Water Isotope System for Precipitation and Entrainment Research (WISPER) IMPACTS

The Water Isotope System for Precipitation and Entrainment Research (WISPER) IMPACTS dataset consists of condensed water contents, water vapor measurements, and isotope ratios 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 dataset files are available in ASCII format from January 18, 2020, through February 28, 2023.

WISPER（降水与捕集研究水同位素系统）IMPACTS数据集，包含了凝结水含量、水汽测量值以及支持大西洋沿岸威胁性暴风雪微物理与降水调查（IMPACTS）野外考察的稳定同位素比率。IMPACTS是一项为期三年的冬季季节部署序列，旨在研究美国大西洋沿岸的暴风雪（2020-2023年）。该考察旨在：（1）提供对理解雪带形成、组织与演化的关键观测；（2）探究雪粒子微物理特征及其可能的增长机制在雪带间的变化；（3）提高降雪遥感解释和模型构建，以显著提升预测能力。数据集文件自2020年1月18日至2023年2月28日以ASCII格式提供。
