Subject:
SGP/XSAPR/I6 - Azimuthal Drift
DataStreams:sgpxsaprhsrhiI6.00
Description:
The azimuth and elevation position were drifting over time.  The position reported in the 
files for the radar is not accurate and has an offset in azimuth at times.  There are 
periods in the data where the offset is constantly changing from scan to scan.
Measurements:sgpxsaprhsrhiI6.00:
  • Mean Doppler Velocity(mean_doppler_velocity)
  • Reflectivity(reflectivity)
  • Differential propagation phase shift(dp_phase_shift)
  • Attenuation corrected reflectivity(reflectivity_corr)
  • Lag-0 co-polar correlation coefficient, clutter filtered(copol_coeff)
  • Differential reflectivity, clutter filtered(diff_reflectivity)
  • Doppler spectral width, clutter filtered(doppler_spectral_width)
  • Unfiltered reflectivity(reflectivity_unf)
  • Signal quality index(sig_qual_index)
  • Specific differential phase, clutter filtered(diff_phase)
  • Attenuation corrected differential reflectivity(diff_reflectivity_corr)
