Brief Description:
This program provides estimates of the effects of ionospheric scintillation
on the transionospheric radio channel for frequencies above 100 MHz. It is
based on a climatology of F-region electron-density irregularities that cause
scintillation (Secan et al. 1995, 1997) and a power-law, phase-screen
propagation model (Rino, 1979). The model is global, and includes variations
with solar cycle, season, geomagnetic disturbance levels, and local time.
