    Description: Profile calculations from ionograms using the Huang-Reinisch technique arrive at a set of boundary values and coefficients that describe the profile. From an ensemble of such sets an Average Representative Profile (ARP) is derived which is again expressed in terms of boundary values and coefficients.

    Description: Diurnal variations of the F1 region ionization at 170 km altitude and the slope ?170 = dN/dh at this height are analyzed for mid-latitude and equatorial stations: Millstone Hill, Ramey, Puerto Madryn and Jicamarca. Both the density N(t) and the slope ?(t)at 170 km show well defined diurnal variations with day-to-day variabilities of less than 10%. The heights of the F1 ledge, hmF1, are spread over ± 20 km and are therefore of limited value for modeling purposes.
