ER-2 Navigation Data IMPACTS

The NASA ER-2 Navigation Data IMPACTS dataset contains information recorded by the onboard navigation and data collection systems of the NASA ER-2 high-altitude research aircraft. In addition to typical navigation data (e.g., date, time, latitude/longitude, and altitude) it also contains outside meteorological parameters such as wind speed, wind direction, and temperature. These data were collected during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign, 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. The IMPACTS navigation dataset files are available from January 15, 2020, through March 2, 2023, in ASCII-ict format.

NASA ER-2 高空研究飞机的导航数据 IMPACTS 数据集收录了该飞机机载导航与数据采集系统的记录信息。该数据集不仅包含常规的导航数据（例如，日期、时间、纬度/经度以及高度），还包含了外部气象参数，如风速、风向和温度。这些数据是在“大西洋沿岸威胁性暴风雪的微物理和降水调查”（IMPACTS）野外考察期间收集的，该考察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。IMPACTS 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）考察雪粒子在雪带内的微物理特征及其可能的增长机制如何变化；（3）提升降雪遥感解释和建模能力，以显著增强预测能力。该 IMPACTS 导航数据集文件以 ASCII-ict 格式自 2020 年 1 月 15 日起至 2023 年 3 月 2 日止可供获取。
