MT 3D Inversion Workshop: Dublin Test Model 1 (DTM1) Responses

At the moment only ascii format impedance or resistivity and phase files are available. The first line is a header line - the used sign convention for the time dependency is e^iωt.

• Nuree Han & Tae Jong Lee:
  Myung Jin Nam’s code ( Nam, M. J., Kim, H. J., Song, Y., Lee, T. J., Son, J. S., and Suh, J. H., 2007, 3D magnetotelluric modelling including surface topography, Geophysical Prospecting, 55, 277-287) - impedances or resistivities & phases.
  
  
• Randy Mackie:
  Randy Mackie’s code  - impedances or resistivities & phases.
  
  
• Marion Miensopust:
  
  1. Winglink ( Mackie, R. L., Smith, J. T., & Madden, T. R. (1994). Three-dimensional electromagnetic modeling using finite difference equations: The magnetotelluric example. Radio Science, 29, 923–935 ) - impedances or resistivities & phases.
  2. wsinv3dmt (Siripunvaraporn W., G. Egbert and Y. Lenbury, 2002, Numerical Accuracy of      Magnetotelluric Modeling: A Comparison of Finite Difference Approximation, /Earth Planets Space/, 54, 721-725) - impedances or resistivities & phases. (Please note, due to the conflict of sites being located on top of the body edges and this code requiring the sites to be in the centre of the cells, boundaries had to be moved slightly -> not 100% identical to all other responses.)
  3. UBC GIF code mt3dinv (Farquharson, C. G., Oldenburg, D. W., Haber, E., & Shekhtman, R. (2002, October). An algorithm for the three-dimensional inversion of magnetotelluric data. SEG Int’l Exposition and 72nd Annual Meeting, Salt Lake City, Utah) - impedances or resistivities & phases.
