The core model equations and the non-core equations are available in ASCII format. These files contain the equations presented in Appendix A (core model) and Appendix B (non-core equations). The core and non-core equations are provided separately to reflect the way the core and non-core models interact (discussed in Chapter 4). In particular, to generate results using the non-core equations, the core model must be solved first to generate values for variables with the "core" superscript that appear in the non-core equations.
