We describe a FORTRAN computer program, CONPLT, that will generate plotting-command files for contour plots of the environmental models (e.g., sound speed, current or wind velocity, temperature) used with the acoustic ray tracing programs HARPO (underwater acoustics) and HARPA (atmospheric acoustics). Contours of environmental model parameters can be obtained in any vertical or horizontal slice through three-dimensional models. A companion report, PSGRAPH -- a Plotting Program for PC-HARPO, PROFILE, CONPLT and EIGEN, describes an associated computer program that produces PostScript files as well as screen graphics for PC-compatible computers. We include a floppy disk with computer programs and a sample case. Also included are instructions for obtaining the programs (with updates via Internet.
