This repository contains scripts for InSight seismic data download and processing. The scripts download the VBB SEIS instrument data for the seismic events that are listed in the Marsquake Catalog. The scripts are developed by the University of Maryland InSight group, whereas the instrument and marsquake events information are provided by working groups of the InSight team and should be cited appropriately, according to the information provided below.

In order to use this suite, a python3 installation in your system is necessary, as well as the ObsPy open sourced framework. Please acknowledge and cite the ObsPy references accordingly.
This repository contains:
- The 12th version of the Marsquakes Catalog. Citation: InSight Marsquake Service (2022). Use the link for the download and cite accordingly.
- The ELYSE station dataless file. Citation: InSight MARS SEIS Data Service (2019). Use the link for the download and cite accordingly.
- The python script make_seismic_catalog.py that creates the text file of the catalog, needed for the event data downloaders.
- The python script eventdownloader.py, which is used for downloading and processing of a unique event data.
- The python script massivedownloader.py, which is used for downloading and processing of events' data of a specific event Type and Quality (see Clinton et al., 2021 for details).
make_seismic_catalog.py: Just run the script and the SeismicCatalog text file will be generated.
eventdownloader.py: When asked to input the event, write the full event name. For example, to download the S1222a event, write S1222a.
massivedownloader.py: When asked to input the Quality, write A, B, C, or D. When asked to input the Class, write the name of the class in the way that it is written in the SeismicCatalog text file, which means LOW_FREQUENCY, BROADBAND, 2.4_HZ, HIGH_FREQUENCY, and VERY_HIGH_FREQUENCY. For example, to download the A quality BROADBAND events, write A for the Quality input, and BROADBAND for the Class input.
The output files of the suite are saved in a directory that has the following format in your system: DATA/Event_Type/Event_Quality/Event_Name/. There are 4 mseed files:
- The raw data mseed file, named Event_Name.mseed
- The event data with instrument response removal, rotation to Z, N, E and the application of a Tukey window filter, with the 5% of the timeseries within the sinusoidal function, named Event_Name_DISP.mseed for displacement, Event_Name_VEL.mseed for velocity and Event_Name_ACC.mseed for acceleration.
The Event_Name is given in the Marsquake Catalog and is defined by an alphanumeric digit for the type of the Event (S for seismic events), 4 digits for the Sol (Martian Day of InSight operations) and one alphanumeric digit for the order of the event within the indicated sol.
The Event_Type and the Event_Quality are the Type and Quality of the event respectively, as defined by Clinton et al., 2021.
The scripts of this repository download Mars InSight seismic data from IRIS. It is developped by Foivos Karakostas, Doeyeon Kim, Ross Maguire, Aisha Khatib, Quancheng Huang, Angela Marusiak, Nicholas Schmerr, Ved Lekić and the University of Maryland InSight group. Please acknowledge.
