Subject:
SGP/EBBR/E8 - Incorrect Soil Temperature #s 1 and 2
DataStreams:sgp30ebbrE8.b1, sgp15ebbrE8.b1
Description:
Soil temperature probes #1 and #2 were replaced on June 10, 1997.  However, 
the leads were apparently not connected tightly enough, resulting in 
some large or offscale resistance measurements and therefore temperature 
values for those probes.  The problem occurred only occasionally until June 
20, 1997.  On June 20 - 24, 1997 probes 1 and 2 outputs were offscale for 
several hours per day, both not always at the same time.  On June 24, 1997, 
site operations checked and tightened the connections.  No offscale values 
have occurred since then.

Affected data values were:

15 minute: r_sm1, r_sm2, rr_ts1, rr_ts2

30 minute: sm1, sm2, ts1, ts2, c_shf1, c_shf2, ces1, ces2, 
cs1, cs2, g1, g2, ave_shf, e, h
Suggestions: 
Do not use identified variables during the period when the 
probes are offscale.
