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.
