May2024_TEC_satellite_data

Swarm, DMSP, CSES, and CSS satellite data used in this study are archived as per-orbit files in the subdirectories 'Swarm', 'DMSP', 'CSES', and 'CSS', respectively. For these per-orbit files, the key plasma density variables used in this study are:- DMSP: 'sum_Ion_density' (total ion density, cm⁻³)- Swarm: 'electron_density' (electron density, cm⁻³)- CSS: 's_denity_O' (O⁺ ion density, m⁻³)- CSES: 'A311' (electron density, m⁻³) Geographic and geomagnetic coordinates (e.g. 'geoLongitude', 'geoLatitude', 'magLatitude') follow directly from their column names in each file. The subdirectory 'TEC' contains gridded TEC maps for the storm interval with a temporal resolution of 5 minutes. Each file in this folder (e.g. '2024-05-10 00-00-00_5min.parquet', '2024-05-10 00-05-00_5min.parquet') corresponds to a single epoch and is stored in parquet format. For each epoch, the file provides one TEC map with the following columns: 'geo_Longitude', 'geo_Latitude', and 'tec'. All datasets in this repository are provided in standard file formats ('*.parquet' and '*.pkl') that can be easily read in Python using, for example, pandas ('read_parquet') and the standard 'pickle' module.
