UAlbany Micro Rain Radar 2 (MRR-2) IMPACTS

The UAlbany Micro Rain Radar 2 (MRR-2) IMPACTS dataset consists of reflectivity, Doppler velocity, signal-to-noise ratio, spectral width, droplet size, Liquid Water Content, melting layer, drop size distribution, rain attenuation, rain rate, and radial velocity data collected 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. The MRR-2 instrument was used to collect data for this dataset. The dataset files are available from January 30, 2020, through February 28, 2023, in netCDF-3 and netCDF-4 format.

该阿尔巴尼大学微雨雷达2（MRR-2）IMPACTS数据集包含在调查大西洋沿岸威胁性暴风雪微物理和降水（IMPACTS）野外考察期间收集的反射率、多普勒速度、信噪比、频谱宽度、液滴尺寸、液态水含量、融化层、液滴尺寸分布、雨衰减、雨量和径向速度数据。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（2020-2023年）。此次考察旨在：（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数据；（2）探究雪粒子在雪带中的微物理特征及其可能增长机制的变化；（3）提升降雪遥感解释和建模能力，显著推进预测技术。MRR-2仪器被用于收集构成该数据集的数据。数据集文件以netCDF-3和netCDF-4格式提供，可供下载的日期从2020年1月30日至2023年2月28日。
