Instrument : C-Band ARM Precipitation Radar (CSAPR)
The C-SAPR is a C-band dual-polarization Doppler weather radar manufactured by ARC, Inc. The C-SAPR operates in a simultaneous transmit and receive (STAR) mode, meaning that the transmit signal is split so that power is transmitted on both horizontal and vertical polarizations at the same time. The C-SAPR also has the ability to transmit on a single polarization (either horizontal or vertical) and measure linear depolarization ratio (LDR). The C-SAPR transmitter is a 250 kW (peak power) magnetron. The receiver is based upon the NCAR Hi-Q digital receiver and runs NCAR’s TITAN software. In addition to the first three Doppler moments (reflectivity, radial velocity, and spectra width), the C-SAPR also provides differential reflectivity, correlation coefficient, and specific differential phase. The dual-polarization variables will allow the provision to provide estimates of rainfall rates and identification of precipitation types.
The C-SAPR represents a new measurement capability for ARM.
