Kwajalein Polarimetric S-band Weather Radar (KPOL)
 |
The KPOL is a dual-polarized, simultaneous transmit and receive capable system used to detect, analyze, and record precipitating weather systems. The height, distance, intensity, and course of echo returns can be established when tracking storms and precipitation.
A Sigmet, Inc. RVP-8 Digital Signal Processor and Radar Control Processor (RCP-8) combination is used to control radar scans so that plan position indicator (PPI), range height indicator (RHI), volume, and sector scans can be performed on demand.
Meteorological products derived from KPOL scans include reflectivity, differential reflectivity (ZDR), propagation differential phase (PhiDP), specific propagation differential phase (KDP), correlation coefficient (RhoHV), rainfall rate, rainfall accumulation, radial velocity, velocity volume processing (VVP) wind fields, Doppler spectrum width, echo tops, volume integrated liquid (VIL), and other parameters.
