SGP/KASACR/C1 - Mean Doppler Velocity sign reversed

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.

SGP/KAZR/C1 - Incorrect metadata radar parameters

Description:
Metadata in these files are wrong.  Antenna gain, beamwidth, system losses, etc. were not 
set in the correct file when the KAZR was originally installed.  However, these values 
are not used to calculate the radar constant so reflectivity values are still correct.  

The correct values for the SGP KAZR are:

tx_path_loss_db=0.91
  dielectric_factor=0.94
  h_gain_db=57.48
  h_beamwidth_theta_deg=.19
  h_beamwidth_phi_deg=.19
  v_gain_db=57.48
  v_beamwidth_theta_deg=.19
  v_beamwidth_phi_deg=.19
  probert_jones_correction_db=0.0
  radome_loss_twoway_db=2
  rx_path_loss_db_copol=2.20
  rx_path_loss_db_xpol=1.77
  finite_bandwidth_loss_db_ch1=1.5
  finite_bandwidth_loss_db_ch2=1.5
