ACHIEVE W-Band Cloud Radar IMPACTS

The ACHIEVE W-Band Cloud Radar IMPACTS dataset consists of reflectivity, signal-to-noise ratio, and radial velocity data measured 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. IMPACTS 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. ACHIEVE W-Band Cloud Radar data are available from January 23, 2023, through March 1, 2023, in netCDF-4 format.

ACHIEVE W-Band 云雷达IMPACTS数据集，包括在调查大西洋沿岸威胁性暴风雪微物理和降水（IMPACTS）现场活动期间测量的反射率、信噪比和径向速度数据。IMPACTS是一项为期三年的冬季部署序列，旨在研究美国大西洋沿岸的暴风雪。IMPACTS旨在（1）提供对理解雪带形成、组织和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可能的增长机制在雪带中的变化情况；（3）改善降雪遥感解释和建模，以显著提升预测能力。ACHIEVE W-Band云雷达数据自2023年1月23日起至2023年3月1日止，以netCDF-4格式提供。
