ModEM Documentation¶
Welcome to the ModEM’s documentation! ModEM is a modular system for inversion of electromagnetic geophysical data.
ModEM was designed as a flexible electromagnetic modeling and inversion system, written in Fortran 95. A primary design goal of the system was to allow simplified extension with regard to data types, modeling codes, parameterization and regularization, and inversion search algorithms (see Egbert and Kelbert, 2012; Kelbert et al., 2014). Although the code can be (and has been) extended for inversion of more general types of EM data (e.g., controlled source, DC; see Meqbel and Ritter, 2015), here we describe the stable, core system developed for 2D and 3D magnetotelluric (MT) problems. The stable MT program has a command-line interface, which controls available program options, and specifies required and optional input and output files.
