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 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.

Observing spacecraft(s):

(If none selected, all will be included.)

Data mode:

(If none selected, all will be included.)

Adjust one or more parameter ranges:
(The pre-filled default values correspond to the lowest and highest values in the current database.)
