This data repository contains global TEC processed data from 14 - 16 January 2022. The original data were 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 data is in .mat format (binary Matlab file) with the following data matrices:

Coordinates (geographic coordinates - Latitude, Longitude)

dTEC1 (detrended TEC)

TimeTEC_combined (time series absolute TEC for each geographic coordinate)

Data has a time resolution of 5 min in each column.
