Subject:	SGP/KASACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:	sgpkasacrawrhiC1.b1, sgpkasacrblrhiC1.b1, sgpkasacrcrrhiC1.b1, sgpkasacrcwrhiC1.b1, sgpkasacrppiC1.b1, sgpkasacrrhiC1.b1, sgpkasacrslrC1.b1, sgpkasacrspeccmaskcopolC1.a0, sgpkasacrspeccmaskxpolC1.a0, sgpkasacrvptC1.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:	sgpkasacrcwrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrslrC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrspeccmaskxpolC1.a0: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrvptC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrblrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrppiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrspeccmaskcopolC1.a0: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrcrrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrawrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity) sgpkasacrrhiC1.b1: Mean Doppler velocity, clutter filtered(mean_doppler_velocity)

Subject:	SGP/KAZR/C1 - Incorrect metadata radar parameters
DataStreams:	sgpkazrC1.00, sgpkazrblC1.b1, sgpkazrciC1.b1, sgpkazrgeC1.b1, sgpkazrspeccmaskblcopolC1.a0, sgpkazrspeccmaskblxpolC1.a0, sgpkazrspeccmaskcicopolC1.a0, sgpkazrspeccmaskcixpolC1.a0, sgpkazrspeccmaskgecopolC1.a0
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
