TWP/SONDE/C2 - Wind data missing
DataStreams:twpsondewnpnC2.b1
Description:
A GPS problem associated with Vaisala BBSS ground station software issues caused the 
ground stations to enter into an error state when using GPS wind finding. In some instances, 
the flight was aborted due to the error state and not data was collected.  A workaround 
was developed to allow sondes to be launched without collecting wind data.
Measurements:twpsondewnpnC2.b1:
  • wstat
  • Eastward Wind Component(u_wind)
  • Northward Wind Component(v_wind)
  • Mean Wind Speed(wspd)
