Vapor In-Cloud Profiling Radar (VIPR) datasets

NASA’s Vapor In-cloud Profiling Radar (VIPR) is a tunable G-band radar designed for remote sensing of humidity within clouds and precipitation. VIPR estimates humidity using the differential absorption radar (DAR) technique. These files contain radar reflectivity data and humidity estimates from measurements collected during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) campaign and the Synergies of Active Optical and Active Microwave Remote Sensing Experiment (SOA2RSE) campaign. Documentation is limited, but Millan et al. (2024, doi: 10.5194/amt-17-539-2024) provides a detailed description of the instrument and the associated data.美国国家航空航天局（National Aeronautics and Space Administration，NASA）的云内水汽廓线雷达（Vapor In-cloud Profiling Radar，VIPR）是一款可调谐G波段雷达，专为开展云层及降水内部湿度的遥感探测而设计。VIPR采用差分吸收雷达（differential absorption radar，DAR）技术开展湿度估算。本数据集包含来自大西洋沿岸暴雪微物理与降水研究（Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms，IMPACTS）外场观测项目，以及主动光学与主动微波遥感协同实验（Synergies of Active Optical and Active Microwave Remote Sensing Experiment，SOA2RSE）外场观测项目中采集的雷达反射率数据与湿度估算结果。 本数据集的配套文档较为有限，但Millan等人2024年发表的研究成果（doi: 10.5194/amt-17-539-2024）对该仪器及相关数据进行了详细说明。
