Replication Data for Day-to-day Variability of Field-Aligned Irregularities Occurrence in Nighttime F-region Ionosphere over the Equatorial Atmosphere Radar: A Combinatorics Analysis

This dataset consists of an ASCII file that contains the tabulated states of field-aligned irregularities (FAI) occurrence for each calendar date in 2011-2013, and a PDF file with summary tables listing the prevalence of various day-to-day combinatorics patterns obtained from the analysis. The FAI occurrence tabulation was based on examination of signal-to-noise ratio (SNR) values of coherent backscattered power observations by the Equatorial Atmosphere Radar (EAR) at Kototabang, West Sumatra, Indonesia. For each date, it is either a confirmed FAI occurrence (+), or a confirmed FAI no-occurrence (-), or an unknown (?) when we have missing/incomplete EAR observation data. The summary tables in the PDF file show full list of statistical likelihood values of each combinatorics pattern (from 1-day to 6-day patterns) for the two equinoxes and the two solstices.
