The GDM52 model can be used to predict dispersion at a
point or for a path. A FORTRAN program is provided to
calculate the dispersion for an arbitrary location or path.
Here are links to the required files:
A gzipped tar file,
GDM52_program.tar.gz, containing
all of the files mentioned below. When expanded, the tar
file will place files in a directory called ./GDM52_program
