Experimental electron densities for a mid‐latitude station and a simplified positive ion model consisting of O 2 + , NO + and their respective cluster ions are used in analyzing the normal day ion production and loss processes at 80 km for solar zenith angles 45° to 75°. Effective recombination coefficient and positive ion relative composition are calculated and compared with the experimental results. For a satisfactory agreement, the NO density is taken as 1.6 X 10 6 cm −3 , which is about an order of magnitude less than the generally accepted value from rocket studies. It is also shown here that q ∝ [ e ] is not valid at 80 km.
