SGP/SWATS/E13 - Reprocessing Notice (RID 156)
DataStreams:sgpswatsE13.b1
Description:
See below for details of reprocessing that was completed on 20150814.  Original DQR 
category: 5 (Transparent - Does not affect quality).

-----------------------------------------------------------

The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.
Measurements:sgpswatsE13.b1:

SGP/SWATS/E13 - Lightning damage
DataStreams:sgpswatsE13.b1
Description:
After a lightning strike near the CF, the SWATS trise values were reporting near zero. The 
current channel in the CE8 module failed, so the wire was moved to the next channel and 
trise values returned to normal.

There are no soil moisture data available during this time period.

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

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpswatsE13.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.
