SACRADV-QVP-C0

SACR-ADV-QVP provides a quasi-vertical representation of azimuthally-averaged polarimetric variables. These profiles may be useful to reveal important signatures in ice and mixed-phase clouds. The SACR-ADV-QVP is produced using a sequence of plan-position-indicator (PPI) scans, which typically covers 3 different elevation angles and is repeated every 30 minutes. The scientific basis and description of the algorithm is described by Ryzhkov et al. (2016). The primary inputs for the current quick-look form of this VAP are those from the uncalibrated SACR reflectivity factor and differential reflectivity fields, whereas spectrum width, differential phase, linear depolarization ratio, and correlation coefficient fields are not biased by radar miscalibration. Processing includes a light filtering procedure using polarimetric measureands to mitigate the most pronounced contamination from ground clutter and insects. This VAP outputs a daily NetCDF file containing quasi-vertical profiles of all aforementioned polarimetric variables every time the PPI scan strategy is performed (this could result an irregular time stamp).
