Description:
The MT repository contains geophysical data sets collected in field experiments from all over the world. The acronym MT stands for magnetotelluric, a geophysical method used to probe the Earth's deep interior for its electrical conductivity distribution through electromagnetic (EM) induction. MT is based on EM fields generated by natural processes in the Earth's atmosphere and magnetosphere. But the repository also contains data from Controlled Source Electromagnetic (CSEM) projects, for which man-made EM sources are used. The principle form of data in the repository are time-series of EM field components acquired with heterogeneous sets of sensors, recording instruments, and sampling rates. It is the main purpose of this archive or repository to provide the links between the data and their physical meaning by means of metadata. To achieve this, the repository is organized as a combination of data files and associated meta-data in a well defined folder (directory) structure, with the data files being sorted into subfolders. Meta-data are provided as XML (Extensible Markup Language) formatted file.
