Subject GNSS TEC, ionogram, S4 index data
Publisher Xiukuan Zhao
Description The GNSS data and ionosonde data are from IONISE, IGS and CMONOC. TEC and the rate of TEC index (ROTI, computed for each 300-second interval and converted to the unit of TECu/min) with elevation angles lager than 30° were calculated. The ionosonde ionograms obtained at Beijing (116.2°E, 40.3°N, dip Lat, 39.4°), Wuhan (114.5°E, 31.0°N, dip Lat, 28.0°) and Ledong (109.0°E, 18.4°N, dip Lat, 12.9°) with temporal resolutions of 15 min, 15 min and 1 min respectively were manually scaled to get the background ionospheric condition at different latitudes.
The Bz and Dst index were downloaded from the National Geophysical Data Center website (https://www.ngdc.noaa.gov). The magnetometer data were downloaded from BCMT (http://www.bcmt.fr/). AIRS data are distributed by the NASA Goddard Earth Sciences Data Information and Services Center (DISC).
