NCAR S-Pol Radar Request Guidance Information

The NCAR S-band/Ka-band, polarimetric (S-PolKa) radar combines dual-polarization, dual-wavelength (S-band and Ka-band) and Doppler measurements on a single radar platform. The S- and Ka-band radars take simultaneous, collocated dual-polarimetric measurements making S-PolKa the only transportable radar in the world that is capable of describing air motions, boundary layer humidity, cloud initiation and precipitation microphysics.

Configuration: Ground-based; transportable, fixed
Number of available systems: 1
