Title: Pre-CIP_2021: CSU-CHILL Radar Data. Version 1.0
Data from the Colorado State University (CSU) CHILL radar located near Greeley, Colorado during the Pre-CIP_2021 (Preparatory Rockies Experiment for the Campaign In the Pacific 2021) campaign in July and August 2021. CHILL is a dual wavelength S- and X-band, dual-polarization radar that conducted RHI and surveillance scans.  more » « less

    Abstract The Precipitation Occurrence Sensor System (POSS) is a small X-band Doppler radar that measures the Doppler velocity spectra from precipitation falling in a small volume near the sensor. The sensor records a 2D frequency of occurrence matrix of the velocity and power at the mode of each spectrum measured over 1 min. The centroid of the distribution of these modes, along with other spectral parameters, defines a data vector input to a multiple discriminant analysis (MDA) for classification of the precipitation type. This requires the a priori determination of a training set for different types, particle size distributions (PSDs), and wind speed conditions. A software model combines POSS system parameters, a particle scattering cross section, and terminal velocity models, to simulate the real-time Doppler signal measured by the system for different PSDs and wind speeds. This is processed in the same manner as the system hardware to produce bootstrap samples of the modal centroid distributions for the MDA training set. MDA results are compared to images from the Multi-Angle Snowflake Camera (MASC) at the MASCRAD site near Easton, Colorado, and to the CSU–CHILL X-band radar observations from Greeley, Colorado. In the four case studies presented, POSS successfully identified precipitation transitions through a range of types (rain, graupel, rimed dendrites, aggregates, unrimed dendrites). Also two separate events of hail were reported and confirmed by the images.

    Data from the Parsivel disdrometer that was deployed on Yonaguni (a Japanese island to the east of Taiwan) for the PRECIP (Prediction of Rainfall Extremes Campaign in the Pacific) campaign from June to August 2022. It was deployed near the CSU SEA-POL dual-polarization radar to obtain drop-size distribution measurements in Mei-yu fronts, thunderstorms, and tropical cyclones.
