Display on which radar signals are shown in plan position with range and azimuth angle displayed in polar coordinates, forming a map-like display.
The PPI is a 2D-map projection of a conical surface at predefined elevation containing either reflectivity, precipitation intensity, the radial component of wind velocity or one of the dual polarization parameters. A Polar volume consists of many PPIs. A set of PPIs for various elevations may be given inside of the same product, but they all must contain the same product data quantity.
Notes
• PPI of velocity can be used as input for dual Doppler products • For dual pol parameters other optional parameters...
