Subject:
SGP/EBBR/E13 - Incorrect Soil Temperature #4
DataStreams:sgp30ebbrE13.b1, sgp15ebbrE13.b1
Description:
For periods of a number of days in December 1994, soil temperature probe #4
indicated incorrect values that were either too high or too low.  Site
Operations personnel replaced the sensor on December 30, 1994.  The times
and incorrect data fields are listed below.  Only half hour times are
listed.  The incorrect data on December 30 was the result of the process of
replacing the sensor during that time.

Data Fields:
15 minute: rr_ts4
30 minute: ts4, ces4, g4, ave_shf, e, h

Recomputation of the change in energy storage in the soil could be done
roughly from the soil temperature sensors that were still working (roughly
because the difference in soil temperature with time is determined with
real-time (one minute samples) data, not from the 15 or 30 minute data).
However, this would require considerable effort.  The process for doing so
is therefore not stated here.  Contact the mentor for more information if
neccesary.
