E.D. Tereshchenko, V.A. Turyansky, R.Yu. Yurik MODELING OF THE ALTITUDE-LATITUDINAL DISTRIBUTION VOLUME EMISSION RATE O(1D) BASED ON TOMOGRAPHIC RECONSTRUCTION OF ELECTRON DENSITY IN THE IONOSPHERE In February and March 2009, coordinated ground-based optical and tomographic observations were carried out by the Polar Geophysical Institute (PGI). The objective of this campaign was in studying properties of the red emission nightglow by using experimental data of the electron density images obtained by the satellite radio tomography. An optimized model of the volume emission rate for the atomic oxygen from the O(1D)-state is formulated and used in the data analysis. A comparison has been made between the observed line 630-nm intensity, tomographic electron density images and model distributions of the appropriate parameters by applying the NRLMSISE-00 and IRI-2007 models during quiet and slightly disturbed heliogeophysical conditions which reveals the dominant role of the ionospheric electron density in formatting the medium intensity red emission. The electron gas temperature distributions have been obtained in the region covered by the main ionospheric trough and the auroral latitudes. The electron temperature distribution values derived with using the images of the electron density and the volume emission rate as well as with the 630-nm emission intensities observed at one of the sites are found to be in a good agreement with the satellite ESRO-4 data obtained during similar heliogeophysical conditions. The results show that the total electron content data collected by the permanently operating satellite receivers in common with the developed modeling of the volume emission rates make it possible to study the red emission features in a wide area covered by the radio tomography chain taking advantage of electron density images.

Baddeley OBSERVATIONS OF THE STIMULATED ELECTROMAGNETIC EMISSION AT THE HIGH LATITUDES UNDER THE DIFFERENT MODES OF THE HEATING FACILITY The results of the HF interferometer measurements of the stimulated electromagnetic emission at high latitudes are presented. Stimulated electromagnetic emissions are observed during heating experiments at the SPEAR heating facility in 2010 and in 2011. The results show that under shot pulse durations there are specific components of the ponderomotive spectrum, which indicates the absence of thermal effects of the artificial modification of ionosphere. Once the duration of the heating facility radiation grows up to 50% of the duty cycle, the observed spectra are transformed into stationary thermal spectra, indicating that the structuring of ionospheric plasma and artificial ionospheric irregularities play an important role in the generation of the SEE spectral components. The thermal forms of the SEE could be generated by the low duty cycle mode of the HF heating under the preconditioning of the ionospheric plasma by natural processes of the high latitude ionosphere. The interferometric measurements of the signal arriving angles show that steady-state features of the SEE spectrum generated in the different regions with “fast” features. Excitation time differences of stimulated electromagnetic emission at high latitudes may be caused by a low power of the heating facility SPEAR, as well as possible drift of plasma in an electric field of high-latitude convection.
