DataStreams:sgp30smosE13.a1, sgp30smosE13.b1, sgp1440smosE13.a1

SGP EBBR E13 - E13 EBBR Left Air Temperature Incorrect
DataStreams:sgp5ebbrE13.a1, sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1
Description:
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.

SGP/EBBR/E13 - Reprocess: E13 EBBR Soil Temperature #4 Incorrect
DataStreams:sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1
Description:
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/THWAPS/C1 - THWAPS C1 miscalibrated
DataStreams:sgpthwapsC1.a1, sgpthwapsC1.b1
Description:
Power outages apparently led to the THWAPS HMP233 temperature and RH sensor
being replaced at C1.  The power went out at 0340 on 3/9 was restored at
0635 and went out again at 2025.

The new HMP233 appears to be incorrectly calibrated and all temperature
data since its installation are wrong.  If I am correct about the nature
of the calibration problem, the true average temperature can be recovered
from that recorded by a linear conversion, but I don't think its worth the
trouble.

The automatic exchange mechanism hung numerous times, but with various different

thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the

measurements were incorrect because the program keys off of the home signals, which must be

SGP/SMOS/E13 - Sensor failure
DataStreams:sgp1smosE13.a1, sgp1smosE13.b1, sgp30smosE13.a1, sgp30smosE13.b1, sgp1440smosE13.a1
Description:
Beginning around 1415 UTC on 08/30, the RH readings for
this instrument were frequently around 0 (sometimes
there are erratic spikes upward from 0 for periods of
time). Rainfall appears to have been the cause of the
erroneous readings, as the instrument appeared to fail
in and around the time of heavy rains.

A maintenance visit occurred on 09/04, afterwards data
returned to normal values.

SGP/EBBR/E13 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE13.b1
Description:
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).
Measurements:sgp30ebbrE13.b1:
  • average surface soil heat flow at the surface(ave_shf)
  • latent heat flux(e)
  • corrected sensible heat flux(h)

SGP/EBBR/E13 - metadata corrections
DataStreams:sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.b1
Description:
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/VCEIL/C1 - low amplitude
DataStreams:sgpvceil25kC1.b1
Description:
When the instrument was replaced with a spare, the backscatter plots began displaying a 
suspiciously low amount of amplitude (noise) but the cloud base heights were not affected. 

Discovered that when the vendor repaired this unit in August 2004, noise compensation was 
set to "OFF". Changed the parameters to "ON".

Also noted that the measurement units was set to "FEET".  This was changed to "METERS.  
The heights are not affected because the ingest recognizes the raw data units and 
automatically converts to meters.
Measurements:sgpvceil25kC1.b1:
  • Aerosol volume backscattering coefficient at 355 nm(backscatter)

least to a high value, causing the sensible and latent heat fluxes to be incorrect.
Measurements:sgp15ebbrE13.b1:
  • Atmospheric pressure(mv_pres)

  • pressure at constant pressure surface(pres)
