The goal of MTH5 is to develop a standard format and tools for archiving magnetotelluric (MT) time series data.

The preferred format is HDF5 and has been adopted to conform to MT data, something that has been needed in the EM community for some time. The module mth5 contains reading/writing capabilities and will contain tools for retrieving data in useful ways to work with processing codes.

The metadata follows the standards proposed by the IRIS-PASSCAL MT Software working group and documented in MT Metadata Standards.

Note

This is a work in progress. Feel free to comment or send me a message at jpeacock@usgs.gov on the data format.

• The basic format of MTH5 is illustrated below, where metadata is attached at each level.
