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 |
Measurements: | sgp15ebbrE8.b1: - Soil moisture 2 (resistance)(soil_moisture_2_r)
- Soil moisture 1 (resistance)(soil_moisture_1_r)
- Soil temperature 2 (resistance ratio)(soil_temp_2_rr)
- Soil temperature 1 (resistance ratio)(soil_temp_1_rr)
