This data repository contains global TEC data from 14 - 16 January 2022 obtained from the GNSS-TEC database available at https://stdb2.isee.nagoya-u.ac.jp/GPS/GPS-TEC/ provided by the Institute for Space-Earth Environment Research, Nagoya University. The hourly data files are in netcdf format compressed with winrar into a single document (Data.rar). For easier inspection the matlab codes used for extraction from netcdf format are provided in the compressed file (ReadCodes_Matlab.rar). Run code Read_TEC_Data.m in the folder containg the data files. Detrended data matrix, dTEC1 is used in this work.
