This analysis shows that these ionospheric characteristics are poorly correlated. It is concluded that the daily values of the first characteristic cannot be estimated from the second by using a simple linear equation.202 157 - PublicationOpen AccessCorrelations in daily deviations from the median of f0F2, M(3000)F2 and VF(1994-05)

D.; Department of Electrical Engineering, University of Thessaloniki, Greece ;Zolesi, B.; Istituto Nazionale di Geofisica, Roma, Italy; ; ; The statistical analysis of the hourly daily deviations from the corresponding monthly-median values of the factor M(3000)F2 and of the critical frequency of the F2-layer, f0F2, reveals that the correlation between these parameters is poor. A similar analysis between the hourly daily deviations from the corresponding monthly-median of the height h’F and the f0F2 leads to similar results. These results indicate that the factor M(3000)F2, the height h’F and the critical frequency f0F2 may have a different daily variability.218 152
