Langmuir probe data of SNIPE-B during superstorm between May 10 and 12, 2024.

The SNIPE mission organized by Korea Astronomy and Space Science Institute (KASI) was designed to investigate microscale plasma structures in the Earth’s ionosphere and the magnetosphere. The mission consists of four 6U CubeSats, each weighing approximately 10 kg. The SNIPE constellation was launched on May 25, 2023, from the Naro Space Center in South Korea using a Nuri (KSLV-II) rocket. The Langmuir probe of SNIPE-B successfully observes the May 2024 geomagnetic storm. The dataset is electron density(Ne) and electron temperature(Te). In addition, geographic latitude (GLAT), geographic longitude (GLON), altitude (ALT), magnetic latitude (MLAT), and magnetic local time (MLT) are included. The data period is from 2024-05-10 9:38:46 to 2024-05-12 21:26:05.由韩国天文与空间科学研究所（Korea Astronomy and Space Science Institute, KASI）牵头实施的SNIPE任务，旨在探测地球电离层与磁层内的微尺度等离子体结构。该任务配置4颗6U立方星（CubeSats），单颗质量约10千克。SNIPE星座于2023年5月25日在韩国罗老航天中心，由“纽里”（Nuri，KSLV-II）运载火箭发射升空。其中SNIPE-B搭载的朗缪尔探针（Langmuir probe）成功观测到2024年5月发生的地磁暴。本数据集涵盖电子密度（electron density, Ne）与电子温度（electron temperature, Te），此外还包含地理纬度（geographic latitude, GLAT）、地理经度（geographic longitude, GLON）、海拔高度（altitude, ALT）、磁纬度（magnetic latitude, MLAT）以及磁地方时（magnetic local time, MLT）。数据覆盖时段为2024年5月10日9时38分46秒至2024年5月12日21时26分05秒。
