Scientific paper

The D region collision frequency data of 19 rocket flights from Scandinavia are used to construct departures from the U.S. Air Force reference atmosphere. The model is a qualitative indication for either (a) a correction for the AFGL model at high latitudes in general, or (b) a transformation term for use in the European sector. The new temperatures fall within 10% percentiles previously reported, supporting hypothesis (a). Satellite-borne radiance measurements give a standing wave number 1 which, at 80 km has a maximum in winter at 220 W and a minimum at 40 W. The exact magnitude and altitude of this temperature wave, however, can not readily be retrieved from the radiance data. Nonetheless, these observations qualitatively support hypothesis (b). Also, such a longitudinal variation of up to 10 K is given in the AFGL model, for altitudes below 60 km.
