SGP/SWATS/E15 - Incorrect soil moisture
DataStreams:sgpswatsE15.b1
Description:
At 20:00 GMT on 05/07/08, temperature rise data from ALL sensors on both profiles began 
reporting values of temperature change near 0 C. These incorrect values of temperature rise 
result in incorrect soil moisture data for all sensors. 

Soil temperature data are unaffected.

  • Soil Water Potential, West Profile(soilwatpot_W)
  • Soil Water Potential, East Profile(soilwatpot_E)
  • Volumetric Water Content, East Profile(watcont_E)
  • Sensor Temperature Rise, East Profile(trise_E)

SGP/SWATS/E15 - Noisy East 25cm sensor data
DataStreams:sgpswatsE15.b1
Description:
The trise variable for the East 25cm sensor was sporadic beginning July 14. The values 
were spiking upward (dry) especially during rain events. 

After re-seating the wires the values returned to normal, less noisy with no spikes during 
rain events.

  • Soil water potential, east profile(soilwatpot_e)
  • Reference sensor temperature rise, east profile(trise_ref_e)

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpswatsE15.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.
