SGP/SONDE/C1 - Wind, lat/lon data missing
DataStreams:sgpsondewnpnC1.b1
Description:
It appears the GPS-derived data (wind speed, wind direction, lat, lon) is missing due to a 
failure of the GPS components on the radiosonde.  Data is missing and not recoverable.

  • wstat
  • East longitude(lon)
  • Wind speed, surface, 1-min avg(wspd)
  • Wind direction, at altitude(deg)
  • Wind speed, S-to-N component, at altitude, derived from ETA model(v_wind)
  • North latitude(lat)
  • Wind speed, W-to-E component, at altitude(u_wind)

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpsondewnpnC1.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.
Measurements:sgpsondewnpnC1.b1:
  • Temperature, dewpoint, at altitude(dp)
  • Dry Bulb Temperature(tdry)
  • East longitude(lon)
  • Wind speed, surface, 1-min avg(wspd)
  • base_time
  • asc
  • Pressure, atmospheric, constant value of model level, RUC model output(pres)
  • Wind direction, at altitude(deg)
  • Wind speed, S-to-N component, at altitude, derived from ETA model(v_wind)
  • North latitude(lat)
  • time_offset
  • Altitude above mean sea level(alt)
  • wstat
  • Humidity, relative, on hybrid-b grid, derived from RUC model(rh)
  • Wind speed, W-to-E component, at altitude(u_wind)
