RAD-01KASPR
The flagship radar of the observatory. KASPR collects Doppler spectra and radar moments through alternate transmission of horizontally and vertically polarized waves and simultaneous reception of co-polar and cross-polar components of the backscattered wave with a beamwidth of 0.32°. A full set of polarimetric radar observables is available, enabling identification of microphysical processes.

RAD-02SKYLER-I
X-band Phased Array Radar with antenna beamwidth of 1.98° in azimuth and 2.1° in elevation at boresight. Beam is electronically scanned ±45° in horizontal and ±15° in vertical. Transmits H- and V-polarization pulses (alternating) for ΦDP, KDP, ZDR, and ρHV in addition to standard power and Doppler measurements.

RAD-03SKYLER-II
Second-generation system (2021, with Raytheon Technologies) using a single-channel transmit/receive module and a dual-polarization antenna in alternating-transmit, alternating-receive (ATAR) mode. Its software-defined transceiver uses long-duty-cycle pulses and pulse compression for sensitivity and phase coding to suppress multi-trip echoes; the Weather Data Processor delivers full polarimetric moments.

Software

Software tools.

Open-source and operational software developed by the group for radar control, forward modeling, and data analysis.

SW-01 / NSF CISE
MAAS
The Multisensor Agile Adaptive Sampling cyberinfrastructure significantly improves the ability to sample rapidly evolving atmospheric phenomena by providing real-time, fine-grained, coordinated control across multiple advanced radar systems. Transformative elements include real-time external observations for situational awareness, feature detection and tracking, and integration of future observing technologies such as drones and phased-array radars.

SW-02 / Open-source
CR-SIM
The Cloud-resolving model Radar Simulator is a forward-modeling framework that converts numerical weather prediction model output into synthetic radar observations by simulating electromagnetic scattering from model-resolved hydrometeors across multiple radar frequencies, polarizations, and viewing geometries. Accounts for hydrometeor size distributions, phase-dependent dielectric properties, attenuation, and Doppler effects.
