Аннотация: Results of remote sensing of the Earth's upper atmosphere with the help of the astrophysical space station Astron, obtained using a tangent sensing arrangement and the ultraviolet wavelength region (273, 280 nm), are presented. Profiles of the aerosol scattering parameters at altitudes 50-100 km in the equatorial zone and at the miПоказать полностьюddle latitudes have been reconstructed. Vertical profiles of the ozone concentration at altitudes 55-65 km have been estimated as well. According to the data obtained, thick aerosol layers were observed between 65 and 100 km and near 50 km. It is established that after the spacecraft launch (Space Shuttle) a long-lived and extended anthropogenic aerosol layer is formed at altitudes about 100 km. No significant influence is found of the spacecraft launch on the aerosol scattering characteristics at altitudes from 50 lan and up to 85-90 km and on the ozone concentration between 55 and 65 km (the characteristic scale of horizontal averaging in tangent sensing is about 10(3) km).
