ESMF is software for building and coupling weather, climate, and related models. The premise is that complicated applications should be broken up into smaller pieces, or components. A component is a unit of software composition that has a coherent function, and a standard calling interface and behavior. Components can be assembled to create multiple applications, and different implementations of a component may be available.
Stanford Exploration Project Library (SEPlib) is a software package that was developed to manipulate and process many types of geophysical data. It includes libraries for manipulating 2D and 3D data and pipe-fed command-line utilities. It has support for parallelization through MPI and OpenMP and supports connectors to other geophysical packages.
