Description: | Both trise and tsoil for the 5cm E sensor began to drop out intermittently reporting both
incorrect values and values of -9999 starting on 08/18/2007. Since this date, there have
been periods where values of -9999 have been reported continuously for months at a time,
but the sensor always seems to come back eventually and report values that appear
correct.
Currently, this sensor is reporting normal values again but has failed as recently as
10/08/08. When this sensor is failing, it typically impacts tsoil_E, trise_E, soilwatpot_E,
and watcont_E. However, there are cases where tsoil_E appears OK while the other
variables are incorrect.
