title: Data set for manuscript "The Earth ionosphere disappeared in whole China during 2024 Mother’s Day Superstorm"

description: These data come from Chinese Meridian Project(CMP) and ISES Regional Warning Center of China.There are 4 types of data files:1) Ionograms on 10-12 May, 2024 of 14 ionosondes from CMP;'.png' files in folder 'IONOGRAM/YYYYmmdd/STAID/'.2) TEC maps over Chinese and adjacent region on 7-13 May, 2024 from ISES Regional Warning Center of China, with assimilated GNSS observations from CMP and International GNSS Services (IGS)[1];'.dat' files in folder 'TEC/YYYYmmdd/';The grided TEC files include the following spatial resolution:(Line 1-8: Head)Line 9-49: TEC at latitude 55oN, 54oN, 53oN, ..., 15oN;Column 1-71: TEC at longitude 70oE, 71oE, 72oE, ..., 140oE;3) Observations on 10-12 May, 2024 of the Incoherent Scatter Radar (ISR) in Sanya (109.63oE, 18.35oN), 2024 from CMP;'.h5' files in folder 'ISR/YYYYmmdd/OSAYA/';The related parameters for manuscript in SYISR .h5 files are following:Time, Beamdir, GEO, Fittedparameter;Where, time is observation universal time;Beamdir is the azimuth[o] and elevation[o] of different beam direction;GEO is the vector of position of each point in beam direction in (longitude[o], latitude[o], altitude[km]) coordinates;Fittedparameter consists of Ne[m-3], Ti[K], Te[K] and V[m/s] of each point along beam directions in the position of GEO.4) China region Dst index in May, 2024 calculated from four CMP geomagnetic stations[2];'cdst_202405.dat' file in folder 'cDst/';Parameters and formats of cDst.dat file are:Year, Month, Day, Hour, cDst, Dst;I4, X, I2, X, I2, X, I2, X, I7, X, I7;Where, time(Year-Month-Day, Hour) is universal time;'cDst' is the Dst indexes in China calculated with the geomagnetic data of the CMP in Lasa, Chengdu, Wuhan and Hangzhou stations;'Dst' is Dst index.
