NSA/KASACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:nsakasacrawrhiC1.b1, nsakasacrblrhiC1.b1, nsakasacrcwrhiC1.b1, nsakasacrhsrhiC1.b1,
nsakasacrppiC1.b1, nsakasacrrhiC1.b1, nsakasacrspeccmaskcopolC1.a0,
nsakasacrspeccmaskxpolC1.a0, nsakasacrvptC1.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:nsakasacrblrhiC1.b1:
  • Mean Doppler velocity, clutter filtered(mean_doppler_velocity)
