A global database for openly available electromagnetic transfer functions (EMTFs), including the entirety of the USMTArray survey (see also the Eos article Mapping the Hidden Electrical Anatomy of a Continent), completed by Oregon State University. USMTArray itself is a compilation of several projects. The database also includes other community datasets and provides magnetotelluric impedances and tippers, as well as other frequency-domain electromagnetic data.
Click on a row to display details for that EMTF site. Use the filter controls below to limit sites by name, ID, project, survey, quality, etc. For more information about the EMTF Data Product, visit the Magnetotelluric Transfer Functions product page.
This database is documented by Kelbert et al. (2018).
The EMTF XML format and file conversion utilities are described by Kelbert (2019). Reading and writing of EMTF XML is supported by EMTF FCU.
All data are oriented to geographic coordinates, but all historical files are also available in their original orientations. Please see the complete change log for database changes.
Data citations are provided for each survey; these should be referenced in publications.
