The EREPS models account for effects from optical interference, diffraction, tropospheric scatter, refraction, evaporation and surface-based ducting, and water-vapor absorption under horizontally homogeneous atmospheric conditions. EREPS revision 2.0 is an upgrade to revision 1.0 released in July 1988 (Hitney, 1988). There are two completely new programs in revision 2.0, COVER and PROPH, and a user-callable propagation-factor source code subroutine that may be helpful to anyone who wants to integrate the EREPS propagation model into their own applications program.
