Abstract:

This report documents a high-frequency HF maximum usable frequency MUF model called MINIMUF-85. Developed at the Naval Ocean Systems Center, this semiempirical model permits simplified HF propagation MUF predictions to be performed in near-real-time. The model predicts the MUF for arbitrary input values of receivertransmitter position, date, time UT, and solar sunspot number. Several algorithms are contained in the model to describe the dependence of the MUF on solar activity, geomagnetic latitude, time of year, and time of day. An appendix contains the computer FORTRAN 77 code required to implement the fundamental features of this model. RRH
