A theoretical model is used to examine the effect of quiet time electromagnetic drifts on O+/H+ behavior at L = 3.2. Starting with a depleted protonosphere, rapid changes occur in H+ tube content at L = 3.2 as the protonosphere is replenished, which causes tubes of plasma with different H+ contents to drift through this L value; the field-aligned proton flux is of the order of 10 to the 8th per sq cm per sec. As the drift lowers the altitude of the O+ layer during daytime, the values of NmF2 decrease due to the change in the linear loss coefficient. At night, cross-L gradients in NmF2 are significant for the conditions considered, and the outward drift increases NmF2 values at L = 3.2.
