Description

The archive inside the file jetset.tgz contains a database of jets observed at Mars by the Maven spacecraft. The database is described and analysed in the paper "Jets downstream of the Martian bow shock: Occurrence during the 2014-2024 period" by Tara Mohammed-Amin, Eva Krämer, Sara Nesbit-Östman, Herbert Gunell, and Cyril Simon Wedlund.

 

The database consists of comma-separated ASCII files, one file per month,
and in the file there is one jet per row.
The following variables correspond to each column:

% general properties
tstart  : start time of the jet.
tstop   : end time of the jet
