Magnetotelluric and Transient Electromagnetic data from the Main Ethiopian Rift (NERC Grant NE/L013932/1)

This data set includes the original time series collected with broadband and long-period MT instruments during two field seasons in 2016 and 2017 by a team of researchers from the University of Edinburgh, UK and the Institute for Geophysics, Space Science and Astronomy at Addis Ababa university, Ethiopia. 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.

Statement: Broadband Magnetotelluric (BMT) data were collected with Phoenix MTU5A systems, owned by Dublin Institute for Advanced Studies. Long period data (LMT) were recorded using LEMI-417 also owned by Dublin Institute for Advanced Studies. The processing for the BMT data after Egbert, G. D. (1997). Robust multiple?station magnetotelluric data processing. Geophysical Journal International, 130(2), 475–496. LMT data were processed with Smirnov, M. Y. (2003). Magnetotelluric data processing with a robust statistical procedure having a high breakdown point. Geophysical Journal International, 152(1), 1–7. 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.
