High-latitude Input for Meso-scale Electrodynamics (HIME)

High-latitude Input for Meso-scale Electrodynamics: HIME, is a new framework that is developed to account for the local meso-scale electric field variability in a global I-T model, so that their role during certain intervals and locations can be analyzed. This data set consists of local 2D electric field estimates from PFISR (provided in 20170302.002_lp_1min-cal_2dVEF_001001_NoLonely-geo600km.h5), and HIME generated drivers. These drivers were generated by first calculating the electric potentials with Forward Euler formula from PFISR estimates and through their merging with a global empirical model (in this case Weimer model) to specify upper boundary conditions for a global I-T model (in this case University of Michigan Global Ionosphere Thermosphere Model). More information on HIME can be found in the accompanying article.

中尺度电动力学高纬度输入框架（High-latitude Input for Meso-scale Electrodynamics, 缩写HIME）是一套全新研发的框架，旨在解决全球电离层-热层（Ionosphere-Thermosphere, I-T）模型中的局地中尺度电场变异性问题，以便分析其在特定时段与区域内的作用。该数据集包含来自扑克平地非相干散射雷达（Poker Flat Incoherent Scatter Radar, PFISR）的局地二维电场估算数据（对应文件名为20170302.002_lp_1min-cal_2dVEF_001001_NoLonely-geo600km.h5），以及HIME生成的驱动场。上述驱动场的生成流程为：首先基于PFISR的电场估算结果，通过向前欧拉公式计算电势，并将其与全球经验模型（本案例采用Weimer模型）融合，以此为全球I-T模型（本案例采用密歇根大学全球电离层-热层模型）指定上边界条件。关于HIME的更多信息可参阅配套学术论文。
