Ionospheric data from GPS and IRI-2016 model

This was collected by a SCINDA GPS receiver installed at Helwan University, Cairo in Egypt which is near the northern crest of the Equatorial Ionisation Anomaly. The receiver was installed by the SCINDA project during the implementation of the International Heliophysical Year program in 2009. The recording of data started in July 2009 up to August 2017 before the receiver become faulty. The actual raw files were preprocessed to textfiles for each year named "Myfiletec'year'".
There are 9 text files each with 5 columns of data in the order of DOY, hh, mm, TEC, SI representing doy of the year, hour, minute, total electron content, and scintillation index respectively.

The IRI data was got from the Community Coordinated Modeling Center (https://ccmc.gsfc.nasa.gov/models/modelinfo.php?model=IRI) by running year requests from 20009 to 2017. The text files contained the parameters in the following order of year, month, day, hour, minute, second, geographical positions (longitude & latitude), height, electron density, ,TEC, and peak density (NmF2).

本数据集由位于埃及开罗赫尔万大学的SCINDA GPS接收器收集，该接收器位于赤道电离异常北部隆起附近。该接收器是在2009年实施国际地球物理年计划期间，由SCINDA项目安装的。数据记录始于2009年7月，直至2017年8月接收器出现故障为止。原始数据文件经过预处理，每年生成名为“Myfiletec'year'”的文本文件。每个文本文件包含5列数据，依次为：当日序数（DOY）、小时（hh）、分钟（mm）、总电子含量（TEC）和闪烁指数（SI），分别代表年份的当日序数、小时、分钟、总电子含量以及闪烁指数。IRI数据通过社区协调建模中心（https://ccmc.gsfc.nasa.gov/models/modelinfo.php?model=IRI）获取，从2009年至2017年按年请求运行。文本文件包含以下参数，顺序为：年份、月份、日期、小时、分钟、秒、地理位置（经度 & 纬度）、高度、电子密度、TEC和峰值密度（NmF2）。
