Measured magnetotelluric data of site48 and site49

We provide the measured magnetotelluric data of site48 and site49. The data were collected by Phoenix V5-2000 and processed by SSMT2000.Site48.tbl and Site49.tbl are the calibration files for the two sites.Site48.ts3, Site48.ts4 and Site48.ts5 are the high-frequency, medium-frequency and low-frequency magnetotelluric data of site48.Site49.ts3, Site49.ts4 and Site49.ts5 are the high-frequency, medium-frequency and low-frequency magnetotelluric data of site49.For easier access and visualization, the original data were converted from their proprietary format into Microsoft Excel.The high-frequency, medium-frequency and low-frequency magnetotelluric time series data of Site 48 (files Site48.TS3, Site48.TS4, and Site48.TS5) are merged and converted into a single Excel file (Site48.xlsx) , containing the time-domain data of the Site 48.
