Lightning Instrument Package (LIP) IMPACTS V2

The Lightning Instrument Package (LIP) IMPACTS dataset consists of electrical field measurements of lightning and navigation data collected by the Lightning Instrument Package (LIP) flown 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 (2020-2023). 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 V2 LIP IMPACTS data have been further filtered to remove field mill offsets that were identified in the prior V1 data. These data are available from January 15, 2020, through March 2, 2023, in ASCII format.

雷电测量仪器包（LIP）IMPACTS数据集包含了在NASA ER-2飞机上搭载的雷电测量仪器包（LIP）收集的雷电电场测量数据和导航数据，这些数据是在对大西洋沿岸威胁性暴风雪的微物理和降水进行的实地考察（IMPACTS）活动中收集的。IMPACTS活动是一个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）。该活动的目标是：（1）提供对了解雪带形成、组织和发展机制至关重要的观测数据；（2）考察雪粒的微物理特征及其可能的增长机制在雪带中的变化情况；（3）改进降雪遥感解释和建模，以显著提升预测能力。V2版本的LIP IMPACTS数据已经过进一步筛选，以去除先前V1数据中识别出的场强仪偏移。这些数据以ASCII格式自2020年1月15日起至2023年3月2日可用。
