Description:
The temperature rise readings from the 25-cm depth on the east profile are incorrect. This 
also causes the matric potential and water content data to be incorrect.

SGP/SWATS/E7 - Sensor failure, 35cm E
DataStreams:sgpswatsE7.b1
Description:
The 35cm East profile data spiked out of range on 20040106. Soil temperature is incorrect 
at 0407 GMT, and all 35cm E data are incorrect at 0407 and 0507 GMT.

The 35cm East profile sensor failed on 20040127 around 1300 GMT. All data from this sensor 
are incorrect or missing until 20040208.

The 35cm East temperature rise readings were noisy and inconsistent with the rest of the 
data 20040317-20040623. This also caused the matric potential and water content data to be 
suspect.

The 35cm East soil temperature measurements were incorrect beginning 20041223 to 9:07 on 
12/24. Temperature rise, soil-water potential, and water content are incorrect from from 
the same start time to 11:07 GMT on 12/24.

SGP/SWATS/E5 - Incorrect soil moisture data
DataStreams:sgpswatsE5.b1
Description:
The temperature rise values were too high (> 20 deg C).  Water potential is calculated 
from a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees 
C.  When the T_rise is too high, the soil moisture data is dubious at best and unusable 
at worst.

Soil temperatures are OK.

SGP/SWATS/E7 - Sensor failure, 35cm E
DataStreams:sgpswatsE7.b1
Description:
The 35-cm East sensor had several problems before failing permanently in 2007:

20061208.2000-20070306.2000: temperature rise reported values of -9999, and soil 
temperature reported abnormally high temperature values.  

20070813.1200-20070912.1300: all variables reported as -9999, including soil temperature.  
A very small number of soil temperature values were reported as unusually high 
temperature values after 09/10/07.

20070912.1300-20070915.1600:  incorrect values of temperature rise reported (near 0 C), 
and soil temperature values incorrect and unusually high.

20071110.0000-20071115.2300:  incorrect values of temperature rise reported near 0 C or 
unusually low.  Values of soil temperature OK.  

20071128.0000-->:  Except for two very brief recoveries (on the order of a few days), all 
35cm E variables are reported as -9999.

DataStreams:sgpswatsE5.b1
Description:
Both the temperature rise and soil temperature for the 15-cm W profile began to 
intermittently report as -9999 on 04/08/08. The intermittent drop outs continued until 9:00 GMT on 
04/20/08 after which all data are reported as -9999 through the current date. This 
problem also impacts the matric potential and water content data.

SGP/SWATS/E7 - Soil temperature irregular, 125cm E
DataStreams:sgpswatsE7.b1
Description:
The 125 cm E sensor was demonstrating temporal irregularities in its soil temperature 
measurements.  These irregularities consisted of dips and increases of around 2-4 C that 
typically started around 14:00 or 15:00 GMT on most days. On other days the values appeared 
somewhat noisy throughout the day. In both cases, the temporal changes did not compare 
well with the other sensors installed at E7.  

A bad fiber optic cable was replaced.
