Shock database

The SHARP shock database is open for everyone to use. When using the data in publications of any form please use the following acknowledgment:

"The shock parameters were obtained from https://sharp.fmi.fi/shock-database/ and developed in the SHARP project, funded by the European Union under grant agreement number 101004131."

Shock database selection

Build your shock database.
To see a list of all available data (6112 shocks), click 'Submit' without selecting anything.
To limit and specialise your database, select any spacecraft mission and/or adjust any parameter range, before clicking 'Submit'.
If 'Include shocks without ... value' for a certain parameter is unchecked, shocks where the corresponding parameter value is unavailable will not be included.
Note: It is not recommended to use the 'back' and 'forward' buttons on your browser, as the website may not work properly using them.
