Key Technologies of Hydrometeor Classification and Mosaic Algorithm for X-band Polarimetric Radar
应用气象学报, 2021 The advantages of X-band polarimetric weather radar focus on its high spatio-temporal resolution and capability of multi-radar networking. However, the previously designed hydrometeor classification algorithm (HCA) for S-band weather radar is unsuitable ...

Unraveling hydrometeor mixtures in polarimetric radar measurements [PDF]
Atmospheric Measurement Techniques, 2018 Radar-based hydrometeor classification typically comes down to determining the dominant type of hydrometeor populating a given radar sampling volume. In this paper we address the subsequent problem of inferring the secondary hydrometeor types present ...

Solid hydrometeor classification and riming degree estimation from pictures collected with a Multi-Angle Snowflake Camera [PDF]
Atmospheric Measurement Techniques, 2017 A new method to automatically classify solid hydrometeors based on Multi-Angle Snowflake Camera (MASC) images is presented. For each individual image, the method relies on the calculation of a set of geometric and texture-based descriptors to ...

Polarimetric signatures and hydrometeor classification of West African squall lines
Quarterly Journal of the Royal Meteorological Society, 2010 AbstractDuring the AMMA campaign, the Doppler and polarimetric radar Ronsard was deployed in Kopargo, Benin. In the present paper, three squall lines sampled during that period are described. It was the first time this type of system had been observed with a polarimetric radar in the West African region. The strongest case occurred on 28 July 2006, and

Hydrometeor Identification Using Multiple-Frequency Microwave Links: A Numerical Simulation
Remote Sensing, 2020 A method for identifying hydrometeor types (rain, graupel, and wet snow) based on a microwave link is proposed in this paper. The measured hydrometeor size distribution (HSD) data from the winters of 2014 to 2019 in Nanjing, China, were used to carry out

Objective classification for solid hydrometeor particles using deep learning
Progress in Earth and Planetary ScienceVarious small particles are present in the clouds. Hydrometeor videosonde (HYVIS) is an in situ instrument to observe such particles. The movies were used to capture hydrometeors with approximately 110,000 frames per sounding.

Journal of Applied Meteorology and Climatology, 2000 Abstract A new synthesis of information forming the foundation for rule-based systems to deduce dominant bulk hydrometeor types and amounts using polarimetric radar data is presented. The information is valid for a 10-cm wavelength and consists of relations that are based on an extensive list of previous and recent observational and modeling studies of

Development of a polarimetric radar based hydrometeor classification algorithm for winter precipitation [PDF]
, 2012 The nation-wide WSR-88D radar network is currently being upgraded for dual-polarized technology. While many convective, warm-season fuzzy-logic hydrometeor classification algorithms based on this new suite of radar variables and temperature have been refined, less progress has been made thus far in developing hydrometeor classification algorithms for ...

Error Evaluation and Hydrometeor Classification Method of Dual Polarization Phased Array Radar
应用气象学报, 2022 Phased array radar is faster in scanning speed than mechanical scanning radar, but due to the influence of antenna structure and attenuation, phased array radar will produce larger system error and random error.
