| Subject: | GAN/KASACR/S1 - Reprocessed and Corrected: Mean Doppler Velocity sign reversed |
| DataStreams: | gankasacrvptS1.a1, gankasacrcwrhiS1.a1, gankasacrrhiS1.a1, gankasacrppiS1.a1, gankasacrblrhiS1.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. Data were corrected by multiplying the mean_doppler_velocity values by -1. This results in motion away from the radar having a positive sign. The data were archived in March 2017. Please retrieve the reprocessed data for use in your analysis. You may find these data using the ARM Discovery tool at the following link: http://www.archive.arm.gov/discovery/#v/results/s/finst::kasacr/fsite::gan/ffac::gan.S1 ORIGINAL DQR CATEGORY: Yellow( Suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2017-03 REPROCESS IDENTIFICATION NUMBER: RID 843 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The signs of the mean_doppler_velocity field values are incorrect.
