Subject: | TMP/XSACR/M1 - Reprocessed and Corrected: Mean Doppler Velocity sign reversed |
DataStreams: | tmpxsacrvptM1.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 mean_doppler_velocity values were multiplied by -1, so now motion away from the radar has a positive sign. The data 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::xsacr/fsite::tmp/ffac::tmp.M1 ORIGINAL DQR CATEGORY: Yellow( Suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2017-03 REPROCESS IDENTIFICATION NUMBER: RID 1046 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The signs of the mean_doppler_velocity field values are incorrect.

Subject: | TMP/MWACR/M1 - Instrument failure |
DataStreams: | tmpmwacrM1.a1 |
Description: | During this period, there were gaps in the data due to restarts and subsequent computer hangups. During this period, the radar clutter filter was not turned on causing a noisy signal when there were no significant radar returns. |

Description: | See below for details of reprocessing that was completed on 20150706. Original DQR category: 5 (Transparent - Does not affect quality). ----------------------------------------------------------- The field 'linear_depolarization_ratio' is misnamed. The field should instead be called 'differential_reflectivity,' |

Subject: | TMP/XSACR/M1 - Incorrect calibration constant recorded |
DataStreams: | tmpxsacrvptM1.a1 |
Description: | Files contain incorrect values for calibration constant(s). All other fields are correct, including reflectivities. For moments files, the affected fields are called 'r_calib_radar_constant_h' and 'r_calib_radar_constant_v.' In spectra files, the global attribute 'cal_constant' is incorrect. |

Subject: | TMP/MWACR/M1 - Possible antenna offset from zenith |
DataStreams: | tmpmwacrM1.a1 |
Description: | A preliminary analysis of vertically-pointing Doppler velocity from all four radars at the site (KAZR, MWACR, KaSACR and XSACR) suggests that MWACR may have a systematic velocity bias. The bias appears to depend on height and wind profile, suggesting it could be caused by mispointing of the MWACR. A more detailed study of the radars plus sounding information indicates the MWACR is mispointed by approximately 1 degree from zenith, into azimuth direction of 75 degrees from North. |
