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. 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.
While 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). The stable MT program has a command-line interface, which controls available program options, and specifies required and optional input and output files.
