SGP/SEBS/E21 - Soil surface heat flux and energy balance incorrect
DataStreams:sgpsebsE21.b1
Description:
A connection or multiplexer issue caused the #1 set of soil values to be incorrect, 
resulting in the surface soil heat flux and surface energy balance to be incorrect.

  • Soil temperature mean 1(soil_temp_1)
  • corr_soil_heat_flow_1
  • Surface energy balance(surface_energy_balance)

SGP/SEBS/E21 - Soil moisture 1 not buried
DataStreams:sgpsebsE21.b1
Description:
Soil Moisture 1 sometimes was too low, a result of the sensor being exposed above the 
soil.  The surface energy balance was incorrect during those periods.
Measurements:sgpsebsE21.b1:
  • corr_soil_heat_flow_1
  • Surface energy balance(surface_energy_balance)
  • soil_heat_capacity_1
  • soil_heat_flow_1

SGP/SEBS/E21 - Soil Temperature #1 Bouncing Around
DataStreams:sgpsebsE21.b1
Description:
Soil temperature #1 was somewhat exposed and didn't always trend with the other soil 
temperature sensors. Effects on the surface energy balance were minimal.
Measurements:sgpsebsE21.b1:
  • Soil temperature mean 1(soil_temp_1)
  • Surface energy balance(surface_energy_balance)
  • surface_soil_heat_flux_1
  • energy_storage_change_1

SGP/SEBS/E21 - Soil Moisture Sensor 3 Too Dry
DataStreams:sgpsebsE21.b1
Description:
At times soil moisture 3 showed too dry a soil moisture because of being exposed near the 
soil surface.

SGP/SEBS/E21 - Soil Set 3 Measurements Offscale
DataStreams:sgpsebsE21.b1
Description:
Sometimes the soil sensor measurements go offscale, most likely because of the very long 
lead lengths on the sensors or because of very dry soil conditions. This has been reported 
a number of times and the occurrence of the situation can not be predicted.

In this case soil sensor set 3 was incorrect.
Measurements:sgpsebsE21.b1:
  • soil_moisture_3
  • Soil temperature mean 3(soil_temp_3)
  • Surface energy balance(surface_energy_balance)
  • corr_soil_heat_flow_3

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpsebsE21.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.
