Mobile UIUC Soundings IMPACTS V1

The Mobile UIUC Soundings IMPACTS dataset consists of atmospheric sounding data collected by rawinsondes launched during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. These data include vertical profiles of atmospheric temperature, relative humidity, pressure, wind speed, and wind direction. Specifically, these rawinsondes were provided by the University of Illinois at Urbana-Champaign (UIUC). IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic Coast. 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 sounding data files are available in netCDF-4 format from January 18 through February 25, 2022, though it should be noted that this dataset will be updated in subsequent years of the IMPACTS campaign.

该移动UIUC声学探测数据集（Mobile UIUC Soundings IMPACTS dataset）汇聚了在针对大西洋沿岸威胁性暴风雪的微物理和降水调查（IMPACTS）现场活动期间，由无线电探空仪收集的大气探测数据。这些数据涵盖了大气温度、相对湿度、气压、风速及风向的垂直剖面。特别是，这些无线电探空仪由伊利诺伊大学香槟分校（University of Illinois at Urbana-Champaign，简称UIUC）提供。IMPACTS项目是一系列为期三年的冬季部署活动，旨在研究美国大西洋沿岸的暴风雪。该活动旨在：（1）提供对理解雪带形成、组织及演化的机制至关重要的观测数据；（2）考察雪粒的微物理特征及其增长机制在雪带中的变化；（3）改进降雪的遥感解释和建模，以显著提升预测能力。探测数据文件以netCDF-4格式提供，时间范围从2022年1月18日至2月25日，尽管需要注意的是，该数据集将在IMPACTS活动的后续年份中更新。
