The critical frequency and electron density of the sporadic-E layer are estimated by calculating the minimum values to allow the reflection of the radio waves from the station requiring the highest critical frequency of the broadcast frequencies and distances observed. The following assumptions are used: (1) The height of the Es layer is 105 km, and (2) constant (no tilt), and that (3) the signal is affected only by the Es layer and not the temperature profile or weather in the elevations below the Es layer. Given otherwise similar parameters, the signal needing the highest critical frequency and electron density of the Es layer are those of shorter reflection distances or higher broadcast frequencies. The values listed were derived mathematically, but the 105 km height was used to compare values to the PROPLAB-PRO radio propagation computer program (which agreed reasonably well).
