Our ray tracing programs are explained more fully in our ray tracing publications. Additional documentation is available at http://cires.colorado.edu/~mjones/raytracing/, which also gives updated versions of some of the subroutines.

Check the dates on the programs and subprograms on all web sites to see which versions are the latest.

Notice that computer program corrections indicated in errata have not been made to any of the ray tracing programs on the NOAA web site.
