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 data was modified and archived in July 2017. Please retrieve the modified data for use in your analysis.

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.

--- ORIGINAL DQR SUGGESTIONS ---
---------------------------------------------------
Multipy the mean_doppler_velocity values by -1 prior to using the data. This will result in motion away from the radar having a positive sign. |
