Scientific paper

The results of the determination of electron density (N(sub e)) profiles at Volgograd, Heiss Island and Esrange ranges are discussed. Some of these profiles were obtained at solar zenith angles less than 90 deg, but at times near the sunset and others at night-time. The profiles obtained during the DYnamics Adapted Network for the Atmosphere (DYANA) campaign were compared with others in the past, with solar and geomagnetic indices as well as with the temperature and atmospheric ciruclation in the stratosphere and meosphere. The daytime electron densities below 85 km over Volgograd do not show any appreciable connection to the temperature. An anomalous period of low electron densities observed from February to the beginning of March rather seems to be connected with the meridional and vertical components of the atmospheric wind. We can speculate that the high night-time N(sub e) values at middle latitude may be considered as a manifestation of a post-storm effect. The relationship of the N(sub e) values at higher altitudes (greater than 80 km) and radio wave absorption seems to be connected with the atmospheric circulation and geomagnetic activity. The N(sub e) values in the polar cap region (Heiss Island) are below those at the same altitude in the auroral zone (Esrange), but higher than at middle latitudes (Volgograd). The N(sub e) values over Heiss Island seem to be connected with the geomagnetic activity and the meridional component of atmospheric circulation; the thermal control of the D-region cannot be excluded.
