SGP/SWATS/E10 - Soil temperature irregular, 25cm W
DataStreams:sgpswatsE10.b1
Description:
The 25 cm W sensor was demonstrating temporal irregularities and were noisy at times.  
These irregularities consisted of dips and increases of around 2-4 C that typically started 
around 14:00 or 15:00 GMT on most days. On other days the values appeared somewhat noisy 
throughout the day. In both cases, the temporal changes did not compare well with the 
other sensors installed at E10.

A broken wire was repaired for 25cm W sensor.
Measurements:sgpswatsE10.b1:
  • Soil Temperature, West Profile(tsoil_W)
