Scientific paper
An analysis is made of Aureole 1 and 2 satellite data concerning latitude profiles of H(+) and He(+) ion density in the midlatitude and subauroral upper ionosphere. A description is given of measurements of subtroughs, i.e., sharp local decreases of H(+) ion density at midlatitude heights of 800-1500 km. Data on the location of the light-ion trough in the nighttime sector are compared with measurements of the main trough and the L-shell of its polar 'wall' in the lower F-region. L-shells of the plasmapause are shown to coincide with the diffuse-precipitation boundary during moderate disturbances. A scheme of ion convection and density at various heights in the nighttime subauroral F-region is proposed.
