Частотные характеристики вариаций параметров тропосферы и ионосферы в периоды прохождения солнечного терминатора

Abstract

T he paper presents an analysis of the spectra of atmosphere aerosol variations and variations Total Electron Content in the ionosphere (TEC). Monitoring of atmospheric aerosol performed with using of the two-wavelength (532, 1064 nm) atmospheric lidar (LSA-2S). Ionospheric TEC parameter determined from the observation of the navigation satellites signals GLONASS (Leica1200). The observations in the lower atmosphere and ionosphere were executed simultaneously in the period February — March 2012. Analysis of the observations showed that during the period of solar terminator passing in the lower and upper atmosphere, there are variations of parameters with periods close to the period Vaisala — Brunt in the lower atmosphere. It is assumed that such disturbances are excited in the lower atmosphere and propagate into the upper atmosphere. It is assumed that the disturbances with periods close to the period of the Vaisala — Brunt can take an important part in the implementation of dynamic relationships of lower and upper atmospheric layers.
