SBU Parsivel IMPACTS

The SBU Parsivel IMPACTS dataset consists of precipitation data collected by the Parsivel disdrometer in support of the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S. Atlantic Coast (2020-2023). The campaign aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The Parsivel disdrometer data include particle size distribution, fall speed, radar reflectivity, and precipitation rate. The dataset files are available in netCDF-3 format from January 1, 2020, through March 2, 2023.

SBU Parsivel IMPACTS 数据集由 Parsivel 雨滴谱仪收集的降水数据构成，旨在支持对大西洋沿岸暴风雪（IMPACTS）微物理和降水研究的野外考察。IMPACTS 项目为一项为期三年的冬季部署序列，旨在研究美国大西洋沿岸的暴风雪（2020-2023年）。该考察旨在（1）提供理解雪带形成、组织及演化的关键观测数据；（2）探究雪粒微物理特性和可能的增长机制在雪带间的变化；（3）提升降雪遥感解析和模型构建，以显著推进预测能力。Parsivel 雨滴谱仪数据包括粒子尺寸分布、沉降速度、雷达反射率和降水率。数据集文件以 netCDF-3 格式提供，时间跨度从 2020 年 1 月 1 日至 2023 年 3 月 2 日。
