Measurements of ionospheric parameters above Arecibo, Puerto Rico, have been compared with a computer simulation for a variety of conditions. Agreement was found between the measured and calculated electron concentration during geomagnetically quiet conditions. Comparisons for more active conditions indicate a significant upward flow of ionization during the mid-afternoon. Calculated electron temperatures were found to be consistently lower than measured temperatures during the daytime. Calculated values of NmF2 and h(max) agreed with measured results except during the post-midnight period. Calculated values of the ion flux indicate a 24-hour net flow of ionization from the northern to the Southern Hemisphere amounting to 12 percent and 6 percent of the equilibrium flux tube content above 1000 km for the winter solstice and equinox cases, respectively.
