SGP/RWP/I1 - Wind speed too small, directions likely bad due to incorrect beam control
DataStreams:sgp915rwpwindconI1.a1, sgp915rwpwindmomI1.a0, sgp915rwpwindspecI1.a0
Description:
two beams, sometimes three of the four tilted possible are incorrect due either to a phase 
shifter problem or improper control of the phase shifter.
Measurements:sgp915rwpwindspecI1.a0:
  • Backscatter, doppler spectrum, 915 MHz RWP(spc_amp)
sgp915rwpwindconI1.a1:
  • Eastward Wind Component(u_wind)
  • Beam 3 radial wind speed(vel3)
  • Beam 4 radial wind speed(vel4)
  • Beam 1 radial wind speed(vel1)
  • Beam 2 radial wind speed(vel2)
  • Northward Wind Component(v_wind)

Subject:
SGP/RWP/C1 - Reprocess: Wind directions reversed
DataStreams:sgp915rwpwindconC1.a1, sgp915rwpwindmomC1.a0
Description:
The new phase shifter had the delay lines reversed, which resulted in the beams going in 
the wrong directions.  The speeds are correct and the directions are 180 deg off.  
Vertical velocities are ok
