GRW/SONDE/M1 - Wind data missing
DataStreams:grwsondewnpnM1.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 no data was collected.  A workaround was 
developed to allow sondes to be launched without collecting wind data.
Measurements:grwsondewnpnM1.b1:
  • Wind speed, W-to-E component, at altitude, 915 MHz RWP(u_wind)
  • Wind speed, S-to-N component, at altitude, derived from ETA model(v_wind)
  • wstat
  • Wind speed, surface, 1-min avg(wspd)

longitude is -28.03.  These files have +28.03.  

The data will need to be reprocess at the DMF by correcting the beginning longitude in the 
*.parsed files and re-ingesting.
