Abstract:

Oblique incidence ionospheric soundings originated at Puerto Rico have been recorded at Maynard, Mass. The course of the MOF is close to the F2JF predicted o-ray JF, especially in winter months. In summer months agreement is good if care is taken to segregate E sub s- and E-layer effects. Differential amplitude measurements made of F2 upper and lower rays near JF for selected days in a quiet month were compared with computed relative amplitudes in attempt to set limits on collisional absorption. Although assumed extrapolated mid-path profiles had many similarities, observed amplitudes do not generally follow predicted trend from models owing to incomplete description of the focusing, especially near JF. A crude upper limit on the peak F2 layer collisional frequency is 2000sec. Values much lower are plausible at any one time as reference to recent aeronomix electron temperature determinations suggests. Author
