Subject: | TMP/KASACR/M1 - Reprocessed and Corrected:Mean Doppler Velocity sign reversed |
DataStreams: | tmpkasacrcwrhiM1.a1, tmpkasacrblrhiM1.a1, tmpkasacrhsrhiM1.a1, tmpkasacrppiM1.a1, tmpkasacrvptM1.a1, tmpkasacrcrcalM1.a1, tmpkasacrawrhiM1.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 earlier files have their signs reversed, so that motion TOWARD the radar has a positive sign. The mean_doppler_velocity field was multiplied by -1 to correct this, and now velocity data indicates motion away from the radar. The data was were archived March 2017. Please retrieve the modified 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::tmp/ffac::tmp.M1 ORIGINAL DQR CATEGORY: Yellow( Suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2017-03 REPROCESS IDENTIFICATION NUMBER: RID 1047 --------------------------------------------------- --- 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.
