Interplanetary shock data base

<p>This interplanetary shock data base was compiled with Wind, Advanced Composition Explorer (ACE), and Deep Space Climate Observatory (DSCOVR) observations collected at the Lagrangian point L1. The list ranges from January 1995 to December 2024 with 650 events. Many shock parameters are included, such as shock impact angle, shock speed, Mach numbers, compression ratios, and IMF (interplanetary magnetic field) Bz in the upstream and downstream regions. The list also brings geomagnetic activity information such as minimum SMR values in a time interval of 2 hours after shock impact. The author intends to update this list annually.</p> <p>There are three files: (i) full_shock_list_2024.txt, a text file with &nbsp;650 events; (ii) full_shock_params.cdf, a cdf file with detailed information about each specific shock events; and (iii) read_shock.py, a file that contains a short python routine to read information about a specific shock event.
