- Abstract
- Applying the author's extrapolation procedure to a summer and a winter set of midlatitude nightime digital ionograms the uncertainty of the upper edge of the EF-valley is found to be up to 10 km but has no noticeable effect on the peak altitude determination. The retardation near fmin is 12 to 30 km.
