✦ Synopsis

The nitric oxide densities obtained by the HALOE instrument aboard the UARS satellite present a unique set of measurements which can practically only be checked against the results of theoretical models or\ indirectly\ by comparison to ionospheric data[ Long!term averages of mesospheric nitric oxide "NO# data are contrasted to D!region electron densities from an empirical model which is based on a large number of appropriate in situ measurements[ Electron densities calculated with an ion!chemical model\ which uses HALOE ðNOŁ as an input\ tend to underestimate empirical electron densities below 79 km and overestimate it above 79 km[ The puzzling diurnal asymmetry of ðNOŁ may also be re~ected in the electron densities[ Þ 0887 Elsevier Science Ltd[ All rights reserved[
