S-Pol Radar Request Guidance

NCAR's S-band, polarimetric (S-Pol) radar combines dual-polarization and Doppler measurements on a single radar platform. It is capable of discriminating and classifying various types of precipitation (e.g., rain, hail, ice crystals, graupel, etc.). S-Pol also quantifies low level moisture content (via ground clutter targets) as well as rain rainfall rates. S-Pol can be disassembled, packed into seven sea containers, transported and deployed to anywhere in the world and is remotely operable. It is one of two dual polarimetric, transportable, high data quality S-band  weather 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
