The local environment during the joint Atmospheric Radiation Measurement Program (ARM) Madden-Julian oscillation (MJO) Investigation Experiment (AMIE)-Cooperative Indian Ocean Experiment on Intraseasonal Variability in Year 2011 (CINDY2011)-Dynamics of the MJO (DYNAMO) field experiments caused frequent occurrences of sidelobe artifacts in the NCAR S-Pol radar dataset. Although generally low in radar reflectivity factor value (less than 5 dBZ), this contamination still proved problematic for Bragg scattering layer (BSL) analysis, generating numerous false BSL edge detections. In this paper, a statistical filtering technique is developed that effectively removes these false BSL edge detections, utilizing a new version of BSL analysis based on range-height indicator (RHI) data instead of plan position indicator data.
