Rapid X-band Polarimetric Radar (RaXPol) IMPACTS

The Rapid X-band Polarimetric Radar (RaXPol) IMPACTS dataset consists of data measured from the RaXPol instrument 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 significantly advance prediction capabilities. The RaXPol dataset consists of various reflectivity variables. RaXPol data are available from January 29, 2022, through January 25, 2023, in netCDF-4 format.

快速X波段极化雷达（RaXPol）IMPACTS数据集由在调查大西洋沿岸威胁性暴风雪微物理和降水的IMPACTS实地考察期间，由RaXPol仪器测量的数据组成。IMPACTS是一项为期三年的冬季季节部署序列，旨在研究美国大西洋沿岸的暴风雪。该研究旨在（1）提供对理解雪带形成、组织和演变的机制至关重要的观测；（2）探究雪粒的微物理特征及其可能的生长机制在雪带间的差异；（3）提升降水的遥感解释和建模能力，以显著推进预测能力。RaXPol数据集包括多种反射率变量。RaXPol数据以netCDF-4格式从2022年1月29日到2023年1月25日均可获得。
