Abstract 

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. 

Instructions: 

First Dataset is in Matlab variables ('DataWidthFrekHourly','DataCenterWidthFrekHourly') consist of maximum window frequency values with homogenous ToF and 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).

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.
