Abstract A simple semi-empirical model to determine the maximum electron concentration in the ionosphere ( N m F 2 ) for South American locations is used to calculate N m F 2 for a northern hemisphere station in the same longitude sector. N m F 2 is determined as the sum of two terms, one related to photochemical and diffusive processes and the other one to transport mechanisms. The model gives diurnal variations of N m F 2 representative for winter, summer and equinox conditions, during intervals of high and low solar activity. Model N m F 2 results are compared with ionosonde observations made at Toluca-México (19.3°N; 260°E). Differences between model results and observations are similar to those corresponding to comparisons with South American observations. It seems that further improvement of the model could be made by refining the latitude dependencies of coefficients used for the transport term.
