“…IRIS Portable Array Seismic Studies of the Continental Lithosphere (PASSCAL) also developed an HDF5 container the PASSCAL hierarchical format (PH5), which is their contemporary format to archive seismic data for large assembled datasets. We pursued extending ASDF and PH5 but decided to build a specific container for MT data (MTH5) that could potentially be an extension in the future to ASDF, PH5, and the planned geophysical format being developed by IRIS and UNAVCO, which will be a flexible format to store various types of geophysical data (Habermann et al, 2021). MTH5 is an HDF5 file and the open-source Python module mth5 provides tools to interface with the file.…”

Magnetotellurics (MT) is a passive electromagnetic geophysical method that measures variations in subsurface electrical resistivity. MT data are collected in the time domain and processed in the frequency domain to produce estimates of a transfer function representing the Earth's electrical structure. Unfortunately, the MT community lacks metadata and data standards for time series data. As the community grows and findability, accessibility, interoperability, and reuse of digital assets (FAIR) data principles are enforced by government and funding agencies, a standard is needed for time series data. Presented here is a hierarchical data format (MTH5) that is logically formatted to how MT data are collected. Open-source Python packages are also described to read, write, and manipulate MTH5 files. These include a package to deal with metadata (mt_metadata) based on standards developed by the Working Group for Magnetotelluric Data Handling and Software assembled by the Incorporated Research Institutions for Seismology (IRIS), and mth5: a package to interact with MTH5 files that uses mt_metadata. Example code and workflows are presented.
