SGP/EEBR/E2 - AEM Stopped In One Position

The AEM kept stopping in one of three positions, none of which allow
sensible heat flux, latent heat flux, or Bown ratio to be calculated
correctly.  These and the gradient measurements are incorrect for the
period indicated.

The AEM stopped in either the home15 position (home signal about 53),
the home 30 position (home signal about 23), or inbetween these two
(home signal 1 to 2).

SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect

Soil Temperature #2 was intermittently incorrect.
The cause is unknown.

The indicated measurements that are calculated using 
soil temperature are also incorrect.

Soil moisture #2 (30 minute only) was also affected 
because version 6 of the EBBR datalogger program 
uses a multiplication of soil temperature and soil 
moisture as part of the adjustment of soil moisture for
soil temperature.  This was discovered to be a poor 
technique soon after it was implemented, but E2 will
continue to use version 6 until a replacement EBBR
unit is available.  When soil temperature #2 is large
negative, soil moisture #2 is often twice as large
as it should be.

EBBR unit changeout dates are listed on the EBBR 
instrument web page.

SGP/EBBR/E13 - Reprocess: E13 EBBR Soil heat Flows #1 and #2 Incorrect

Soil Heat Flow probes #1 and #2 were incorrect during the
indicated period (and for some time afterward, to be covered in another
DQR).  Outputs from the probes were typically too large negative or 
too large positive.

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

The left T/RH Probe Temperature was often incorrect, causing the other indicated
measurements to be incorrect also.  

When the home30 signal had an offset, the top RH probe temperature was incorrect
but not the bottom RH probe temperature.

SGP EBBR E13 - E13 EBBR AEM Home 30 Offset

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,
and the Bowen ratio are incorrect during this condition.

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/E26 - Multiplexer 2 Failure From High Temperature

Multiplexer 2 is failing during times of control box temperatures above 29 degrees C.  The 
failure begins in the last channel and progresses to lower channels as the temperature 
increases.  It has not yet been determined whether the failure is in the relays or a solid 
state component of the multiplexer.  This condition is probably due to the aging of the 
device and the millions of cycles that this 10 year old device has made.  More failures 
of this sort may occur in the future.  A cure is being sought aside from replacement of 
the multiplexers to prevent the problem.

The indicated measurements need to be inspected to determine which ones are usable.

SGP/EBBR/E7 - Wind speed incorrect

A wind speed sensor electronics problem limited the
measurement to the sensor offset.  This data was incorrect.

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

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

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

SGP/EBBR/E8 - AEM Frozen

When the AEM (Automatic Exchange Mechanism) is hung 
inbetween a home position, the gradients of temperature and 
relative humidity, and thus sensible and latent heat fluxes, 
are incorrect.

SGP/EBBR/E8 - Wind Speed Frozen

The wind speed sensor was frozen stopped by ice.  The wind speed and residual
wind speed measurements are incorrect.

SGP/EBBR/E7 - T/RH Ventilator Fans Stopped

The temperature and relative humidity gradients are suspect because the 
ventilator fans were not operating during this time period. The data needs
to be carefully inspected to determine when measurements, if any, are correct.

SGP/EBBR/E8 - Battery Voltage Low

When Battery Voltage drops below 10.5 volts, most measurements are
suspect and some are often incorrect.  The user will need to inspect the
data carefully to determine the usability of the data.
