High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) IMPACTS

The High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) IMPACTS dataset consists of Equivalent reflectivity factor, Doppler velocity, Doppler velocity spectrum width, Linear Depolarization Ratio (LDR), Ocean normalized radar cross-section, Co-polarization signal-to-noise mask estimates collected by the HIWRAP onboard the NASA ER-2 aircraft 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. These data are available from January 25, 2020, through February 28, 2023, in HDF-5 format.

该高海拔成像风和雨机载剖面仪（HIWRAP）IMPACTS数据集包含等效反射率因子、多普勒速度、多普勒速度谱宽、线性去极化比（LDR）、海洋标准化雷达截面、共极化信噪比掩模估计，这些数据由搭载于NASA ER-2飞机上的HIWRAP在“对大西洋沿岸威胁性暴风雪的微物理和降水调查”（IMPACTS）现场考察期间收集而来。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。该项目的目标包括：（1）提供对理解雪带形成、组织和发展机制至关重要的观测数据；（2）探讨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）提升降雪遥感解释和建模能力，以显著提高预测能力。这些数据自2020年1月25日起至2023年2月28日止，以HDF-5格式提供。
