Interplanetary shock data base

This interplanetary shock data base was compiled with Wind and Advanced Composition Explorer (ACE) observations collected at the Lagrangian point L1. The list ranges from January 1995 to May 2023 with 603 events. There are 590 events up to December 2022. 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. There are three files: (i) full_shock_list_2023.txt, a text file with ev603ents; (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. The SpacePy package (https://spacepy.github.io/spacepy.html#:~:text=SpacePy%3A%20Space%20Science%20Tools%20for,at%20the%20space%20science%20community.) is required to extract shock information from the cdf file.
