Upgrades to the Parabolic Equation Model
Abstract
The PE model is a fully range dependent transmission loss algorithm based on a split-step Fourier solution of the standard parabolic approximation. Under this contract, many capabilities have been added to the PE model and they are outlined in this report. Major revisions include the addition of surface loss, the addition of bottom loss, the ability to modify the pressure field at any range, the option to perform a warm start run, and several input/output options. PE Version 2.2 was installed on the HP9050 and the SPERRY 1100/80 series computers at the Naval Oceanographic Office, Code 7300. The main body of this document describes the changes made to PE and how they were implemented. Appendix A gives a summary and description of each of the PE modules, Appendix B contains the PE input set description, Appendix C describes the PE Pre-processor input set, and Appendix D lists sample input and output files of the sample runs described in the body of this report. Appendix E gives the format and a description of each output file that can be created by PE Version 2.2.
