The ITS-Jones-Haselgrove ray-tracing program is adapted to calculate acoustic-gravity ray paths in a compressible atmosphere with arbitrary three-dimensional wind and temperature variability and spherical earth. The program and its use are described, including deck listings and sample runs. Application to ocean acoustics should be possible with little modification.
