Subject:
SGP/SWATS/E11 - Incorrect soil moisture, 60cm E
DataStreams:sgpswatsE11.b1
Description:
All trise values from the 60 cm E sensor are incorrectly reporting near zero. This also 
causes the matric potential (soilwatpot_E) and water content (watcont_E) data to be 
incorrect at this depth.

SGP/SWATS/E11 - 35 cm E sensor Inconsistent with 35 cm W
DataStreams:sgpswatsE11.b1
Description:
The 35 cm E sensor seems to report incongruent temperature rise, fractional water index, 
and soil water potential values.
Measurements:sgpswatsE11.b1:
  • Reference sensor temperature rise, east profile(trise_ref_e)
  • Volumetric water content, east profile(watcont_e)
  • fwi_e
  • Soil water potential, east profile(soilwatpot_e)

SGP/SWATS/E11 - Depth 125 and 175 Soil Measurements Suspect
DataStreams:sgpswatsE11.b1
Description:
Depth 125 and 175 east and west trise values have exceeded their maximum limits, probably 
the result of incorrect calibration of the sensors. This problem will not be resolved 
until the SWATS system is replaced by a new system.
Measurements:sgpswatsE11.b1:
  • Sensor temperature rise, east profile(trise_e)
  • Sensor temperature rise, west profile(trise_w)
  • Volumetric water content, east profile(watcont_e)
  • fwi_e

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpswatsE11.b1
Description:
On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought 
sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result 
was very very slick roads and mass power outages.
 
The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th.  
The power was restored on 7:56 PM CDT on Wednesday, December 30th
 
Site Emergency procedures were activated and Technicians drained water out of instrument 
reservoirs and other measures as needed, early Monday morning.
 
On Wednesdays as roads and power started was restored to much of the areas east of I-35 , 
Site Technicians performed maintenance on several Extended Facilities.

During this period, data are potentially missing, incorrect, or suspect.  Carefully 
inspect the data before use.
