UAlbany Parsivel IMPACTS

The UAlbany Parsivel IMPACTS dataset consists of precipitation data collected by a Parsivel2 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-4 format from 30 January 2020 through 28 February 2023.

乌尔班纳大学帕西维尔 IMPACTS 数据集包含由 Parsivel2 气象学粒径仪收集的降水数据，旨在支持对大西洋沿岸威胁性暴风雪（IMPACTS）微物理和降水研究的野外考察。IMPACTS 是一项为期三年的冬季季节部署活动，旨在研究美国大西洋沿岸的暴风雪（2020-2023）。该活动旨在（1）提供对雪带形成、组织和发展机制理解至关重要的观测数据；（2）探讨雪粒子微物理特性及其可能增长机制在雪带间的差异；（3）提升降雪远程传感解释和模型构建，以显著推进预测能力。帕西维尔气象学粒径仪数据包括粒子尺寸分布、下降速度、雷达反射率和降水率。数据集文件以 netCDF-4 格式提供，时间范围从 2020 年 1 月 30 日至 2023 年 2 月 28 日。
