SEISglitch
SEISglitch is a seismological Python package based on the ObsPy library. Its purpose is to handle “glitches” - also referred to as “long-period data disturbances” - present in the raw seismic data of the VBB (very broadband) and SP (short period) seismometers, both part of the SEIS instrument of NASA’s “InSight” Discovery mission to planet Mars. The package allows to detect and remove glitches from the seismic raw data, and provides plot funtionality to analyse their behaviour in detail. SEISglitch corresponds to the ‘MPS’ method detailed in Scholz et al. (2020, see below). All other methods (‘ISAE’, ‘UCLA’, ‘IPGP’) were implemented in MATLAB and their essential scripts are also shipped with this software. SEISglitch further comes with some useful features to ease data handling, e.g. download, processing, and time conversion. Potentially, major functionalities of this toolbox could also be used to treat the same data disturbances occurring on other seismic stations, however, this has not been tested.
The package is based on the following, peer-reviewed paper:
Scholz, J.‐R., Widmer‐Schnidrig, R., Davis, P., Lognonné, P., Pinot, B., Garcia, R. F.,
et al. (2020). Detection, analysis and removal of glitches from InSight’s seismic
data from Mars. Earth and Space Science, 7, e2020EA001317‐T.

If you find seisglitch useful, used the MATLAB alternatives, corrected data as to the considerations outlined in the paper, or
used the corrected data provided along with this package, please consider citing this and the following paper:

Mars from InSight Seismic Data.” Nature Geoscience 13, no. 3 (March 2020), 213–20.

You can also help the Obspy developers by citing their work that the seisglitch package heavily relies on.
Note: Along with this package also come deglitched data for a selection of seismic events. These corrected raw data will automatically be on your machine if you follow the Installation. If you just want to quickly download the deglitched data, go here.
