GAN/XSACR/S1 - Reprocessed and Corrected: Mean Doppler Velocity sign reversed
DataStreams:ganxsacrppiS1.a1, ganxsacrrhiS1.a1, ganxsacrblrhiS1.a1, ganxsacrcwrhiS1.a1
Description:
DATA REPROCESSED and CORRECTED: 

Multiplied the mean_doppler_velocity values by -1. This will result in motion away from 
the radar having a positive sign.

The data were reprocessed in December 2016. Please retrieve the reprocessed data for use 
in your analysis.

You may find these data using the ARM Discovery tool at the following link:

ORIGINAL DQR CATEGORY: Yellow (Suspect)

REPROCESSED and CORRECTED DATA ARCHIVED:2016-12

REPROCESS IDENTIFICATION NUMBER: RID 844

---------------------------------------------------
--- ORIGINAL DQR 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.
