Millersville University Upper Air Radiosondes IMPACTS V1

The Millersville University Upper Air Radiosondes IMPACTS dataset contains atmospheric temperature, dew point temperature, wind speed, and wind direction measurements using Vaisala’s Radiosonde RS41-SGP and Sparv Embedded S1H3 Windsond during 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 advance prediction capabilities significantly. Data are available from January 16, 2022, through February 28, 2023 in ASCII format.

米尔维尔大学高空辐射计观测数据集（IMPACTS）收录了在探究大西洋沿岸威胁性暴风雪的微物理和降水过程（IMPACTS）实地考察期间，利用Vaisala公司生产的RS41-SGP辐射计和Sparv嵌入式S1H3风向风速仪所采集的大气温度、露点温度、风速和风向测量数据。IMPACTS项目是一项为期三年的冬季季节部署研究，旨在研究美国大西洋沿岸的暴风雪（2020-2023年）。该考察旨在（1）提供理解雪带形成、组织和演化的关键观测；（2）探究雪粒的微物理特征及其可能的增长机制在雪带间的差异；（3）提升降雪的遥感解析和建模能力，以显著增强预测能力。数据以ASCII格式从2022年1月16日至2023年2月28日可供获取。
