Frequency Window of NVIS Channel from Kupang Ionosonde Year 2022

This dataset was obtained from the ionogram at Kupang in 2022 to investigate the frequency window of the Near Vertical Incidence Skywave (NVIS) channel with homogenous Time of Flight (ToF) values. All data is in the form of.mat files (MATLAB). The first dataset is in Matlab variables ('DataWidthFrekHourly','DataCenterWidthFrekHourly'), which consist of maximum window frequency values with homogenous ToF and the center frequency of the widest window. The structure of the data array is 96x365, with the row as the time (1:96) and the column as the day in one year (1:365). The second dataset is compressed data in the form of a Matlab variables file ('nil_widthf','nilToFnya') with information on the widest frequency window hourly every day in 2022 and its ToF values.

本数据集源自2022年库邦站的电离层图，旨在探究具有均匀飞行时间（ToF）值的近垂直入射天波（NVIS）通道的频率窗口。所有数据均以.mat文件格式（MATLAB）存储。首个数据集包含Matlab变量('DataWidthFrekHourly','DataCenterWidthFrekHourly')，其中记录了具有均匀ToF值的最大窗口频率及其最宽窗口的中心频率。数据数组的结构为96x365，行代表时间（1:96），列代表一年中的每一天（1:365）。第二个数据集为压缩的Matlab变量文件('nil_widthf','nilToFnya')，其中包含2022年每日每小时最宽频率窗口及其ToF值的信息。
