaining good sets of soil sensors as follows:
   ave_shf = (g1 + g2 + g4 + g5)/4
   e = -(q + ave_shf)/(1 + bowen)

SGP/EBBR/E19 - Pressure Incorrect

The pressure measurement was incorrect.  This is used to determine the Bowen ratio, 
thereby affecting the sensible and latent heat fluxes also.

• Barometric Pressure(atmos_pressure)

• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)
• Barometric Pressure(atmos_pressure)
• Heat flux, sensible, at 1.5-m height, 30-min intervals(sensible_heat_flux)

SGP/EBBR/E19 - Measurements Incorrect After CR10 Replacement

Replacement of the CR10 datalogger caused most measurements to be incorrect, reason 
unknown.
A different logger was installed at the end of the specified period and this resolved the 
problem.
