The presented data, obtained with a retarding potential analyzer mounted on the AE-C satellite, show that the ion velocity distribution at high latitudes and below the F2 peak departs significantly from the Maxwellian configuration at ion temperatures greater than 1500 K. The current status of the theory of non-Maxwellian ion velocity distributions in the auroral ionosphere is reviewed, and the ways in which first-order theory can be used in the data analysis are discussed. The response of a retarding potential analyzer to the presence of a non-Maxwellian velocity distribution is examined, showing how the values of the various plasma parameters can be retrieved from the analyzer measurements for any shape of the ion velocity distribution. The shape of the one-dimensional ion velocity distributions in a plane perpendicular to the magnetic field is determined. The analysis indicates that at temperatures above 2000 K, interpretation of the retarding potential analyzer data can be seriously affected by the use of the normally assumed Maxwellian ion velocity distribution in the data inversion process.
