Contents in the main package (ln_solver2.3.tar.gz) is divided into two components; dynamical model and matrix solver. All the programs contained is written in Fortran, and the model part has been constructed based on a dynamical core of AGCM cooperatively developed at Center for Climate System Research (CCSR), University of Tokyo, and National Institute for Environmental Studies (NIES), called CCSR/NIES AGCM, version 5.4g. The spectral representation of primitive equations with a vertical sigma coordinate has been explicitly linearized about basic state. Since the model is, in most cases, used with multiple levels although a single-layer model (barotropic model) is available as well, it is hereafter referred to as the linear baroclinic model (LBM) in this package. The form of linear equations are given by Watanabe and Kimoto (2000, 2001) and also briefly described in the Appendix of the document.
