Subject:
GAN/KASACR/S1 - Reprocessed and Corrected: Mean Doppler Velocity sign reversed
DataStreams:gankasacrppiS1.a1
Description:
DATA REPROCESSED and CORRECTED: 

The signs of the mean_doppler_velocity field values were incorrect. The ARM convention for 
this field is that positive velocities indicate motion away from the radar. However, the 
velocity data in these files had their signs reversed, so that motion TOWARD the radar 
had a positive sign.

The output data files were modified and corrected in April 2017. Please retrieve the 
corrected data for use in your analysis.
