SGP/Sonde/C1 - Failed Sonde Launches due to Antenna problems
DataStreams:sgplssondeC1.c1, sgpsondeC1.00, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1

with the antenna configuration resulting in signal loss
before the launch.

  • base time(base_time)
  • Relative humidity inside the instrument enclosure(rh)
  • Ascent Rate(asc)
  • U-component(u_wind)
  • Wind Status(wstat)
  • Wind Direction(deg)
  • Surface dew point temperature(dp)
  • Dry bulb temperature(tdry)
  • Time offset of tweaks from base_time(time_offset)
  • lat(lat)
  • lon(lon)
  • Retrieved pressure profile(pres)

SGP/SONDE/C1 - Temperature/RH incorrect
DataStreams:sgplssondeC1.c1, sgpsondewnpnC1.b1
Description:
The temperature throughout this sounding is too high and as a result the RH values will be 
incorrect as well.  I'm not sure what is wrong here but the operators noted reasonable 
values (18.1 degC, 87%) in the log before launch.  Review of the raw data, however, shows 
the sonde reporting temperatures nearly 20 degC higher.  I suppose it is possible that 
the operator entered into the log the reference temperature from the GC25 ground check set 
rather than the temperature reported by the sonde - I can't think of any other 
explanation - there is no doubt that the temperature sensor on this sonde was bad.
Measurements:sgpsondewnpnC1.b1:
  • Surface dew point temperature(dp)
  • Dry bulb temperature(tdry)
  • Relative humidity inside the instrument enclosure(rh)
