Layers of enhanced spectrum width within Northeast United States coastal winter storms

This dataset was produced in support of Leghart et al. 2025 (in review, Monthly Weather Review), which investigates shear and turbulence within winter storms by identifying and characterizing spectrum width layers (SWLs)—coherent horizontal features associated with turbulent or shear-driven processes in the cloud. This dataset contains Ka-band radar observations collected by the Ka-Band Scanning Polarimetric Radar (KASPR), located at Stony Brook University (40.899°N, 73.127°W) on Long Island, NY, during cool-season precipitation events between 2017 and 2021. KASPR is a dual-polarization, Doppler radar designed to observe fine-scale cloud and precipitation structures with high spatial and temporal resolution. Technical details and performance characteristics of the radar are described in Kumjian et al. (2020, J. Appl. Meteor. Climatol., https://doi.org/10.1175/JAMC-D-20-0054.1) and Kollias et al.

本数据集为支持Leghart等人2025年的研究（已投稿至《月度气象评论》并处于审稿阶段）而构建，该研究通过识别并表征谱宽层（Spectrum Width Layers，SWLs）——即云层中与湍流或切变驱动过程相关的连贯水平特征——来探究冬季风暴中的切变与湍流现象。本数据集包含由位于纽约州长岛石溪大学（坐标40.899°N，73.127°W）的Ka波段扫描偏振雷达（Ka-Band Scanning Polarimetric Radar，KASPR）在2017至2021年冷季降水事件期间采集的Ka波段雷达观测数据。KASPR是一部双偏振多普勒雷达，旨在以高时空分辨率观测精细尺度的云和降水结构。该雷达的技术细节与性能特征详见Kumjian等人2020年发表于《应用气象与气候学杂志》的研究（https://doi.org/10.1175/JAMC-D-20-0054.1）以及Kollias等人2020年发表于《地球物理研究通讯》的研究（https://doi.org/10.1029/2020GL088440）。KASPR为……之一，，# 美国东北部沿海冬季风暴中的增强谱宽层
