Multi-Radar/Multi-Sensor (MRMS) Precipitation Reanalysis for Satellite Validation Product IMPACTS V1

The Multi-Radar/Multi-Sensor (MRMS) Precipitation Reanalysis for Satellite Validation Product IMPACTS dataset contains reflectivity products using the MRMS system 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 significantly advance prediction capabilities. Data are available from January 1, 2022, through March 2, 2023, in netCDF-4 format.

《多雷达/多传感器（MRMS）卫星验证产品降水再分析》数据集，包含在“对大西洋沿岸威胁性暴风雪的微物理和降水研究”（IMPACTS）现场考察期间，利用MRMS系统生成的反射率产品。IMPACTS项目是一项为期三年的冬季季节部署序列（2020-2023），旨在研究美国大西洋沿岸的暴风雪。该考察旨在（1）提供对雪带形成、组织和发展机制理解至关重要的观测数据；（2）考察雪粒子在雪带中的微物理特性和可能的增长机制如何变化；（3）改进降雪遥感解释和建模，以显著提升预测能力。数据以netCDF-4格式提供，时间范围从2022年1月1日至2023年3月2日。
