For the magnetotelluric stations, processed transfer functions are included in the edi file format. The time series data is provided both in the original raw data format and an ascii version. We provide information on the locations and the processing and include the necessary instrument response functions and metadata to reproduce our results from the raw data. For the TEM recordings, site coordinates and raw data are included in the original format.

The TEM data were collected at 15 sites using a Geonics TEM58 RX owned by the NERC Geophysical Equipment Facility in Edinburgh, UK. Originally it was intended to collect data at all MT site locations, but this was not possible due to the political situation during the field campaign in 2016.
