NSA/WSACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:nsawsacrawrhiC1.b1, nsawsacrblrhiC1.b1, nsawsacrcwrhiC1.b1, nsawsacrhsrhiC1.b1,
nsawsacrppiC1.b1, nsawsacrrhiC1.b1, nsawsacrspeccmaskcopolC1.a0, nsawsacrspeccmaskxpolC1.a0,
nsawsacrvptC1.b1
Description:
The signs of the mean_doppler_velocity field values are incorrect.  The ARM convention for 
this field is that positive velocities indicate motion away from the radar.  However, 
the velocity data in these files have their signs reversed, so that motion TOWARD the radar 
has a positive sign.
Measurements:nsawsacrcwrhiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrppiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrrhiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrblrhiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrspeccmaskcopolC1.a0:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrspeccmaskxpolC1.a0:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrhsrhiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
nsawsacrvptC1.b1:

NSA/WSACR/C1 - Azimuth Offset
DataStreams:nsawsacrawrhiC1.b1, nsawsacrblrhiC1.b1, nsawsacrcwrhiC1.b1, nsawsacrhsrhiC1.b1,
nsawsacrppiC1.b1, nsawsacrrhiC1.b1
Description:
When comparing against the XSAPR, there is a noticeable 180 degree offset in the returns.  
This stems from problems with the pedestal.
