Abstract: he 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.
