SGP/EBBR/E26 - Temperature from Left T/RH Probe Incorrect

The temperature from the left T/RH probe went offscale frequently.  This
temperature is used in the calculation of the vapor pressure.  Therefore,
top and bottom Thum measurements, left Thum, top and bottom vapor pressure 
measurements, vapor pressure gradients, and the resulting latent and 
sensible heat fluxes and bowen ratio were frequently incorrect for the 
period stated.

SGP/EBBR - EBBR E22 Moved, Data Missing/Incorrect

During, and as a consequence of, the relocation of E22 EBBR, some data
is missing or incorrect during the period above.  The data was 
sneakernetted on 3 Nov 99, so some of the data may have been recovered.
Some of the data during the period is incorrect as a consequence of
damage done by cattle during the period; inspection of the data is
required to determine incorrect data.

SGP/EBBR - EBBR E22 Net Radiation Incorrect

The upper dome of the net radiometer was broken, probably by migrating
birds, and water had drained into the bottom dome.  Since much of the data
is missing during the period, it is not clear exactly when the top dome was
broken during the period.  All net radiation data and sensible and latent 
heat fluxes data are incorrect for this period.

The affected data fields are:

5 minute:  q

15 minute: mv_q

30 minute: q, e, h

• Heat flux, latent, at 1.5-m height, 30-min intervals(latent_heat_flux)

Left T/RH probe temperature is frequently offscale during the period.
Examine the data (compare with the the T/RH right temperature) to determine
which times are incorrect.  Replacement of the probe on 29 June 1999 
solved the problem.

SGP/EBBR - EBBR E4 Data Incorrect When Batt. Volt. Under 10.4 V

All data was incorrect when the battery voltage dropped below 10.4 volts.
An old battery was the cause of the problem; it had no deep cycle charge
capacity.

SGP/EBBR - EBBR E4 Soil Heat Flux Values Too Large

flux values output were larger than what could be considered reasonable, 
for unknown reasons.

The following values were therefore incorrect as a result:

The anemometer cups were frozen stalled during the period.

The following values were therefore incorrect:

SGP/EBBR/E26 - Anemometer Not Working, Wind Speed Incorrect

The anemometer was not working during this period.

The following values were therefore incorrect:

15 minute: wind_s
30 minute: wind_s, res_ws

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

SGP/EBBR/26 - Low Battery Condition

When battery voltage was less than 10.4 V DC during this period, all

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 E8 Left Air Temperature (thermocouple) Incorrect

The left air temperature (thermocouple) frequently went offscale, for an
unknown reason, thereby affecting many quantities.

15 minute: tair_l
30 minute: tair_bot, tair_top, bowen, h, e

SGP/EBBR - EBBR E8 Wind Direction Incorrect

A malfunctioning wind direction sensor caused the wind direction 
measurement to be incorrect for the period.

SGP/EBBR - EBBR E22 Soil Moistures Negative

Because of the lack of rain, soil moistures were negative during much 
of the period.  All five soil moisture sensors had negative outputs by 
early on Aug 1.  The negative soil moistures affected sensible and latent
heat fluxes slightly.

The affected data are:

SGP/EBBR - EBBR E19 Net Radiation Incorrect

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

SGP/EBBR - EBBR E22 Soil Moistures Negative

Because of the lack of rain, all soil moistures were negative during much 
of the period.  The negative soil moistures caused soil heat storage and
thus average soil heat flux to be smaller than they should have been.  The
sensible and latent heat fluxes were therefore reduced slightly 
(approximately 0-5%).

The affected data are:

15 minute: r_sm1, r_sm2, r_sm3, r_sm4, r_sm5

SGP/EBBR/E26 - Reprocess Soil Moisture Off-Scale

During numerous periods within the days listed above, individual soil
moisture probes indicate small positive or else negative values when
soil moisture is high (greater than 35%).  This situation has occured
since the present EBBR unit was installed on 17 July 1996.  The cause
of the problem is inadequate range in the calibration curve equation.
Cement soil is somewhat unique amongst the EBBR sites, as the soil is
very sandy and porous; it can hold a larger amount of water per volume
than the other soils.  This high a soil moisture cannot be obtained with
the calibration soil used by REBS.  Therefore, the soil moisture equations
need to be manipulated to allow larger soil moistures to be calculated.
Much of the data from January 1998 is corrupted by this problem,
making changes in the equations prudent.

The soil moisture data must be inspected by the data user to see when
soil moisture values for one or more probes is inconsistent with the
others.

Recalculation of ave_shf, e, and h must be made using only the soil
moisture sets with correct soil moisture values.
Affected data values are (# for probe number):

15 minute: rr_sm#

30 minute: sm#, c_shf#, cs#, ces#, g#, ave_shf, e, h

Sensible, latent, and soil heat fluxes can be recalculated using the soil
probe sets that provide correct data.  For example, if soil moisture 2 is
incorrect,

ave_shf = (g1 + g3 + g4 + g5)/4

e = -(q + ave_shf)/(1 +bowen)

h = -(e + ave_shf +q),


If soil moisture 2 and 4 are incorrect,

ave_shf = (g1 + g3 + g5)/3

e = -(q + ave_shf)/(1 +bowen)

h = -(e + ave_shf +q),


If soil moisture 2, 4, and 5 are incorrect,

ave_shf = (g1 + g3)/2

e = -(q + ave_shf)/(1 +bowen)

h = -(e + ave_shf +q),

etc.

On 5 May 1998 at 1815 GMT a calibration coefficient was changed in the CR10
program as a result of a BCR by the mentor.  This coefficient has helped
reduce the least severe problems but has not eliminated problems from
large negative soil moistures measured even once during the integration
period.  However, now the incorrect average soil heat flow, latent heat
flux, and sensible heat flux are so large, negative or positive, that they
cannot be mistaken as being correct. 

The EBBR unit was replaced with a recalibrated system on 1 April 1999.
The previous unit experienced soil moisture problems the entire time
(almost 3 years) that the system was installed because of the inadequacy
of the soil moisture sensor calibrations.
