Data for publication "Development and cancellation of long-duration positive ionospheric storms: both changes of the F2-layer peak height and O/N2 ratio can be decisive".

These data archives include the dataset and the Field Line Interhemispheric Plasma (FLIP) model software used in the manuscript“Development and cancellation of long-duration positive ionospheric storms: both changes of the F2-layer peak height and O/N2 ratio can be decisive".#1 The data archive "Figures in manuscript" contains a README file and a dataset to plot figures in the manuscript.Data files in CSV (comma-separated values) and txt format contain modeling and observational values. Modeling values obtained from the FLIP model.Observational values consist of ionosonde, digisonde, GNSS receivers (TEC), and the Global Ultraviolet Imager (GUVI) on the NASA Thermosphere Ionosphere Mesosphere Energy and Dynamics (TIMED) satellite measurements (O/N2). The planetary geomagnetic index (Kp) is from the World Data Center for Geomagnetism, Kyoto.The SYM/H index and zonal component of the magnetospheric electric field are taken from the OMNIWeb. Data files contain data from February 25 to March 1, 2023.#2 The data archive "FLIP model and simulations" contains a README file, the FLIP model software, and four folders with simulation results associated with the manuscript. #3 The data archive "Kharkiv_ionosonde_data" contains raw ionosonde data from Kharkiv ionosonde for the period from February 25, 2023 to March 1, 2023.#4 The data archive "GIRO_Grahamstown data contains a README file and the Grahamstown digisonde dataset retrieved from the GIRO database from February 25, 2023 to March 1, 2023.本数据集档案包含论文《长时间电离层正暴的发展与消散：F2层峰值高度与O/N2比值均可成为决定性因素》中所使用的数据集与场线跨半球等离子体（Field Line Interhemispheric Plasma, FLIP）模型软件。#1 "论文配图"数据集档案包含README文件与用于复现论文插图的配套数据集。其中CSV（逗号分隔值）与TXT格式的数据文件收录了模型模拟值与观测值：模型模拟值由FLIP模型生成；观测值则涵盖电离层测高仪、数字电离层测高仪、GNSS接收机（总电子含量，Total Electron Content, TEC）的观测数据，以及美国国家航空航天局（NASA）热层-电离层-中间层能量与动力学（Thermosphere Ionosphere Mesosphere Energy and Dynamics, TIMED）卫星搭载的全球紫外成像仪（Global Ultraviolet Imager, GUVI）所测得的O/N2比值数据。行星地磁指数（Kp）源自京都世界地磁数据中心。SYM/H指数与磁层电场纬向分量取自OMNIWeb数据库。本数据集覆盖2023年2月25日至3月1日的相关数据。#2 "FLIP模型与模拟结果"数据集档案包含README文件、FLIP模型软件，以及四个用于存储与本论文相关的模拟结果的文件夹。#3 "哈尔科夫电离层测高仪数据"数据集档案包含2023年2月25日至3月1日期间的哈尔科夫电离层测高仪原始观测数据。
