Resumen:
Ionospheric long-term trend values can depend on several factors based on the estimation method. In the case of experimental data these factors can be filtering process, inappropriate selection of data, EUV proxy used, period analyzed, among many others. In the case of values obtained from modeling they can be quality of input parameters, models chosen for needed variables, and adequacy of model assumptions. A sensitivity analysis can give estimates of these factors effect since it is used to investigate how the variation in an ?output? can be attributed to variations in the ?input factors?. This work is a continuation of a previous work, where a sensitivity analysis of F2 layer trend values was partially made. We deepen this analysis and expand it to ionospheric conductivity and currents in an attempt to elucidate the joint roles of the anthropogenic effect and of the Earth´s magnetic field secular variation: their magnitudes, their ?competition?, and their possible interaction.
