NASA S-Band Dual Polarimetric Doppler Radar (NPOL) IMPACTS V1

The NASA S-Band Dual Polarimetric (NPOL) Doppler Radar IMPACTS dataset consists of rain rate, reflectivity, Doppler velocity, and other radar measurements obtained from the NPOL radar during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. The goal of IMPACTS was to provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution, examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands, and improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The IMPACTS NPOL data are available from January 10, 2020 thru February 25, 2020. Zipped data files are in netCDF-3/CF format and contain corrected radar reflectivity, differential reflectivity, specific differential phase, differential phase, co-polar correlation, and Doppler velocity images.

美国国家航空航天局（NASA）S波段双极化（NPOL）多普勒雷达的IMPACTS数据集，包含在针对大西洋沿岸威胁性暴风雪的微物理和降水调查（IMPACTS）现场活动期间，由NPOL雷达获得的降雨率、反射率、多普勒速度以及其他雷达测量数据。IMPACTS项目旨在提供对理解雪带形成、组织及演化的机制至关重要的观测数据，探讨雪粒子在雪带中的微观物理特性及其可能的增长机制如何变化，并提高降雪远程传感的解读和建模，以显著提升预测能力。该IMPACTS NPOL数据集可供使用的时间范围为2020年1月10日至2020年2月25日。数据文件以netCDF-3/CF格式压缩，包含校正后的雷达反射率、差分反射率、特定差分相位、差分相位、共极相关以及多普勒速度图像。
