Two-Dimensional Video Disdrometer (2DVD) IMPACTS V1

The Two-Dimensional Video Disdrometer (2DVD) 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. These data consist of the size, equivalent diameter, fall speed, oblateness, cross-sectional area of raindrops, particle concentration, total number of drops, total drop concentration, liquid water content, rain rate, reflectivity, and rain event characteristics. Data files are available from January 15, 2020 through February 28, 2020 in ASCII format.

二维视频降雪量计（2DVD）的IMPACTS数据集是为了支持对大西洋沿岸威胁性暴风雪的微物理和降水机制（IMPACTS）调查而收集的。该调查旨在提供对雪带形成、组织与演化的机制进行理解的临界观测，研究雪粒的微物理特性及其可能的增长机制在不同雪带间的变化，以及提升降雪远程传感的解读和建模能力，以显著推进预测能力。这些数据包括雨滴的大小、等效直径、下落速度、扁平度、横截面积、粒子浓度、总滴数、总滴浓度、液态水含量、雨量、反射率和雨事件特性。数据文件以ASCII格式提供，时间范围从2020年1月15日至2020年2月28日。
