Configurable Scanning Submillimeter-wave Instrument/Radiometer (CoSSIR) IMPACTS

The Configurable Scanning Submillimeter-wave Instrument/Radiometer (CoSSIR) IMPACTS dataset consists of data measured 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 significantly advance prediction capabilities. The CoSSIR dataset consists of measured ice clouds and brightness temperatures, water vapor profiles, and snowfall rates. CoSSIR data are available from January 5, 2023, through March 2, 2023, in netCDF-4 format.

CoSSIR可配置扫描亚毫米波仪器/辐射计数据集，系由美国国家航空航天局ER-2飞机在执行针对大西洋沿岸威胁性暴风雪的微物理和降水调查（IMPACTS）现场考察期间所采集的数据组成。该IMPACTS项目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。该项目旨在（1）提供对理解雪带形成、组织和演化的机制至关重要的观测数据；（2）探讨雪粒子的微物理特征及其可能的增长机制在雪带之间的差异；（3）改进降雪遥感解释和建模，以显著提升预测能力。CoSSIR数据集包括测量的冰云和亮度温度、水汽廓线以及降雪速率。CoSSIR数据以netCDF-4格式自2023年1月5日至2023年3月2日可供使用。
