X-Band Scanning ARM Cloud Radar PPI scan, Cartesian Cloud Cover VAP

Evaluation VAP

This Scanning ARM Cloud Radar Grid (SACRGRID) value-added product for the X-Band Scanning ARM Cloud Radar (XSACR) provides radar moments from plan position indicator (PPI) scans on a Cartesian grid. The gridded radar moments include reflectivity, mean Doppler velocity, spectral width, signal-to-noise ratio, and differential reflectivity. The moments are accompanied by the differential phase and copolar correlation coefficient.

Input data are a1-level (uncalibrated) or b1-level (calibrated) PPI data. A nearest
neighbor algorithm is used for gridding. The output is a single netCDF file with radar moments remapped onto a two-dimensional (2D) Cartesian grid.
