Autonomous Parsivel Unit (APU) IMPACTS

The Autonomous Parsivel Unit (APU) IMPACTS data were collected in support of the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign. The IMPACTS field campaign addressed providing observations critical to understanding the mechanisms of snowband formation, organization, and evolution, examining how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands, and improving snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. This dataset consists of precipitation data including precipitation amount, precipitation rate, reflectivity in Rayleigh regime, liquid water content, drop diameter, and drop concentration. Data are available in ASCII format from January 15, 2020 through February 29, 2020.

自主解析单元（APU）IMPACTS数据集的收集旨在支持对大西洋沿岸暴风雪微物理和降水机制的研究（IMPACTS）项目。该研究项目旨在提供理解雪带形成、组织及演化的关键观测数据，探讨雪粒子的微物理特性及其可能的增长机制在雪带中的变化情况，并旨在提升降雪遥感解释和建模能力，以显著推进预测能力的提升。本数据集包含降水数据，包括降水量、降水速率、拉伊利波段的反射率、液态水含量、液滴直径和液滴浓度。数据以ASCII格式提供，时间范围从2020年1月15日至2020年2月29日。
